	History

$Log: not supported by cvs2svn $
Revision 1.16  2008/04/03 23:15:40  cignoni
added optional mark and cleaned up some nasty type bugs.

Revision 1.15  2008/03/17 11:39:15  ganovelli
added curvature and curvatruredir (compiled .net 2005 and gcc)

Revision 1.14  2008/03/11 09:22:07  cignoni
Completed the garbage collecting functions CompactVertexVector and CompactFaceVector.

Revision 1.13  2008/02/05 20:42:43  cignoni
Other small typos

Revision 1.12  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 1.11  2007/12/11 18:25:31  cignoni
added missing include limits

Revision 1.10  2007/12/11 11:36:03  cignoni
Added the CompactVertexVector garbage collecting function.

Revision 1.9  2006/12/11 23:42:00  ganovelli
bug Index()() instead of Index()

Revision 1.8  2006/12/04 11:17:42  ganovelli
added forward declaration of TriMesh

Revision 1.7  2006/11/07 17:22:52  cignoni
many gcc compiling issues

Revision 1.6  2006/11/07 15:13:57  zifnab1974
Necessary changes for compilation with gcc 3.4.6. Especially the hash function is a problem

Revision 1.5  2006/11/07 11:29:24  cignoni
Corrected some errors in the reflections Has*** functions

Revision 1.4  2006/10/31 16:02:59  ganovelli
vesione 2005 compliant

Revision 1.3  2006/02/28 11:59:55  ponchio
g++ compliance:

begin() -> (*this).begin() and for end(), size(), Base(), Index()

Revision 1.2  2005/12/12 11:17:32  cignoni
Corrected update function, now only the needed simplexes should be updated.

Revision 1.1  2005/10/14 15:07:59  cignoni
First Really Working version
