  History

$Log: not supported by cvs2svn $
Revision 1.20  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 1.19  2006/12/11 23:40:57  ganovelli
Has*Opt migrated to Has*Occ

Revision 1.18  2006/11/28 22:34:28  cignoni
Added default constructor with null initialization to adjacency members.
AddFaces and AddVertices NEED to know if the topology is correctly computed to update it.

Revision 1.17  2006/01/09 13:58:56  cignoni
Added Initialization of Color in Vertex and Face Components

Revision 1.16  2005/11/22 23:58:03  cignoni
Added intiailization of flags to zero in the constructor,

Revision 1.15  2005/11/18 15:44:51  cignoni
Access to constant normal changed from by val to by reference

Revision 1.14  2005/11/16 23:02:37  cignoni
Added some missing members to EmptyMark
Standardized name of flags. It is plural becouse each simplex has many flag.

Revision 1.13  2005/11/14 23:50:57  cignoni
Added Incremental Mark

Revision 1.12  2005/11/12 18:35:49  cignoni
Changed HasFlag -> HasFlags

Revision 1.11  2005/11/01 18:17:52  cignoni
Added an assert(0) in all the accesses to empty components

Revision 1.10  2005/10/15 16:24:10  ganovelli
Working release (compilata solo su MSVC), component_occ <EFBFBD> migrato da component_opt

Revision 1.9  2005/10/14 13:30:07  cignoni
Added constant access functions and reflective functions (HasSomething stuff)
to all the components This is the first really working version...

Revision 1.8  2005/10/07 15:19:54  cignoni
minor updates to keep it in line with the rest of the library

Revision 1.7  2004/05/10 13:50:32  cignoni
Updated names of adj functions to the new standards

Revision 1.6  2004/04/05 11:53:06  cignoni
addend constant access funcs

Revision 1.5  2004/04/03 13:35:51  cignoni
minor changes

Revision 1.4  2004/03/31 13:15:28  cignoni
Added optional cpmponent

Revision 1.3  2004/03/31 12:28:37  ganovelli
*** empty log message ***

Revision 1.2  2004/03/29 14:26:38  cignoni
Error in color

Revision 1.1  2004/03/29 08:36:26  cignoni
First working version!
