Revision 1.34 2008/05/16 10:07:36 ganovelli
added Trimesh destructor to purge unremoved PerVertex[PerFace]Attribute
Revision 1.33 2008/05/15 16:32:27 ganovelli
PerVertexAttribute and PerFaceAttribute added to Trimesh
Revision 1.32 2008/04/15 10:34:07 cignoni

Corrected some errors in the reflections Has*** functions
Revision 1.23 2006/10/27 11:08:18 ganovelli
added override to HasFFAdjacency , HasVFAdjacency for the optional attributes (see also complex/trimesh/allocate.h)
Revision 1.22 2006/07/10 14:26:22 cignoni
Minor. Added a disambiguating this at the constructor of trimesh
Revision 1.21 2006/05/25 04:40:57 cignoni
Updated HasPerFaceColor/Quality to the new style with mesh param.
Revision 1.20 2006/05/03 21:35:31 cignoni
