This example is the first version of the simple mesh smoother. Here we will introduce \em iterators and \em circulators. These two concepts provide functionality to linearly enumerate e.g. all vertices of a mesh, and to circulate around a vertex, i.e. to enumerate all its one-ring neighbors. For a more detailed description, see \ref mesh_iterators. First we have to define the mesh type we want to use. This time we use a triangle mesh instead of a polygonal mesh: \dontinclude 02-iterators/smooth.cc \skipline TriMesh_ArrayKernel \skipline MyMesh
We read the mesh to be smoothed from a file: \skipline read_mesh
One smoothing iteration is done in two steps:
  1. For each vertex: calculate the barycenter of its one-ring neighbors.
  2. For each vertex: move the vertex to the computed barycenter.
This can easily be implemented using vertex iterators. The mesh provides begin and end iterators by vertices_begin() and vertices_end(). \skipline VertexIter \skipline v_it!=v_end
For calculating the barycenter, we have to iterate through the one-ring neighborhood of the current vertex. This functionality is provided by the VertexVertexIter: \dontinclude 02-iterators/smooth.cc \skipline VertexVertexIter \skipline vv_it=
Now we can calculate the barycenters for each vertex and store them in the array cogs: \dontinclude 02-iterators/smooth.cc \skipline std::vector \skipline v_it= \until cogs.push_back \until }
After we have calculated the barycenters all that is left to do is to move the vertices to the corresponding barycenters. The complete source code is listed below. \include 02-iterators/smooth.cc **/OpenMesh-11.0.0/Doc/images/0000770000174600017460000000000014556675336017420 5ustar gitlab-runnergitlab-runnerOpenMesh-11.0.0/Doc/images/class-hierarchy.png0000660000174600017460000014372314556675336023222 0ustar gitlab-runnergitlab-runnerPNG  IHDR?WsRGBbKGD pHYs[tIME 99r IDATxy$}'_Qy}v 0}J@ I܇ @kwkگwZ% !!X$@Bq3}UWuWבgdWQ]U]UqT z" tL#?3CU٧;O#f=cc|ËoBG9^NUueMs8N` ҭ)v rB+}VA8ӂj/NO$r(}1ͷ2_9ΊvSƫss?  5 &;_%"Rc/̋r>S_.k~6%>)EٴW8syG`]]6aDt _/'H!"X_DlxisnQ<~V=zcj`ݻG~GI?$@߲&4P׭Q,vFCT"ИgY.m)2"/b9om{Fq2bө%ڋ=K |ƣ1ߥZe5&N &xqR g͊bTQ(s2trި OڧV=_׭e2U*)׭1ABz킠V2˪m{q* KRZUxOL[WglODt:#ĶJ|-7Jsn"}D#$8vٓ^<;Ё"DbD];KW%k$K1"[+RÓzccC&avʷL3 O[tngfPhH"~em`@tٹўe4mm(}#=#X|7 6U*ψb}w&h6B繹x9H$>R(<8 k9ol~g^Uvw5AKv|\>;{LDI331ck_.%:XUQn >'=)YKuKӕ-.$;,@_-Ou/b7om4I"*o{ՔfK[~SE.)|<ŝ"?~=d./ܑ\ǩioi jad9^mۥhq ~P8U׵-k*{b,~4VNOZνsM$>Eraq]4' Aumccl]:}Q>',ov8N٫x "s;V{y8q8UݑdkĈ2袶<Ӷ ~$?c2"%I""zѦfB}AݤCg"X?7YޒgWjDDwU z!>zr,kO$rl/}e(x[u{XNhc#C ady/FZ]vohb&01!;qfz :wZMl =ŷL-?46E[+5/B'}7oH.O+}!ӔsOĿt8zgCWv!W*0U/b[6IBK,ڿj_:1߽?nKȶ熕+i=1'j/t٩ [nx ~$?k_>Qk'x^ rУfL̹]*=J?;{m{& i 3#>ӌ)XVNb7Z}4vY׭5G-,+_oH(U8hӋ6VݒBtDׅ?/*e_dƕ?|j@Y((M3~lj~;<ڦ;wW =E ѕa-]_5\n2xJ:u6,(WxS sA׍߬,Ar}t롞;VW77gKOD ݈1ym8u/F.Lr-nIRN ٿ'oN4B=cؤxoFkg&⸢dƷuYJi?LO-.Ogfa m]1ً\?f,'^jy]?%"w (\ w /X^[O W$9DwUwkCELNDbdƥ^^KtB')!Req&3Nl$ DDM>X[JO$}6.o;G >:t˹P^$rTDqqHer%gysӗJc|{%i1 uk1Ƙ( 5;MEz<̤)g1'rG/2(=g^TFhzr}?ۈqJ~﫦h|]/ B ȁX~7sh}T~.h{T$zm>^_2|_ׇ/A?zsn_d{/QV`_M_3=b`L\:qxxGq֧iR95Qsd`*)7t"ΝdCIff_z|%ev¾`W2צm ƕDnp"NY:6%^YS-dVfn؜ Ik]a{ lֱ>iMx͛ēgg['AO5pVrNALS,åt]Vs]C7W}oB[iI˹\~wwT~ my#9Ck${O?`r~a4wD_L3;̟`"ˈ$BgvI\uz7efjq/ї|=.+NOD33_'D,vj֖,k*0^Y5A1M;,1JdAsA?e(1ݍ1 t˭ƳُOۮ[&e9XHQ6{jOkod23躆 d9iGtz=pE@oU8q~h|f.\!QR$ӫ6}F_2h' .T(yy~m=UFǫA"]dQ"тK/;nwMDcD.эEZ=.+'a$A?A> v@k*x A?Z@7`@j9G\samX=$ZcVQ 6Q @>  3۞aBzGnl{1&90"OBck8 L*"FOZՔ@D~8Z j`Q6qT\~HښjY"-5 ֪M.曶W-Y1a0(Ah1aX7LXIE{kYsr2l쓴l!玦̘uCQ6JnmeL%q`msD415]GMps0Jg"V_@U]bA _!sD49y3 j`b\ҖqQڃ  ׭RAIdIJԅ[M\iD1˜(IH˚X$P*""|qBo|ؘΏs;HU;4ŶcB $I1]?3sߖKՐL~X^<~V#dl$X|w PhS(ڷxJ&ϝ?P5 /|N_\(<Iyd2Wwx1G_,gL { h_>;{|,I33wd$)ixG0yRg)C)u6&oBBe$J(18$:߲&2&x'k_j9SzlV r6 }Q7`XF (kx;psLmǙuZC^EQu]\X덄DQk^IX.Q׭9Nc%"I>d5[ɹR~`Sm&"׭,yEccOM}$)kYMs׻^6"sXworM$JjY{4TW~䗼A2 }^oSko:Ni gSw?q,uhyׁ/t,gi8 Ӏ/VjconEQt)Rtj/U;GD-mɆٽki,NHRl{Z}0#9>{ oy7pyp̓c$o֛A_R1wh]֫hQccիb5~3JΦif ={>KK;\u=ݲs'Pˇ(~jťzTzw/RQ}䉦=޸G9.ROklJʦ£DĘ>(5=d3D$IɛR5o Ʊ~}H*uq=G NqtDf~ rnd۳^WfVlrGvj;aI$Jj%)!9۞p\Z׭[^Ӷ9-q@]?\ir\p]cl:U"X*x*IYg̩\nV8w,k"=T)1 JR:885m{:}9wlJ]ix#s㠖ޖBP5o "EGD5ik]ܱ= 3D$|A(icG4z[ڋȻ+l\ͩдm[#pPhJ623Z IDATq&sE،x MME9UNV*=^=5#5tpxZ mt 5M]?0lrʳoKEu]fks~DpTcdi:}ip76d27B^$.6](py̓8OOZnc$rzJ_6?Z362;C[UV<2eo-,3C?sׁ-m|-3b9pW.ƘV7Lٹ#ݺJDs~FV{9Rd, mL$>lD1 ꫩԅfBD$SMswR˜}XӜFO H]QL$>dYaHw[L<~f(Yt/xL˚mF]?s_y̓~Y$A#AU͉9f{d+٫5HQ3&2&JRB׏_Xx9kLO0vNjb ([V/t~DM̌l*|\Q}Q7Opu.s[ =7!~H.AA 3>}03$).I0[ف~Xӿ6gL u'Vz7ha]MQf~ϟN_*Ų9H5 0R4PHށ߃zd{P 0tA?a`[U0`oa 1cX1"XuwPpaL? `0A?A? `0A?NA? `0vA?~A? `0jA?>o9G- nV@A?  ~@19j`o^C%*qP{]Q jwޏJX0A? @0e'>aD?,Yssd\m|x i3qbDur gMAr ׭ Ԝp 6]2u:BHZ%Zt|לO+Ӻ q]jccsra=q]ò_jQ[C2X{gs†uB+}VA8 oJ]LDo]R-R~sk-p(" kŅ6E2Z28{"\-7J8Y/$73%2"~@'G ktE1ߵe e/V,v$źߴ>rVG{Kk3:AXwYY K(]g:>ľ` bwiGqn]e975H"l* 6dsl-I$ tLDw8DDD:]WjH}5IoT[@]MO*P. zۨ X ?.m_!XYB}QSv*ʁVd,䷊[>+P.bstx`%BD*)NUfaxCZ ~E":>&VR-SB*l~\$K1"[+R'$ȨY_jjN{,v$H<_Yt[BN\L׏wqV40z(hӱiAPA\AQdWYdYNG"^׭$g+FQTAd8|ܲśPQ6,gB T$.x7I쇾NKegW\xRT I $$%tTB׭@sœG+s;HU{v!8SQ6ʘ lJ$δB)x#y,AŰnM/pD>Rƈar\zFDĈW.'D8E^'ܚd7'ؙ*D 1 t|]ݝx@fHLHD ^#:(KlD*#(++?d~eC$)'ҹ*ݝbfC OPwfǖ˿n_9;Tz,ӶH.,3T<#]77|3:?oktHy`'HcF|uI mq8|x薜t켱kv/ByUjyTAO/9 ,{4JٖT&~<Ņ~of&?{nJYA<3l'YE$"Qg8Fff94ɍ':}8%wz}9c&'(;@$"zȠ{|զѽUӹ^ܗk8#lKMICgiDDOt;h=pƥ(0+i ٕ:.̈]X|(9THŝcߞ~RmWM+''o^v;};<855 px"2]1] @UjoF6{ Tz$4PEٿZ}qk[T,\n/8]?BQ|9jyIǥD^į(.5Ms2@T׭LO66esj8|Q8Ls,٫m˹-j2ye\׶W4{}>7CIJg;8\n$ehcF/;%OBXi(+5ҡgwk<7.eΥ_ ^T]ENDtB':&)S'#Чbvt,AeNYwksԾ 7h%5}i`J+'C5>Tu ,gav^"t͂0&B~z[~Ry\lfLb,45trKQ6U*ϩ6AP%);7h^\28 KNzkXIwd(?,˹d2Wzu57e} zP!;SbV{mjj(F/۞- "ƤjHR1QߩV_ V{yj˂29ZeZ]ˠqF/xoVxˍ7!U ͶwKy1RW+4F_1,.NUtD_^dB_||o~D R[>-w_VNQ8|45ﲭiۓ\P<0ړݸ7>ܬK'o ߞXCgfUQymzd5NlKReM{t腮Iic}ۤӗyzѓC[B#s;ob%:Nf8.5ݨYYDwU[_%w0i%h7O(=s.,DD*7G=YLãe-wC7ȻARYx뿧+*-)`ѯ~HgC p~$M;un+]v =UyEq;qyyâ!")

As we already have seen, we can bind additional data to the mesh entities by means of properties. %OpenMesh provides a set of so-called standard properties. Unlike the custom properties these have some special features and a different interface, which are the matter in this tutorial. The following table lists all available standard properties and the suitable entity for which it can be used.
  Vertex Face Edge Halfedge
Color X X X  
Normal X X   X
Position (*) X      
Status X X X X
TexCoord X     X
To add a standard property to an entity simply use the appropriate request method, e.g. \c request_face_normals(). The only exception is the position (*). It cannot be added because it is permanently available, hence it cannot be removed as well. In this example we -# add vertex normals to a mesh object -# load a file -# check if the file provides vertex normals and calculate them if not -# move every vertex one unit length along its normal direction -# print the resulting positions to std::cout Let's start with adding vertex normals to the mesh: \dontinclude 05-std_properties/properties.cc \skipline request_vertex_normals In a similar manner we can request the other standard properties. For example the face normals: \skipline request_face_normals We need them to calculate the vertex normals with \c update_normals(), if the file didn't provide any. But we can do more with standard properties. We can verify if the mesh has already the property vertex normals \dontinclude 05-std_properties/properties.cc \skipline has_vertex_normals \until } And after usage we remove them again \skipline release_vertex_normals But, what happens if for example the vertex status property has been requested twice? Then the first release does nothing, but the second one will remove it. The standard properties have a reference counter, which is incremented by one for each request and decremented by one for each release. If the counter reaches 0 the property will be removed from memory. As we have seen in the table above, we have 9 dynamically requestable properties. The request functions as defined in OpenMesh::Concepts::KernelT are:
  • request_edge_status()
  • request_edge_colors()
  • request_face_colors()
  • request_face_normals()
  • request_face_status()
  • request_face_texture_index()
  • request_halfedge_status()
  • request_halfedge_normals()
  • request_halfedge_texcoords1D()
  • request_halfedge_texcoords2D()
  • request_halfedge_texcoords3D()
  • request_vertex_colors()
  • request_vertex_normals()
  • request_vertex_status()
  • request_vertex_texcoords1D()
  • request_vertex_texcoords2D()
  • request_vertex_texcoords3D()
Added properties can be released by the following functions:
  • release_edge_status()
  • release_edge_colors()
  • release_face_colors()
  • release_face_normals()
  • release_face_status()
  • release_face_texture_index()
  • release_halfedge_status()
  • release_halfedge_normals()
  • release_halfedge_texcoords1D()
  • release_halfedge_texcoords2D()
  • release_halfedge_texcoords3D()
  • release_vertex_colors()
  • release_vertex_normals()
  • release_vertex_status()
  • release_vertex_texcoords1D()
  • release_vertex_texcoords2D()
  • release_vertex_texcoords3D()
A property's existance can be tested with
  • has_edge_status()
  • has_edge_colors()
  • has_face_colors()
  • has_face_normals()
  • has_face_status()
  • has_face_texture_index()
  • has_halfedge_status()
  • has_halfedge_normals()
  • has_halfedge_texcoords1D()
  • has_halfedge_texcoords2D()
  • has_halfedge_texcoords3D()
  • has_vertex_colors()
  • has_vertex_normals()
  • has_vertex_status()
  • has_vertex_texcoords1D()

which return true if a property has been requested before and is available. The status property is used for marking geometry elements i.e. as selected or deleted. See \ref tutorial_07b for further information. Now we know how to add and remove standard properties, but how do we access them? Again we need the mesh object. Unlike the custom properties, where we accessed one with the mesh member function \c property(), for each standard property the mesh provides a get and a set method. We have used one pair of get/set methods already in the previous three tutorials, where we computed a new location for the vertex position. Here we move all vertices a unit length along their normal direction: \dontinclude 05-std_properties/properties.cc \skipline MyMesh::VertexIter \until { \skipline mesh.set_point \skipline } The get-methods take an entity handle and return the value of the desired property, and the set-methods require an additional parameter to pass the new value to the property. According to the table not every pair of get/set-methods apply to every entity. For example a face has normally no texture coordinates, hence a call to \c mesh.texcoord2D( _face_handle ) will result in an error when compiling the code. Since we know how to add/remove/access standard properties, one further question remains. What data types do they have? And are there more hidden secrets? The next tutorial (\ref tutorial_06) will give the answer. The complete source looks like this: \include 05-std_properties/properties.cc */ OpenMesh-11.0.0/Doc/operations.docu0000660000174600017460000001054114556675336021214 0ustar gitlab-runnergitlab-runner/** \page mesh_operations Some basic operations: Flipping and collapsing edges In this section you will learn about some basic operations on a mesh that %OpenMesh already provides. Comprising the flipping of edges in a triangle mesh as well as collapsing edges by joining the two adjacent vertices. \li \ref op_flip \li \ref op_collapse \section op_flip Flipping edges in triangle meshes Considering two adjacent faces of a triangle mesh, there exist exactly two different configurations of the inner edge. Calling the function OpenMesh::TriConnectivity::flip(EdgeHandle _eh) will flip the specified edge to its opposite orientation as shown in the illustration below. \image html mesh.flip.png "Flipping edges in a triangle mesh" So, the following snippet of code shows how to use this in your applications: \code TriMesh mesh; // Add some vertices TriMesh::VertexHandle vhandle[4]; vhandle[0] = mesh.add_vertex(MyMesh::Point(0, 0, 0)); vhandle[1] = mesh.add_vertex(MyMesh::Point(0, 1, 0)); vhandle[2] = mesh.add_vertex(MyMesh::Point(1, 1, 0)); vhandle[3] = mesh.add_vertex(MyMesh::Point(1, 0, 0)); // Add two faces std::vector face_vhandles; face_vhandles.push_back(vhandle[2]); face_vhandles.push_back(vhandle[1]); face_vhandles.push_back(vhandle[0]); mesh.add_face(face_vhandles); face_vhandles.clear(); face_vhandles.push_back(vhandle[2]); face_vhandles.push_back(vhandle[0]); face_vhandles.push_back(vhandle[3]); mesh.add_face(face_vhandles); // Now the edge adjacent to the two faces connects // vertex vhandle[0] and vhandle[2]. // Find this edge and then flip it for(TriMesh::EdgeIter it = mesh.edges_begin(); it != mesh.edges_end(); ++it) { if(!mesh.is_boundary(*it)) { // Flip edge mesh.flip(*it); } } // The edge now connects vertex vhandle[1] and vhandle[3]. \endcode \section op_collapse Collapsing edges In this section you will learn how to collapse edges such that the two adjacent vertices join. %OpenMesh provides the function OpenMesh::PolyConnectivity::collapse(HalfedgeHandle _heh) to perform this operation. This will collapse the from-vertex (remeber that halfedges are directed) to the to-vertex of the halfedge as illustrated below. Note that collapsing edges might cause topological inconsistencies to your mesh. You should verify consistency after collapsing edges by calling OpenMesh::PolyConnectivity::is_collapse_ok(). \note You have to request status attributes in order to use the collapse and delete functions! \image html mesh.collapse.png "Collapsing will always be performed in the direction the halfedge points to." A simple code example related to the illustration might look like this: \code PolyMesh mesh; // Request required status flags mesh.request_vertex_status(); mesh.request_edge_status(); mesh.request_face_status(); // Add some vertices as in the illustration above PolyMesh::VertexHandle vhandle[7]; vhandle[0] = mesh.add_vertex(MyMesh::Point(-1, 1, 0)); vhandle[1] = mesh.add_vertex(MyMesh::Point(-1, 3, 0)); vhandle[2] = mesh.add_vertex(MyMesh::Point(0, 0, 0)); vhandle[3] = mesh.add_vertex(MyMesh::Point(0, 2, 0)); vhandle[4] = mesh.add_vertex(MyMesh::Point(0, 4, 0)); vhandle[5] = mesh.add_vertex(MyMesh::Point(1, 1, 0)); vhandle[6] = mesh.add_vertex(MyMesh::Point(1, 3, 0)); // Add three quad faces std::vector face_vhandles; face_vhandles.push_back(vhandle[1]); face_vhandles.push_back(vhandle[0]); face_vhandles.push_back(vhandle[2]); face_vhandles.push_back(vhandle[3]); mesh.add_face(face_vhandles); face_vhandles.clear(); face_vhandles.push_back(vhandle[1]); face_vhandles.push_back(vhandle[3]); face_vhandles.push_back(vhandle[5]); face_vhandles.push_back(vhandle[4]); mesh.add_face(face_vhandles); face_vhandles.clear(); face_vhandles.push_back(vhandle[3]); face_vhandles.push_back(vhandle[2]); face_vhandles.push_back(vhandle[6]); face_vhandles.push_back(vhandle[5]); mesh.add_face(face_vhandles); // Now find the edge between vertex vhandle[2] // and vhandle[3] for(PolyMesh::HalfedgeIter it = mesh.halfedges_begin(); it != mesh.halfedges_end(); ++it) { if( mesh.to_vertex_handle(*it) == vhandle[3] && mesh.from_vertex_handle(*it) == vhandle[2]) { // Collapse edge mesh.collapse(*it); break; } } // Our mesh now looks like in the illustration above after the collapsing. \endcode */ OpenMesh-11.0.0/Doc/CMakeLists.txt0000660000174600017460000000053414556675336020716 0ustar gitlab-runnergitlab-runnerinclude (VCIDoxygen) IF (DOXYGEN_FOUND) # Add a documentation install target vci_create_doc_target(doc-install) if (TARGET doc-install) vci_copy_after_build (doc-install "${CMAKE_BINARY_DIR}/Build/${VCI_PROJECT_DATADIR}/Doc/html" "${CMAKE_INSTALL_PREFIX}/${VCI_PROJECT_DATADIR}/doc/html") endif() ENDIF(DOXYGEN_FOUND) OpenMesh-11.0.0/Doc/Tutorial/0000770000174600017460000000000014556675336017756 5ustar gitlab-runnergitlab-runnerOpenMesh-11.0.0/Doc/Tutorial/05-std_properties/0000770000174600017460000000000014556675336023246 5ustar gitlab-runnergitlab-runnerOpenMesh-11.0.0/Doc/Tutorial/05-std_properties/properties.cc0000660000174600017460000000347014556675336025756 0ustar gitlab-runnergitlab-runner#include // -------------------- #include #include typedef OpenMesh::TriMesh_ArrayKernelT<> MyMesh; int main(int argc, char **argv) { MyMesh mesh; if (argc!=2) { std::cerr << "Usage: " << argv[0] << " \n"; return 1; } // request vertex normals, so the mesh reader can use normal information // if available mesh.request_vertex_normals(); // assure we have vertex normals if (!mesh.has_vertex_normals()) { std::cerr << "ERROR: Standard vertex property 'Normals' not available!\n"; return 1; } OpenMesh::IO::Options opt; if ( !

The modules compute a priority value due to some error metric, which is used by the decimater to feed a priority queue. The lower the error value, the more a potential collapse moves to the front of the queue. The one with the lowest error will always be the candidate for the next collapse. This implementation does a halfedge collapse, hence simply collapsing one vertex into another connected by a halfedge. \note The decimater ignores all 'locked' and 'deleted' vertices (see OpenMesh::Attributes::StatusBits) \attention The decimater sets temporarily the status bit 'tagged' and clears it after usage regardless of a previous state. \section DecimaterLock Block vertices from beeing touched by the Decimater You could mark vertices as locked, which should not be modified by the decimater. \code // That might be already requested mesh_->request_vertex_status(); // Get an iterator over all halfedges Mesh::HalfedgeIter he_it, he_end=mesh_->halfedges_end(); // If halfedge is boundary, lock the corresponding vertices for (he_it = mesh_->halfedges_begin(); he_it != he_end ; ++he_it) if (mesh_->is_boundary(*he_it)) { mesh_->status(_mesh->to_vertex_handle(*he_it)).set_locked(true); mesh_->status(_mesh->from_vertex_handle(*he_it)).set_locked(true); } \endcode \section DecimaterMod Decimating Modules The vertex to be removed is determined by a decimation module, which has to be derived from OpenMesh::Decimater::ModBaseT. The framework supplies already a few decimation modules. But it's very easy to build your own (\ref OpenMesh::Decimater::ModBaseT). The most important function of a decimation module is OpenMesh::Decimater::ModBaseT::collapse_priority(). It takes an OpenMesh::Decimater::CollapseInfoT describing a potential halfedge collapse, and returns a value due to some error metric. The error value is used by the decimater to feed a priority queue. Collapses with low error will be executed first, and those with large error later. Of course a module computing the error quadric is provided (OpenMesh::Decimater::ModQuadricT). This framework allows to use more than one decimation module with some restrictions. Since the error value is always normalized and sometimes very difficult to compare to other metrics, the framework allows only one non-binary module, i.e. a module computing a float value. Every further module must be a binary module, i.e. collapse_prioerity() returns OpenMesh::Decimater::ModBaseT::LEGAL_COLLAPSE or OpenMesh::Decimater::ModBaseT::ILLEGAL_COLLAPSE. In the algorithm the binary modules are evaluated first. If the evaluated collapse passes the test, then the non-binary module contributes to the decision step. In some cases the module does not contribute anything to the decision engine of the decimater, but instead, e.g. simply collects information, while the decimater does it's work. For instance the module OpenMesh::Decimater::ModProgMeshT collects information from all collapses that have been done. This information can be used to generate progressive meshes as described in "Progressive meshes", Hoppe, 1996. Provided decimation modules(Binary: B, Continuous: C, Special: X): - OpenMesh::Decimater::ModAspectRatioT (B,C) - OpenMesh::Decimater::ModEdgeLengthT (B,C) - OpenMesh::Decimater::ModHausdorffT (B) - OpenMesh::Decimater::ModIndependentSetsT (B) - OpenMesh::Decimater::ModNormalDeviationT (B,C) - OpenMesh::Decimater::ModNormalFlippingT (B) - OpenMesh::Decimater::ModProgMeshT (X) - OpenMesh::Decimater::ModQuadricT (B,C) - OpenMesh::Decimater::ModRoundnessT (B,C) \section DecimaterHnd Module Handles Similar to properties the modules are represented outside the decimater by module handles. Before using the decimater a non-binary module must be registrated with the decimater. See \ref DecimaterExa. \section DecimaterExa Basic Setup The following small example show the basic steps to setup up a decimater: \include decimater.cc */ OpenMesh-11.0.0/Doc/tutorial_12.docu0000660000174600017460000000347614556675336021207 0ustar gitlab-runnergitlab-runner/** \page tutorial_12 Filtering ranges with predicates This examples shows: - How to use predicates to filter which elements of a mesh you want iterate over In the previous tutorial we discussed already that the ranges returned by functions like all_vertices(), voh_range() or outgoing_halfedges() provide a few helpful methods such as avg() or to_vector(). Another interesting method is filtered() which requires as argument something that can be called for an element of the range and returns a bool. The resulting range will then only iterate over elements for which the filter returs true. The filter can be a lambda, a function pointer, a property manager holding a bool property, or a functor object such as the predicates defined in . The predefined predicates can check the status of a mesh element and test if they are boundary. With their help you can for example count all boundary vertices: \dontinclude 12-predicates/predicates.cc \skipline Count boundary vertices \until boundary vertices Predicates can be composed using the operators ||, &&, and !. This enables you to specify precisely which elements you want process in your loop, e.g. inner vertices that are selected: \skipline Selected inner vertices \until std::cout << std::endl As mentioned above, the filter argument can be anything returning a bool for a given input, e.g. a function pointer: \skipline Faces whose id is divisible by 3 \until faces whose id is divisible by 3 However, function pointers, lambdas etc are not composable. Fortunately, you can use make_predicate to turn them into composable predicates: \skipline Faces which are tagged or whose id is not divisible by 3 \until faces which are tagged or whose id is not divisible by 3 Below is the complete source code: \include 12-predicates/predicates.cc --- */ OpenMesh-11.0.0/Doc/tutorial_build.docu0000660000174600017460000000472614556675336022063 0ustar gitlab-runnergitlab-runner/** \page tutorial_build_internal_apps How to create your own project inside OpenMesh In this tutorial we will explain, how to create a new app inside the source code of %OpenMesh and compile it with the CMake build system.

\section build_systems Chosing build system %OpenMesh can be built using the cmake build system.

\section sec_compiling_unix Unix \subsection linux_using_cmake Compiling OpenMesh using CMake In order to compile %OpenMesh, create a directory named e.g. "build" in OpenMesh's root directory. Change to the newly created directory and type

cmake ..            ## Generates the appropriate Makefiles
make                ## Builds the project

\warning If your compiler does not support c++11 natively, you might have to enable it by changing the cmake call to:
cmake .. -DCMAKE_CXX_FLAGS=-std=c++98 You can choose the build type by using cmake with the flag
-DCMAKE_BUILD_TYPE=(Debug|Release) The default is: Release
Other flags are:
-DBUILD_APPS=OFF to disable build of applications and
-DCMAKE_INSTALL_PREFIX=<path> to specify the install path.
When calling make install cmake will install %OpenMesh into this directory using the subdirectories lib/include/bin. CMake builds both shared and static under Linux. Everything will then be build in the Build subdirectory containing the libraries in lib and the binaries in bin. There are some additional targets:
doc: Builds the Documentation
doc-install: Builds the Documentation and installs it

\note When you link against the static libraries of OpenMesh and get the error "can not be used when making a shared object; recompile with -fPIC" you need to add "-fPIC" to the CMAKE_CXX_FLAGS. (This is usually added automatically) \section sec_compiling_windows Windows \subsection windows_using_cmake Compiling OpenMesh using CMake Building OpenMesh on Windows requires cmake to generate the project files for Visual Studio.
  • Get Visual Studio ( 2015-2017 )
  • Extract %OpenMesh source code.
  • Get all required libraries and install them ( including headers! ).
  • Download and install cmake: www.cmake.org.
  • Start the cmake gui and open the %OpenMesh toplevel directory as source directory
  • Choose a build directory (e.g. create a directory called "build" in OpenMesh's root folder)
  • Click on configure .... If any libraries are left unconfigured, you can adjust the path manually. Rerun configure until everything is configured correctly.
    Attention: Some build variables are only visible in advanced view mode. Select Visual Studio 9 (2008), Visual Studio 10(2010), Visual Studio 11 (2012), Visual Studio 12 (2013) (Depending on your version) as generator.
  • Click generate to create the visual studio project files
  • You can now find a Visual Studio solution file (OpenMesh.sln) in the build directory you chose in cmake
  • Now you can build %OpenMesh from within Visual Studio using the newly created project file.


\section sec_compiling_macosx MacOS X To compile OpenMesh, you need cmake on your system which is the minimal requirement to build OpenMesh. We recommend using homebrew (https://brew.sh/index_de) for installing additional packages required for compiling OpenMesh or other projects. After installing homebrew, you can use the following command to install cmake:
brew install cmake            ## cmake generates the makefiles

Optional libraries which can be used to build OpenMesh:
brew install googletest            # Required to compile the included tests
brew install qt            # Required to compile the included UI example apps

Download and install required libraries as stated above. You can download %OpenMesh's sources from www.openmesh.org or check out the latest repository via GIT (Recommended to get the latest version of OpenMesh):
https://gitlab.vci.rwth-aachen.de:9000/OpenMesh/OpenMesh.

\subsection mac_using_cmake Compiling OpenMesh using CMake We recommend you to use CMake >= 3.7 as build system. This can also easily be installed via Homebrew as well as the Qt >= 6.2 library which is used for some example applications in %OpenMesh.
Once installed, change to %OpenMesh's root directory and create a directory named e.g. "buildDebug" (assuming you want to build with debug symbols).
Then type in the following command to initially set up the build environment:

cmake ..            ## Generates the appropriate Makefiles
Note: If the build directory is not a subdirectory of %OpenMesh's root folder, replace ".." with %OpenMesh's absolute (or relative) path. In order to manually set specific build variables, just type:

ccmake .            ## Configure build environment
This opens the CMake configure tool. Change the CMAKE_BUILD_TYPE variable to "Release" in order to prepare build for release configuration. Now, when everything is set up, just type:

make                ## Build %OpenMesh
And optionally:

make doc            ## Build %OpenMesh's documentation
The mac application bundle will be found under "Build" in the recently created build folder. It automatically contains all needed shared objects (libs, fonts, textures, etc.). CMake builds both shared and static under MacOS X. **/ /** \page compiling_tests Compiling OpenMesh unit tests %OpenMesh comes with a set of unittests for all platforms. In order to run these tests, you need to enable the cmake flag OPENMESH_BUILD_UNIT_TESTS. You also need GoogleTest on your machine. Configure the cmake variables in OpenMesh to point to your GTest include dirs and libraries (check the Advanced button in cmake, if you don't see these options). Than run cmake and build OpenMesh. Afterwards you should have a Unittests subdirectory in your binary build folder. This directory includes the unittest executables and several test files for input and output checks. You can run the executables directly, but make sure, that the working directory is the directory where the executables are. **/ //----------------------------------------------------------------------------- OpenMesh-11.0.0/Doc/mesh.docu0000660000174600017460000011510414556675336017766 0ustar gitlab-runnergitlab-runner//----------------------------------------------------------------------------- /** \page mesh_first_to_read Notes on template programming Please note, that %OpenMesh makes heavily use of C++ templates, generic programming and all that stuff (see \ref mesh_cpp). Therefore read this section carefully (else you get lost in the reference manual):

There is no such thing like the %OpenMesh class

The library provides a set of classes ( 99% templates ;-) ), where the inheritance relationship is given by template parameterization. You might ask: "What the heck is that?" It means, a parent class is passed as a template argument to another class: \code class P1 { } class P2 { } template class B : public Parent {} typedef B fooB1; typedef B fooB2; \endcode Voila, we have created two different types of B. Depending on the interface, the public member elements, provided by \c P1 or \c P2, \c fooB1 and \c fooB2 might have different behaviours or even different interfaces! But if \c P1 and \c P2 have the some interface or at least a common interface, then from programming point of view there is no difference using \c fooB1 or \c fooB2. And this is all about. %OpenMesh defines an interface concept for the kernel which is documented in \ref OpenMesh::Concepts::KernelT. As long as the kernel provides this the class handling polygonal meshes \c OpenMesh::PolyMeshT can use any kernel.

Therefore documentation resides in two spaces

-# Associated with the class/struct (as usual) -# In a concept class in cases like the example code above. Hence, if you want to know what a mesh type has to offer refer to OpenMesh::Concepts::KernelT, OpenMesh::PolyMeshT, OpenMesh::TriMeshT. */ //----------------------------------------------------------------------------- /** \page mesh_features Features and Goals of OpenMesh The main features of the underlying data structure are: \li No restriction to triangles meshes, handle general polygonal meshes. \li Explicit representation of vertices, halfedges, edges, and faces. \li Efficient access to the one-ring neighborhood of a vertex. \li Ability to handle non-manifold vertices (like two faces meeting in only one vertex). The goals/features of the C++ implementation are:
  • Flexibility:
    • Choose suitable types for scalars and coordinates (e.g. float, double, exact arithmetic and two-, three-, or n-dimensional points).
    • Enhance each item type by your own attributes/properties, like e.g. adding a normal vector or a \c FaceHandle to class \c Vertex.
  • Efficiency:
    • Avoid the overhead of virtual inheritance and virtual function calls.
    • Resolve as many type/attribute dependencies as possible at compile-time instead of testing for attributes at run-time (e.g. normal vectors for faces).
  • Type-safety for handles, no type-casting (*): Vertices, (Half-)Edges, Faces know each other and their corresponding handles. (*) Since version 0.10.0 the Microsoft VisualC++ compiler is supported. Due to the compilers inaptitude to process forwards on template functions correctly, the type-safety had to be given up to some extend. Though under the hood void pointers are used, the casting is done within the mesh, and the user transparently uses his handles as before.
    As soon as the compiler adheres to the C++ standard the type-safe version will be restored.
*/ //----------------------------------------------------------------------------- /** \page mesh_cpp Some words on the C++ implementation If one takes a look at the goals and features section it soon becomes obvious that these goals cannot be achieved using trivial C++ features only. We make heavy use of templates, (partial) template specialization, generative and generic programming, and the STL. This may be a challenge for you as well as for your compiler, as these are quite late features of the C++ language. While knowledge of generative programming is only necessary if you want to create your own mesh kernels or extend iterators or similar types, you will \b NOT need it for simply using these things. Nevertheless working knowledge of C++ and basic knowlege of templates is required. To get into this stuff we recommend the following books: \li Bjarne Stroustrup, The C++ Programming Language , \li Matthew H. Austern, Generic Programming and the STL: Using and Extending the C++ Standard Template Library , \li Andrei Alexandrescu, Modern C++ Design: Generic Programming and Design Patterns Applied , \li Krzysztof Czarnecki, Ulrich Eisenecker, Generative Programming: Methods, Tools, and Applications . */ //----------------------------------------------------------------------------- /** \page mesh_hds The Halfedge Data Structure This section describes the underlying data structure that is used to store the mesh entities (items) vertices, edges, faces, and their connectivity information. There are many popular data structures used to represent polygonal meshes. For a detailed comparison of them refer to the papers at the end of this section. The data structure used in this project is the so called halfedge data structure . While face-based structures store their connectivity in faces referencing their vertices and neighbors, edge-based structures put the connectivity information into the edges. Each edge references its two vertices, the faces it belongs to and the two next edges in these faces. If one now splits the edges (i.e. an edge connecting vertex \c A and vertex \c B becomes two directed halfeges from \c A to \c B and vice versa) one gets a halfedge-based data structure. The following figure illustrates the way connectivity is stored in this structure:
\image html halfedge_structure3.png
  • Each \b vertex references one outgoing halfedge, i.e. a halfedge that starts at this vertex (1).
  • Each \b face references one of the halfedges bounding it (2).
  • Each \b halfedge provides a handle to
    • the vertex it points to (3),
    • the face it belongs to (4)
    • the next halfedge inside the face (ordered counter-clockwise) (5),
    • the opposite halfedge (6),
    • (optionally: the previous halfedge in the face (7)).
Having these links between the items, it is now possible to circulate around a face in order to enumerate all its vertices, halgedges, or neighboring faces. When starting at a vertex' halfedge and iterating to the opposite of its previous one, one can easily circulate around this vertex and get all its one-ring neighbors, the incoming/outgoing halfedges, or the adjacent faces. All this functionality is encapsulated into the so-called circulators , described in \ref mesh_iterators. \attention In order to efficiently classify a boundary vertex, the outgoing halfedge of these vertices must be a boundary halfedge (see OpenMesh::PolyMeshT::is_boundary()). \attention Whenever you modify the topology using low-level topology changing functions, be sure to guarantee this behaviour (see OpenMesh::PolyMeshT::adjust_outgoing_halfedge()) While one does not need to store the previous halfedge (7) explicitly, because it can be derived from the links to the next halfedges, one may do so for the sake of performance. In fact, the previous halfedge is stored by default (OpenMesh::DefaultTraits). Using traits and attributes the previous halfedge can removed, to gain memory. This kind of mesh customization is explained in \ref mesh_type. While the halfedge-based structures usually consume more memory than their face-based counter-parts they have the following important advantages: \li It is easy to mix faces of arbitrary vertex count in one mesh. \li We now have an explicit representation of vertices, faces, \em and edges/halfedges. This becomes extremely useful if one has to store data per edge/halfedge since this can easily be modelled by member variables of these types (see \ref mesh_type). \li Circulating around a vertex in order to get its one-ring neighbors is an important operation for many kinds of algorithms on polygonal meshes. For face-based structures this leads to many if-then branchings, the halfedge structure provides this funcionality without conditional branching in constant time. References S. Campagna, L.

Please note! Most of the inheritence relationships are realized by template parameterization! Therefore some of the inheritance links are not documented in a inheritance graph in the reference. This picture shows the overall concept. \image html class-hierarchy2.png \section ch_kernel Building the kernel -# The BaseKernel defines the basic operations on properties like add/remove/access. -# Next the AttribKernelT adds the standard properties all associated methods. -# Finally the ArrayKernelT provides the methods to add/remove/access the mesh items vertices, (half-)edges, and faces.

Looks simple, but it isn't - it's a bit more complicated: \include build-trimesh.cc To generate the actual mesh type the helper template class \c TriMesh_ArrayKernel_GeneratorT is used. It takes the traits in a template argument and passes it to \c FinalMeshItemsT to get the final type of the mesh items (MeshItems). The \c MeshItems defines the types for Point, Normal, Color, TexCoord, Vertex, and for all mesh items. With the help of \c MeshItems create the type of the \c AttribKernel, which defines the apropriate standard properties for the items. Finally use \c AttribKernel and \c MeshItems to create the mesh kernel type \c MeshKernel. It's quite a way to get a kernel . As long as the created kernel follows the kernel concept (\ref mesh_kernels_group), we can easily create now the mesh. Here we use now \c TriMeshT to create the final mesh type \c Mesh. */ //----------------------------------------------------------------------------- /** \page mesh_type Specifying your MyMesh This section will show how to build your own custom tailored type \c MyMesh. As we have seen in the section on goals and features there are some parameters to be specified for a mesh. This is done in the following four steps:
  1. Choose between triangle mesh and general polygonal mesh.
  2. Select the mesh kernel
  3. Parameterize the mesh by a so-called \em Traits class. You can add arbitrary classes to the mesh items, specify the types \c Scalar, \c Point, \c Normal and \c Color, and use predefined attributes like \c Attributes::Normal and \c Attributes::Color.
  4. Dynamically bind data to the mesh or the mesh entities (vertex, (half-)edge, face) using \em custom \em properties.
We will explain these four parameterization steps and give a code example at the end of this page.

\section sec_select_face_type Polygonal or Triangle Mesh? This decision is quite simple: Whenever possible choose the triangle mesh. The restriction to triangular faces usually leads to more efficient algorithms (e.g. rendering triangles is much faster than rendering arbitrary polygons). Additionally some algorithms are only implemented for triangle meshes while triangle meshes inherit the full functionality of polygonal meshes. For a list of them refer to the following links. \see OpenMesh::PolyMeshT \see OpenMesh::TriMeshT

\section sec_select_kernel Choosing the right kernel The mesh kernel specifies how the mesh entities (vertices, (half-)edges, faces) are internally stored. In fact the entities are kept in so-called properties. A property itself provides an array like interface. The kernel defines the corresponding handle types, i.e. the way items reference each other. Since the properties have an array like interface the handles are represented internally as indices. The default kernel is \c ArrayKernelT. Which is good for most situations. But depending on the application a different kernel would be better. E.g. the OpenSG integration has been realized be replacing the kernel by a custom kernel, since OpenSG provides already array like properties, which could be reused for the intergration. In case of a an OpenSG environment one might be better off using \c OSG_Kernel::ArrayKernelT. \see \ref mesh_kernels_group

\section sec_select_traits Mesh Traits While the last two sections only have chosen from a list of predefined meshes or kernels, respectively, we now come to the user-defined customization. The resulting mesh \c MyMesh will provide the following types:
  • The point and scalar type: \c MyMesh::Point and \c MyMesh::Scalar.
  • The mesh items: \c MyMesh::Vertex, \c MyMesh::Halfedge, \c MyMesh::Edge, \c MyMesh::Face.
  • The handle types: \c MyMesh::VertexHandle, \c MyMesh::HalfedgeHandle, \c MyMesh::EdgeHandle, \c MyMesh::FaceHandle.
While the handle types are fixed, the other types can be customized. Each mesh type (see \ref mesh_types_group) can be parameterized by a so-called \em traits class. Using this mechanism one can
  1. change the coordinate type \c MyMesh::Point and the resulting scalar type \c MyMesh::Scalar == \c MyMesh::Point::value_type,
  2. change the normal type \c MyMesh::Normal
  3. change the color type \c MyMesh::Color
  4. use predefined attributes like normal vector, color, texture coordinates, ... for the mesh items.
  5. add arbitrary classes to the mesh items.
All these customizations are encapsulated in one class \c MyTraits, that is used as template argument to the mesh, e.g. \code struct MyTraits { // your customization }; typedef PolyMesh_ArrayKernelT MyMesh; \endcode The rest of this section explains the construction of this traits class, its application to the mesh will be the topic of the next section. For each mesh entity one can control the predefined attributes to be attached by a traits class using some convenience macros, e.g. \c OpenMesh::VertexAttributes and \c OpenMesh::VertexTraits for vertices. The default traits class looks like this: \include traits0.cc Please note that for example \c VertexTraits is a define concealing a template declaration. The actual template class name is \c VertexT, which is further simplified to a specific type \c Vertex at a later stage during the construction of the mesh kernel. Because the traits classes always have to provide the template classes \c VertexT, \c HalfedgeT, \c EdgeT, \c FaceT, and the types \c Point, \c Normal, \c Color, and \c TexCoord one should derive this class from the default implementation \c DefaultTraits. In this case you will only have to define the classes or types you want to override or substitute.
\subsection sec_change_point Changing the Point type Changing the type that is used to store the point coordinates as well as the normal vectors can simply be done by defining this type in the traits class. The following code changes the coordinate type in order to use \c double instead of \c float. \include traits1.cc Using the OpenMesh::VectorT class you can easily plug in any scalar type for the use in point coordinates, e.g. some exact arithmetic. You can also exchange the whole class representing points as long as it provides the same interface as the OpenMesh::VectorT class.
\subsection sec_add_attributes Adding Predefined Attributes There are some pre-defined attributes that can be appended to the mesh items. These global attributes are defined in the namespace OpenMesh::Attributes. The advantage of these attributes is that they are registered at the items they are added to. Therefore algorithms can check for these attributes at run-time as well as at compile-time. This is important if you want to implement algorithms acting on different meshes, that may or may not have e.g. normal vectors per vertex/face. Adding these predefined attributes is quite simple. You provide an unsigned int in the traits class, whose bits control whether or not a certain attribute should be attached or not. If you want to add a normal vector to your vertices and faces, and also want to have color information for vertices, the code would look like this: \include traits5.cc Internally each mesh item contains an \c enum defining the integer \c Attributes (containing the bits of used attributes OR'ed together). From its set/unset bits you can see whether a certain attribute is used. OpenMesh provides the macro OM_Check_Attrib for doing this: \code if (OM_Check_Attrib(MyMesh::Vertex, Normal) do_something_with_normals(); \endcode These run-time checks may not be sufficient in some cases. You can also check for attributes at compile-time and instantiate the correct functions by using function overloading. The class \c GenProg::Bool2Type maps true/false information to two different types, \c Bool2Type and \c Bool2Type. An example that draws OpenGL normals if they are available would look like this: \include draw_normals.cc Especially the compile-time checking for attributes is extremely useful because it does not generate any unnecessary code and does not perform expensive tests at run-time. \see OpenMesh::DefaultTraits \see OpenMesh::Attributes \see OpenMesh::GenProg
\subsection sec_add_traits Adding User-Defined Elements You can also add arbitrary types/elements/methods to the mesh items by providing a corresponding traits class for these items. Adding some index to the \c Vertex class is easily done by \include traits2.cc The macro \c VertexTraits hides some ugly template stuff. In fact, it is defined as \code #define VertexTraits template struct VertexT : public Base \endcode hence the traits class actually looks like this: \include traits3.cc You have to keep this in mind when you want to define constructors for your vertex type or when you want to derive the vertex type from other classes. The template argument \c Base provides access to the mesh handles and to the \c Point and \c Scalar type by its member class \c Refs. Adding a \c MyMesh::FaceHandle to the vertex class can therefore be implemented like this: \include traits4.cc Adding elements to other mesh items works in the same manner.
\subsection sec_algo_traits Using traits defined by algorithms From version 0.10.3 on algorithms can define traits/attributes they require and the user can merge these traits into his own traits. A more elegant way is to use dynamic properites, which can be added/removed during runtime by the algorithm. This is the preferred way to attach custom data to the mesh. An example for an algorithm as well as the application using traits is given in \ref tutorial_06.

\section sec_properties Dynamic Properties From version 1.0 on %OpenMesh provides dynamic properties. Instead of using traits to bind data at compile time algorithms or the application can use dynamic properties. Similar to entities the properties are accessed and manipulated via handles. An example for an algorithm as well as the application using properties is given in \ref tutorial_03 and \ref tutorial_04.

\section sec_traits_example Final Implementation Example Consider an application where we just want to render triangle meshes. This means we will select the triangle mesh and the \c ArrayKernelT. Faces that are not triangles will automatically be tesselated into triangles. Because we only display meshes and do not dynamically add or remove items, we can just use the \c ArrayKernelT. All mesh-kernel combinations are predefined in the directory %OpenMesh/Mesh/Types. Refer to \ref mesh_types_group for a complete list of them. For our example we use the \c TriMesh_ArrayKernelT and parameterize it by our \c MyTraits class. We will need face and vertex normals and e.g. for color coding vertex curvature, i.e. vertex color. \include mymesh.cc That's it. */ //----------------------------------------------------------------------------- /** \page mesh_eigen Specifying an OpenMesh using Eigen3 vectors This section will show how to build your own custom mesh type using Eigen3 vectors for points, normals or other entities. First of all you need to include the Eigen header shipped with OpenMesh: \code #include \endcode This header contains the external functions and vector traits used by OpenMesh. Afterwards you can specify your mesh: \code struct EigenTraits : OpenMesh::DefaultTraits { using Point = Eigen::Vector3d; using Normal = Eigen::Vector3d; using TexCoord2D = Eigen::Vector2d; }; using EigenTriMesh = OpenMesh::TriMesh_ArrayKernelT; EigenTriMesh mesh; \endcode Now you can use mesh as any other OpenMesh while using Eigen vectors as the underlying data type. \note OpenMesh uses stl vectors for storing its data.

The following picture shows the (simplified) conceptual inheritance diagram for the %OpenMesh classes. \image html inheritance-simple.scaled.png The basis for all meshes is the corresponding \c MeshKernel, taking care of the internal storage of the mesh items (vertices, (half-)edges, faces). This kernel is inherited by the \c PolyMeshT, i.e. the general polygonal mesh, adding higher level functionality. For specialization purposes the class \c TriMeshT is derived from \c PolyMeshT and overrides some member functions or adds functions only suitable for pure triangle meshes. In most cases a class (e.g. \c PolyMeshT) gets the class it should derive from (e.g. the mesh kernel) as a template parameter. The documentation class OpenMesh::Concepts::MeshKernel::KernelT lists the minimal interface a mesh kernel must provide. Special kernels may provide some more functionality, in this case refer to this kernel's documentation (see \ref mesh_kernels_group). Therefore your mesh provides the pubic member functions of
  • The mesh kernel.
  • The general polygonal mesh.
  • The specialized triangle mesh (if you use a TriMesh instead of a PolyMesh).

The corresponding functions are defined in the namespace OpenMesh::MeshIO. This section is divided into three steps. Step one will give a short example on how to use the %OpenMesh IOManager, step two will give some background information on how IOManager works and finally step three will show you how to add your own modules to IOManager. A tutorial with more information regarding file IO can be found here: \ref tutorial_08 \section mesh_io_quick Step 1 - IOManager quick start For a quick start you can copy the following code directly to your project. \note
  • If you link statically against OpenMesh, you have to add the define OM_STATIC_BUILD to your application. This will ensure that readers and writers get initialized correctly.
  • IOManager uses the filename extension to determine which reader/writer to use. I.e. if passing "inputmesh.obj" as filename parameter, the OBJ-File reader/writer will be used to parse/write the file.
\include mesh_io.cc

\section mesh_io_theory Step 2 - The theory behind IOManager Usually mesh reader and writer routines are written directly against the data structure and the respective file format they support. This approach has the main disadvantage that targeting a different data structure or adding another file format leads to duplication of code. IOManager acts as an interface between persistent data on one side and an arbitrary data structure on the other side by means of reader/writer and importer/exporter modules. This is illustrated by the following diagramm : \image html iomanager.png
Persistent data of arbitrary format is first interpreted by a reader module. The data is then passed - by means of a specified interface - to an importer module for the target data structure. The process for writing data is analogous. The IOManager controls the entire process. Reader/Writer modules are invisible to the user. Importer/Exporter however have to be specified explicitely as they are specific to a data structure. The complete separation of data structure and persistent data makes it especially easy to maintain existing code and to extend funtionality at both ends as will be shown in step three. \see OpenMesh::IO::_IOManager_

\section mesh_io_extend Step 3 - How to extend IOManager \subsection mesh_io_extend_fileformat Adding support for a new file format Adding support for a new file format involves adding a reader and writer module. Reader modules are classes derived from OpenMesh::IO::BaseReader. The part of the interface that you usually have to define is shown below. \include BaseReader.hh Based on the file extension or the header information the IOManager decides which reader module to use. The reader then parses the format and the information will be passed to the target data structure be means of a class derived from OpenMesh::IO::BaseImporter. Writer modules are derived from OpenMesh::IO::BaseWriter and work the same way as reader modules.
\subsection mesh_io_extend_datastruct Adding support for a new data structure As we have already seen, Importers receive information from the reader modules. Reader modules pass information through a specified interface : \include BaseImporter.hh The Importer is then responsible for filling the target data structure. Exporting information from a data structure is a little bit more involved than importing data to it. The writer modules must be able to iterate over all vectors/texcoords/faces. Therefore an exporter has to provide these iterators : \include BaseExporter.hh There might be the need for the exporter to cache data from the structure it refers to. The update() function should be called at the beginning of each BaseWriter::save() method and it should make sure that cached information is up to date. For further information you are encouraged to take a look at the modules provided by %OpenMesh which can be found in the IO subdirectory. */ //----------------------------------------------------------------------------- /** \page mesh_iterators Mesh Iterators and Circulators - \ref it_iters - \ref it_iters_h - \ref it_iters_skipping - \ref it_circs - \ref it_circs_h \section it_iters Iterators The mesh provides linear iterators (that enumerate vertices, halfedges, edges, and faces). These can be used to easily navigate through a mesh. Each iterator \c XYZIter also exists in a const version \c ConstXYZIter. All iterators are defined in the namespace OpenMesh::Iterators. They are template classes that expect a mesh as template argument to be fully specified. You should use the iterator types provided by the mesh itself, i.e. \c MyMesh::VertexIter instead of \c OpenMesh::Iterators::VertexIterT. The iterators are: \include iterators.cc The corresponding \c const counterparts are \arg \c ConstVertexIter, \arg \c ConstHalfedgeIter, \arg \c ConstEdgeIter, \arg \c ConstFaceIter. The linear iterators are conformant to STL iterators. For a description of their interface see OpenMesh::Concepts::IteratorT. When using iterators, use the pre-increment operation (++it) for efficiency reasons. \deprecated While it is possible to use \c handle() to get the handle of the item referred to by the iterator, this function is deprecated. Simply dereference the iterator instead. \subsection deletedElements Deleted Elements If no elements of a mesh are marked as deleted, the indices provided by \c idx() are consecutive numbers from 0 to number of elements-1 (in the case of vertices this would be from 0 to n_vertices()-1). However, note that this is not the case when elements are marked as deleted and OpenMesh::ArrayKernel::garbage_collection() has not yet been called. After garbage_collection() has been called the elements are reorganized and their handles and iterators are guaranteed to be consecutive numbers again. OpenMesh uses a lazy deletion scheme to avoid unnecessary updates to the data structure. The halfedge data structure will always be updated directly to ensure that following algorithms will have the correct iterator setups. So if you delete a face, The face itself will still exist but the halfedges which are now located at the hole will be updated directly, which means that circulators on the adjacent vertices will not come across the face anymore. If an edge is deleted, the adjacent faces will be removed as well (flagging them deleted and updating the surrounding halfedges). The edge itself will also be flagged as deleted. Again the circulators will not see the deleted primitives anymore. For a vertex, all adjacent faces and edges are deleted with the schemes above and the vertex flagged as deleted. The iterators, going across vertices edges and faces will still enumerate all primitives (including deleted ones). Except if you use the skipping iterators, which will skip deleted primitives. The circulators always only enumerate primitives which are not deleted. \note
  • If you delete elements on the mesh, they will still be enumerated by the standard iterators. To skip deleted elements, use the \ref it_iters_skipping
  • An iterator to an item usually needs more memory than a handle of an item. To store many references to an item, it is therefore better to use handles.
\section it_iters_h How to use iterators in OpenMesh This example shows how to iterate over all faces of a mesh: \code MyMesh mesh; for(MyMesh::FaceIter f_it = mesh.faces_begin(); f_it != mesh.faces_end(); ++f_it) { std::cout << "The face's valence is " << mesh.valence( *f_it ) << std::endl; } \endcode \section it_iters_skipping Skipping Iterators All iterators are also available as skipping iterators. If elements are deleted on a mesh, the standard iterators go over all elements, even deleted ones(which are available until a garbage_collection is done). The skipping iterators ignore these elements. You can retrieve a skipping iterator by calling one of the following functions: \arg \c vertices_sbegin(), \arg \c edges_sbegin(), \arg \c halfedges_sbegin(), \arg \c faces_sbegin() The ends for these iterators are equal to the standard iterator ends (e.g. \c vertices_end() ). \section it_circs Circulators %OpenMesh also provides so called Circulators that provide means to enumerate items adjacent to another item of the same or another type. For example, a \c VertexVertexIter allows to enumerate all vertices immediately adjacent to a (center) vertex (i.e. it allows to enumerate the so-called 1-ring of the center vertex). Analogously, a \c FaceHalfedgeIter enumerates all the halfedges belonging to a face. In general, \c CenterItem_AuxiliaryInformation_TargetItem_Iter designates a circulator that enumerates all the target items around a given center item. The constructor of a circulator is of the form \c Circulator(MeshType mesh, TargetHandle center_handle), i.e. it takes a mesh and the handle of the item to circulate around. The circulators around a vertex are: \arg \c VertexVertexIter: iterate over all neighboring vertices. \arg \c VertexIHalfedgeIter: iterate over all \em incoming halfedges. \arg \c VertexOHalfedgeIter: iterate over all \em outgoing halfedges. \arg \c VertexEdgeIter: iterate over all incident edges. \arg \c VertexFaceIter: iterate over all adjacent faces. The circulators around a face are: \arg \c FaceVertexIter: iterate over the face's vertices. \arg \c FaceHalfedgeIter: iterate over the face's halfedges. \arg \c FaceEdgeIter: iterate over the face's edges. \arg \c FaceFaceIter: iterate over all edge-neighboring faces. The circulators around an edge are: \arg \c EdgeVertexIter: iterate over the edge's incident vertices. \arg \c EdgeHalfedgeIter: iterate over the edge's halfedges. \arg \c EdgeFaceIter: iterate over the edge's incident faces. Other circulators: \arg \c HalfedgeLoopIter: iterate over a sequence of Halfedges. (all Halfedges over a face or a hole) All circulators provide the operations listed in CirculatorT, which are basically the same as the iterator funtions. \note Circulators are similar to bidirectional iterators and therefore they have the bidirectional_iterator_tag. However, the bidirectional requires that the attribute OpenMesh::Attributes::PrevHalfedge is available. Otherwise it is just a forward iterator. \deprecated While it is possible to use \c operator \c bool(), which returns true, as long as the circulator hasn't reached the end of the sequence, this function is deprecated. Use the function \c is_valid() instead. %OpenMesh provides the following functions (defined in OpenMesh::PolyConnectivity) to get circulators around a specified center item: \include circulator_functions.cc Additionally to the normal circulators there exists some for each direction (clock-wise, counterclock-wise). Those circulators might be slower than the normal one, but the direction of circulation is guaranteed. You can get these types of circulators by adding the infix "ccw" or "cw" to the function used to request the circulator of an item after the underscore. Example: \code VertexVertexIter vvit = mesh.vv_iter(some_vertex_handle); // fastest (clock or counterclockwise) VertexVertexCWIter vvcwit = mesh.vv_cwiter(some_vertex_handle); // clockwise VertexVertexCCWIter vvccwit = mesh.vv_ccwiter(some_vertex_handle); // counter-clockwise \endcode It is also possible to convert a cw circulator to a ccw circulator and vice versa. For this purpose, each circulator provides a constructor taking the other circulator as input. If a cw circulator is converted, the ccw circulator points on the same element as the cw circulator pointed on, but the direction for the increment and decrement changed.\n The conversion is only valid for valid circulators. The resulting circulator from a invalid circulator is still invalid, but might behave in a fashion not expected by normal iterators. Example: \code VertexVertexCWIter vvcwit = mesh.vv_cwend(some_vertex_handle); VertexVertexCCWIter vvccwit = VertexVertexCCWIter(vvcwit); //conversion of an invalid circulator --vvcwit; //is valid now (if the range >= 1) ++vvccwit; //can still be invalid \endcode CW and CCW circulators requires that OpenMesh::Attributes::PrevHalfedge is available. \note For every circulator there also exists a constant version. To make use of these constant circulators just add the prefix
"Const" to the type specifier and add the prefix "c" to the function used to request the circulator of an item. Example:
\code ConstVertexVertexIter cvvit = mesh.cvv_iter(some_vertex_handle); \endcode \note When constructing Circulators from iterators, make sure you don't create a circulator of an deleted element(e.g. FaceVertexiter of a deleted Face), as this will lead to unpredictable behaviour. Using skipping iterators for iterating over the elements and creating circulators from them is safe as they don't contain deleted elements. \section it_circs_h How to use circulators in OpenMesh The following code example now shows how to enumerate the 1-ring of each vertex: \include circulators.cc Enumerating all halfedges adjacent to a certain face (the inner halfedges) is accomplished as follows: \code MyMesh mesh; ... // Assuming faceHandle contains the face handle of the target face MyMesh::FaceHalfedgeIter fh_it = mesh.fh_iter(faceHandle); for(; fh_it.is_valid(); ++fh_it) { std::cout << "Halfedge has handle " << *fh_it << std::endl; } \endcode */ //----------------------------------------------------------------------------- /** \defgroup mesh_property_handle_group Mesh Property Handles All custom properties are represented by the property handles.

It would be more convenient and less error-prone if we could store this data in the mesh and let %OpenMesh manage the data. It would be even more helpful if we could attach such properties dynamically to the mesh. Custom properties can be conveniently created and attached to meshes by creating an object of type OpenMesh::PropertyManager. A PropertyManager manages the lifetime of the property and provides read / write access to its values. You can use the typedefs VProp, HProp, EProp, FProp, and MProp in order to create a PropertyManager attached to vertices, halfedge, edges, faces and the mesh respectively. Each of these takes as template argument the type of the property value that is attached to each element (e.g., \p int, \p double, etc.). We differentiate between two kinds of properties. Named and temporary properties. Temporary properties are created by just providing the constructor with a mesh on which the property should be created. These properties will be removed as soon as the PropertyManager goes out of scope. If in addition to the mesh a property name is provided, a named property will be created which will stay alive even after the PropertyManager goes out of scope. If a PropertyManager is given a name of an already existing property, it will provide read and write access to the same property. Finally, an optional first parameter can be given containing a value that will be used to initialize the property for all elements if the property is freshly created (i.e. always for temporary properties, and only the first time a specific name is used). Here are a few examples of how to create and access mesh properties: \code // Add a temporary mesh property that stores a double value for every vertex auto temperature = OpenMesh::VProp(mesh); OpenMesh::VertexHandle vh = ...; temperature[vh] = 1.0; // The temperature property will be removed from the mesh when the handle reaches the end of the scope. // Obtain an existing property that stores a 2D vector for every halfedge // (or create that property if it does not exist already) and initilize it with the Vector(1,1)) auto uv = OpenMesh::HProp(mesh, "uv", OpenMesh::Vec2d(1,1)); OpenMesh::VertexHandle heh = ...; std::cout << temperature[heh][0] << " " << temperature[heh][1] << std::endl; // Obtain an existing mesh property (or create that property if it does not exist already) // containing a description string auto desc = OpenMesh::MProp(mesh, "desc"); *desc = "This is a very nice mesh."; \endcode --- ## Code Example In this example, we will store the \c cog value (see previous example) in a vertex property instead of keeping it in a separate array. To do so, we first add a (temporary) property of the desired element type (OpenMesh::VertexHandle) and value type (\c %MyMesh::Point) to the mesh: \dontinclude 03-properties/smooth.cc \skipline VProp Enough memory is allocated to hold as many values of \c %MyMesh::Point as there are vertices. All insert and delete operations on the mesh are synchronized with the attached properties. Once the property is created, we can use it to compute the centers of the neighborhood of each vertex: \skipline mesh.vertices \until cog[vh] /= valence \until } Finally, we set the new position for each vertex: \skipline mesh.vertices \until mesh.point \until } Below is the complete source code: \include 03-properties/smooth.cc --- ## Property Lifetime In the above example, we chose to use VProp without a name. This causes the created property to automatically be removed from the mesh as soon as we leave the scope of the associated handle variable \c cog. If, instead, a property is desired to survive its local scope, it should be created with a name. For example: \code auto face_area = OpenMesh::FProp(mesh, "face_area"); \endcode At a later time, we can access the same property by using the same name. If we want to make sure, that we access a property that has already been created earlier, we can use hasProperty() to test whether a mesh has the desired property: \code if (OpenMesh::hasProperty(mesh, "face_area")) { // Property exists. Do something with it. auto valley = OpenMesh::FProp(mesh, "face_area"); } else { // Property does not exist. Do something else. } \endcode --- ## Low-Level Property API The property managers VProp, HProp, EProp, FProp and MProp are the convenient high-level interface for creating and accessing mesh properties. Beneath these convenience functions, there is also a low-level property interface where handle and property lifetime must be managed manually. This interface is accessed through a mesh's add_property(), get_property(), remove_property(), and property() functions and several property handle classes (OpenMesh::VPropHandleT, OpenMesh::HPropHandleT, OpenMesh::EPropHandleT, OpenMesh::FPropHandleT, OpenMesh::MPropHandleT). --- */ OpenMesh-11.0.0/Doc/tutorial_06.docu0000660000174600017460000000620114556675336021177 0ustar gitlab-runnergitlab-runner/** \page tutorial_06 Using mesh attributes and traits this example shows how to change the data type for positions, normals, colors, and texture, In the previous tutorial (\ref tutorial_05) we learned to use standard properties by calling the appropriate \c request method. Unlike the custom properties, where the user specifies the data type by passing the type to the handle (e.g. \c MyMesh::FPropHandleT< int>), the data types of the standard properties are defined by so-called mesh traits. With traits we can customize and extend the mesh data structure. We can do this by changing two important features -# changing data type for positions, normals, colors, and texture coordinates -# extend mesh entities Vertex, Face, Edge, and Halfedge (see tutorial '\ref tutorial_07') Let's start. Every custom traits should derive from the default traits \dontinclude 06-attributes/attributes.cc \skipline struct MyTraits As mentioned, we can change the basic data types for the basic types \c MyMesh::Point, \c MyMesh::Normal, \c MyMesh::Color, and \c MyMesh::TexCoord. We can use the provided vector class or we use a different one from another library. Here we simply replace the default type \c OpenMesh::Vec3f (defined in the \c OpenMesh::DefaultTraits) for positions and normals with \c OpenMesh::Vec3d \skipline Vec3d \skipline Vec3d (In general it's better to have the same scalar type for the point and normal vector, for instance \c double in this case. Otherwise we have to cast quite a lot depending on the implementation of the vector class.) Be aware that these settings overwrite the ones of the parent traits class! As we usually derive from the DefaultTraits let's have a close look. Actually the struct \c OpenMesh::DefaultTraits is merely empty. It solely defines the types for \c Point, \c Normal, \c TexCoord, and \c Color and one attribute, that we used implicitly all the time: \skipline HalfedgeAttributes The attribute \c PrevHalfedge is different, as it does not control a property. Yet it has a great impact on the resulting mesh type, as it adds additional information to the halfedge structure. The impact is twofold: -# fast access to previous halfedge -# increase of memory consumption Using this feature depends highly on our needs. One situation where the previous halfedges are quite handy, is the mesh member function add_face(). The execution time for the member function drops dramatically, when the information about the previous halfedge is available. Usually we want to have this information. But if not, because we must save memory, we can easily remove it with \skipline HalfedgeAttributes Then we need 8 bytes less per edge, which can be quite a lot as one can derive from the Euler formula (\f$V-E+F=2 (1-g)\f$), that for a regular triangle meshes with genus \f$g=0\f$ the number of edges \f$E\f$ is approximately three times the number of vertices \f$V\f$: \f$ E \approx 3 \cdot V\f$.

For each program the first step is to define your type \c MyMesh. %OpenMesh supports general polygonal meshes (faces are polygons with varying number of vertices) as well as specialized triangle meshes (all faces are triangles). In this example we want to build a cube from six quadrangles, therefore we choose the polygonal mesh. %OpenMesh also supports different mesh kernels, specifying how all the vertices, edges, and faces are stored internally (see also \ref mesh_kernels_group). However, the storage must provide an array like interface. For the tutorial we use the supplied ArrayKernel. The predefined combinations of TriMesh/PolyMesh and the kernel are contained in \c %OpenMesh/src/OpenMesh/Core/Mesh, we use the PolyMesh_ArrayKernelT. \dontinclude build_cube.cc \skipline PolyMesh_ArrayKernel \skipline MyMesh Now since we have declared our type \c MyMesh, we only have to add 8 vertices and 6 quadrangles to build a cube. Adding a vertex is done using the add_vertex method. It gets a coordinate and returns a handle to the inserted vertex. We store all handles in an array, since we need them for specifying the faces. \skipline vhandle[0] \until vhandle[3]
In order to add a face to the mesh, we have to build a vector holding the handles to the face's vertices. This vector is passed to the \c add_face method. The following block will create a face from the first four vertices: \skipline face_vhandles \until add_face
The orientation of the face is defined by the order in which the vertices are given: If you look at the frontfacing side of the polygon, then the vertices are in counter-clockwise order. After creating all of the six faces, we want to write the resulting mesh to standard output. %OpenMesh provides some basic input/output methods in the namespace OpenMesh::IO: \skipline write_

Note that this is an old style of using properties. Nowadays you should use the OpenMesh::PropertyManager instead. When you want to add an additional properties you have to attach it to a primitive of the mesh. You can attach to verticies, halfedges, edges, faces or to the mesh itself. Use the add_property function: \code // for each vertex an extra double value OpenMesh::VPropHandleT< double > vprop_double; mesh.add_property( vprop_double ,"Vertex property name"); // for each halfedge an extra int value OpenMesh::HEPropHandleT< int > heprop_int; mesh.add_property( heprop_int ,"Halfedge property name"); // for each edge an extra float value OpenMesh::EPropHandleT< float > eprop_float; mesh.add_property( eprop_float ,"Edge property name"); // for each face an extra double value OpenMesh::FPropHandleT< double > fprop_double; mesh.add_property( fprop_double ,"Face property name"); // for the mesh an extra string OpenMesh::MPropHandleT< string > mprop_string; mesh.add_property( mprop_string , "Mesh property name "); \endcode Accessing to the property is available via the property function. This function gets the property handle (created above) and a handle (e.g. to a vertex or a face): \code // Write something to a face property: mesh->property( , ) = ; // E.g. for (f_it=mesh->faces_begin(); f_it!=mesh->faces_end() ; ++f_it) { mesh->property( fprop_double , *f_it ) = 0.0; } \endcode As you can attach properties to the mesh, you might want to add a property in one function and access it in another, where the handle is not yet available. You can retrieve the required handle in the following way (Note that the handles are accessed by their name and type): \code // Specify handle type (Double face handle in this case): OpenMesh::FPropHandleT< double > fprop_double; // Try to get handle with the given name. if ( !mesh_.get_property_handle(fprop_double,"Face property name") ) { std::cerr << "Unable to retrieve property! " << std::endl; return } // If we reach this point, we have a valid handle. \endcode The properties can be removed by calling remove_property: \code // Remove the property mesh->remove_property(fprop_double); \endcode A useful function to see all properties on the mesh is: \code // Print all available properties mesh->property_stats(); \endcode A useful class for handling properties and their lifetime is the OpenMesh::PropertyManager. */ OpenMesh-11.0.0/Doc/misc.docu0000660000174600017460000000211314556675336017760 0ustar gitlab-runnergitlab-runner//----------------------------------------------------------------------------- /** \page naming_conventions Naming Conventions The following naming conventions are used for the %OpenMesh code: Files: \li \c MyClass.cc for C++-Implementation of class \c MyClass \li \c MyClassT_impl.hh for Header only C++-Implementation of template class \c MyClass \li \c MyClass.hh for C++-Header of class \c MyClass Classes: \li Class names start with a capital letter: \c MyClass \li Class templates end with \c T: \c MyClassTemplateT Variables: \li One leading underscore for parameters in function-calls: \c _var \li One trailing underscore for member-variables: \c var_ \li Two trailing underscores for static member-variables: \c var__ Functions: \li Words are separated by underscores: \c my_function() Accessing members: \li To get the member \c xxx_ use const& xxx() const \li To set the member \c xxx_ use void set_xxx(arg) **/ //----------------------------------------------------------------------------- OpenMesh-11.0.0/Doc/tutorial_main.docu0000660000174600017460000000340214556675336021676 0ustar gitlab-runnergitlab-runner/** \page tutorial Tutorials (code examples) The %OpenMesh mesh library is a powerful tool for handling polygonal meshes.

In this tutorial we will introduce the %OpenMesh library by means of simple examples. The first one just builds a polygonal mesh representing a cube and writes the result to standard output. The following examples develop a simple mesh smoother: Recall that the immediate neighbors of a vertex are called the 1-ring of this vertex. It is well known that a polygonal mesh can be smoothed by repeatedly replacing each vertex' position by the center of gravity (cog) of its 1-ring. The basic smoother will \li read a polygonal mesh from standard input, \li compute the cog of the 1-ring of each vertex, \li replace each vertex' position by its cog and finally, \li write the mesh to standard output.

These functions are defined on a mesh and require as input a handle to an element of the mesh, such as VertexHandle or HalfedgeHandle. In the following example we iterate over all vertices of a triangle mesh and for each vertex we create a list of the vertices that lie opposite of the edges in the ring around the vertex: \code // iterate over vertices of the mesh for (auto vh : mesh.vertices()) { std::vector opposite_vertices; // iterate over all outgoing halfedges for (auto heh : mesh.voh_range(vh)) { // navigate to the opposite vertex and store it in the vector opposite_vertices.push_back(mesh.to_vertex_handle(mesh.next_halfedge_handle(mesh.opposite_halfedge_handle(mesh.next_halfedge_handle(heh))))); } } \endcode For a more concise way of navigating OpenMesh provides smart handles, OpenMesh::SmartVertexHandle, OpenMesh::SmartHalfedgeHandle, OpenMesh::SmartEdgeHandle, and OpenMesh::SmartFaceHandle. Smart handles are smart, because they know to which mesh they belong. This allows them to provide functions for navigating the mesh allowing us to write the above code much simpler: \code // iterate over vertices of the mesh for (auto vh : mesh.vertices()) { // iterate over all outgoing halfedges std::vector opposite_vertices; for (auto heh : vh.outgoing_halfedges()) { // navigate to the opposite vertex and store it in the vector opposite_vertices.push_back(heh.next().opp().next().to()); } } \endcode The ranges of OpenMesh that are returned by functions like voh_range() or outgoing_halfedges() all provide a few methods than can simplify some calculations (see OpenMesh::SmartRangeT). One example is the to_vector() method which convertes the range of elements into a vector containing the elements. All of these methods take a functor as argument (sometimes optional) which is called for each element of the range. With this, the above code can also be implemented like this: \code // iterate over vertices of the mesh for (auto vh : mesh.vertices()) { // create lambda that returns opposite vertex auto opposite_vertex = [](OpenMesh::SmartHalfedgeHandle heh) { return heh.next().opp().next().to(); }; // create vector containing all opposite vertices auto opposite_vertices = vh.outgoing_halfedges().to_vector(opposite_vertex); } \endcode --- ## Code Example In this example, we will use bi-laplacian smoothing on a mesh. We store the \c laplace vector which is the vector pointing from a vertex to the center of gravity of its neighboring vertices in a vertex property. \dontinclude 11-smart_handles/smooth.cc \skipline laplace \skipline laplace To compute the center of gravity, i.e. the average position, we use the avg() method of the range of 1-ring vertices and pass in a PropertyManager acting as functor returning the corresponding point of a vertex. \skipline points \until avg(points) Similarily we compute the update vector as the laplace of the freshly computed laplace vectors by simply exchanging the points property manager with the laplace property manager. \skipline Iterate \until bi_laplace Finally, we apply the update after damping it by a factor of -0.5. \skipline update points \until bi_laplace Below is the complete source code: \include 11-smart_handles/smooth.cc --- */ OpenMesh-11.0.0/Doc/tutorial_08.docu0000660000174600017460000001443414556675336021210 0ustar gitlab-runnergitlab-runner/** \page tutorial_08 Using IO::Options This example shows: - How to control the behaviour of \c Mesh::IO::read_mesh(), - How to control the behaviour of \c Mesh::IO::write_mesh(). The class \c OpenMesh::IO::Options can be used when reading/writing a mesh. It controls the behaviour of the reader/writer modules by means of enabled/disabled bits in a bitset. The class provides an interface for enabling, disabling and verifying the bits in the set. We distinguish between -# mode bits - control binary reading/writing - Options::Binary - Options::MSB - Options::LSB - Options::Swap (MSB|LSB) -# property bits - controls which standard properties to read/write - Options::VertexNormal - Options::VertexTexCoord - Options::VertexColor - Options::FaceNormal - Options::FaceColor - Options::FaceTexCoord - Options::ColorAlpha - Options::ColorFloat - Options::Custom These bits have different effects when reading or writing. The file format itself is selected by the extension of the filename. Please take into account, each mesh has to request the standard property before loading with the corresponding option. For instance, if you enable Options::VertexNormal, your mesh has to request vertex normals. Otherwise, they will not be written into the mesh. \note Face Tex Coords will not be saved as a property per face, but as a property per halfedge. Therefore, you have to request the "halfedge_texcoords2D" property The OBJ-reader can also read information about the textures in the *.mtl file, if available. These texture information (includes texturename and index) will be saved in the property of type: \code OpenMesh::MPropHandleT< std::map< int, std::string > > \endcode with the name: \code "TextureMapping" \endcode This property will be automatically created, if textures were found. There is no other option you have to define for reading texture information beside of the request of the property.\n Additionally, the OBJ loader writes the texture index per face, if the property "face_texture_index" is requested. The texture index is the same index as the index written in the texture mapping. So, it is possible to get the name of the texture from a face via its texture index over the texture mapping property to the texture name. But remember, you have to request the face texture index property first before loading the mesh. Below in the table you can see what options are suported by which reader/writer (it is possible that the data format can support more). ASCII is not a real option and will be selected, if binary was not defined.

Take into account, that you don't have to request these custom properties before loading. \***) no reader exists The program does not more than providing a command line based interface to select the option bits for reading/writing and to request mesh properties. Hence illegal combinations are possible and will result in a failure of the program. (The input file won't be damaged in this case, but be careful where you put the ouput file!)
Reading meshes
When reading a file the mode bits are used to give the reader an advice or hint. Depending on the format we can help the reader to interpret the data correctly. First of all we can tell it that the file contains binary data. \dontinclude 08-io_options/io_options.cc \skipline ropt += IO::Options::Binary Further on we can ask the reader two swap the byte-order. \skipline ropt += IO::Options::Swap (Both can be done via the command line with the options -b and -s, respectively.) By default the geometry and the topology is restored from the file. The file might contain more, especially it could provide normals or texture coordinates. We can examine the property bits after reading to find out what else is available: \dontinclude 08-io_options/io_options.cc \skipline ropt.check(IO::Options::VertexNormal) If a property bit is set it does not mean, that it has been restored as well. The property must have been requested prior reading the file. (The demo program offers the command line option \c -Xv[nct] and \c -Xf[nc] to request vertex and face properties.)
Writing meshes
When writing the mesh the mode bits apparently control whether to use the binary variant and the desired byte-ordering. For example, if we choose binary mode and want to swap the byte order, we set \skipline wopt += IO::Options::Binary \skipline wopt += IO::Options::Swap If the format does not specify the byte order the system byte order is used. If the format does not support binary storage, the mode bits are ignored. If the format supports storing additional information, which are conform with the standard properties, we can use the property bits to tell the writer what we would like to have stored. If we would like to store the vertex normals we simply set \skipline wopt += IO::Options::VertexNormal Finally we can write the data to the file \dontinclude 08-io_options/io_options.cc \skipline write_mesh The method returns false on error, which might have three different reasons: -# the option is not supported by the choosen format -# a selected standard property is not available -# a 'system' error like - could not open the file due to access rights - disk space exhausted during write - ...

Similary we can use the defines \c FaceTraits, \c EdgeTraits, and \c HalfedgeTraits to extend these entities. Now we enhanced the vertex, with the additional member variable \c cog_, and the get/set-method pair to access the new member. As before we compute in a first loop the barycenters for all vertices and store the information at the vertices \skipline mesh.data(*v_it).set_cog In the second pass we set the new position of each vertex \skipline mesh.data(*v_it).cog It looks neat, but on the other hand we can't remove the data anymore as we could do with properties! By using traits one creates a 'static' configuration, which can't be changed during runtime.

You can download the HTML help workshop from the web # archives at Installation executable (see: # http://web.archive.org/web/20160201063255/http://download.microsoft.com/downlo # ad/0/A/9/0A939EF6-E31C-430F-A3DF-DFAE7960D564/htmlhelp.exe). # # The HTML Help Workshop contains a compiler that can convert all HTML output # generated by doxygen into a single compiled HTML file (.chm). Compiled HTML # files are now used as the Windows 98 help format, and will replace the old # Windows help format (.hlp) on all Windows platforms in the future. Compressed # HTML files also contain an index, a table of contents, and you can search for # words in the documentation.

The # DISABLE_INDEX tag can be used to turn on/off the condensed index (tabs) at top # of each HTML page. A value of NO enables the index and the value YES disables # it. Since the tabs in the index contain the same information as the navigation # tree, you can set this option to YES if you also set GENERATE_TREEVIEW to YES. # The default value is: NO. # This tag requires that the tag GENERATE_HTML is set to YES. DISABLE_INDEX = NO # The GENERATE_TREEVIEW tag is used to specify whether a tree-like index # structure should be generated to display hierarchical information. If the tag # value is set to YES, a side panel will be generated containing a tree-like # index structure (just like the one that is generated for HTML Help). For this # to work a browser that supports JavaScript, DHTML, CSS and frames is required # (i.e. any modern browser). Windows users are probably better off using the # HTML help feature. Via custom style sheets (see HTML_EXTRA_STYLESHEET) one can # further fine tune the look of the index (see "Fine-tuning the output"). As an # example, the default style sheet generated by doxygen has an example that # shows how to put an image at the root of the tree instead of the PROJECT_NAME. # Since the tree basically has the same information as the tab index, you could # consider setting DISABLE_INDEX to YES when enabling this option. # The default value is: NO. # This tag requires that the tag GENERATE_HTML is set to YES.

The default value points to the MathJax # Content Delivery Network so you can quickly see the result without installing # MathJax. However, it is strongly recommended to install a local copy of # MathJax from https://www.mathjax.org before deployment.
