$Log: not supported by cvs2svn $
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

Note
OCF = Optional Component Fast (hopefully)
compare with OCC(Optional Component Compact)
Mainly the trick here is to store a base pointer in each simplex...
