$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)
