$Log: not supported by cvs2svn $
|
|
Revision 1.12 2008/03/17 11:39:14 ganovelli
|
|
added curvature and curvatruredir (compiled .net 2005 and gcc)
|
|
|
|
Revision 1.11 2008/02/04 21:26:49 ganovelli
|
|
added ImportLocal which imports all local attributes into vertexplus and faceplus.
|
|
A local attribute is everything (N(), C(), Q()....) except pointers to other simplices
|
|
(i.e. FFAdj, VFAdj, VertexRef) which are set to NULL.
|
|
Added some function for const attributes
|
|
|
|
Revision 1.10 2007/03/12 15:37:21 tarini
|
|
Texture coord name change! "TCoord" and "Texture" are BAD. "TexCoord" is GOOD.
|
|
|
|
Revision 1.9 2007/02/12 19:00:56 ganovelli
|
|
added Name(std:vector<std::string>& n) that fills n with the names of the attribute of the vertex type
|
|
|
|
Revision 1.8 2006/09/28 17:34:11 cignoni
|
|
Added Missing GetBBox function
|
|
|
|
Revision 1.7 2006/02/27 17:42:43 ponchio
|
|
Added some documentation.
|
|
|
|
Revision 1.6 2005/12/05 15:58:10 cignoni
|
|
Removed spurious definition of flags in Aritymax that was overriding the correct definition in EmplyBitFlags and BitFlags classes
|
|
|
|
Revision 1.5 2005/12/02 00:44:41 cignoni
|
|
Reformatted and compacted flags code.
|
|
|
|
Revision 1.4 2005/11/16 22:59:35 cignoni
|
|
Standardized name of flags. It is plural becouse each simplex has many flag.
|
|
|
|
Revision 1.3 2005/11/12 18:36:51 cignoni
|
|
Added 'Visited' flag functions
|
|
|
|
Revision 1.2 2004/04/03 13:33:55 cignoni
|
|
Missing include
|
|
|
|
Revision 1.1 2004/03/29 08:36:26 cignoni
|
|
First working version!

These are the three main classes that are used by the library user to define its own vertexes.
|
|
The user MUST specify the names of all the type involved in a generic complex.
|
|
so for example when defining a vertex of a trimesh you must know the name of the type of the edge and of the face.
|
|
Typical usage example:
|
|
|
|
A vertex with coords, flags and normal for use in a standard trimesh:
|
|
|
|
class VertexNf : public VertexSimp2< VertexNf, EdgeProto, FaceProto, vert::Coord3d, vert::Flag, vert::Normal3f > {};
|
|
|
|
|
|
A vertex with coords, and normal for use in a tetrahedral mesh AND in a standard trimesh:
|
|
|
|
class TetraVertex : public VertexSimp3< TetraVertex, EdgeProto, FaceProto, TetraProto, vert::Coord3d, vert::Normal3f > {};
|
|
|
|
|
|
A summary of the available vertex attributes (see component.h for more details):
|
|
|
|
Coord3f, Coord3d,
|
|
Normal3s, Normal3f, Normal3d
|
|
Mark //a int component (incremental mark)
|
|
BitFlags
|
|
TexCoord2s, TexCoord2f, TexCoord2d
|
|
Color4b
|
|
Qualitys, Qualityf, Qualityd
|
|
VFAdj //topology (vertex->face adjacency)
