$Log: not supported by cvs2svn $
Revision 1.7 2006/01/09 13:58:55 cignoni
Added Initialization of Color in Vertex and Face Components
Revision 1.6 2005/11/22 15:49:39 cignoni
removed two spurious computenormal
Revision 1.5 2005/11/21 21:44:47 cignoni
Moved ComputeNormal and ComputeNormalizedNormal out of the face class (no more a member function!)
Revision 1.4 2005/11/18 15:44:49 cignoni
Access to constant normal changed from by val to by reference
Revision 1.3 2005/11/16 22:58:17 cignoni
Added IncrementalMark and WedgeTexCoord
Standardized name of flags. It is plural becouse each simplex has many flag.
Revision 1.2 2005/11/12 18:43:14 cignoni
added missing cFFi
Revision 1.1 2005/10/14 15:07:58 cignoni
First Really Working version
