$Log: not supported by cvs2svn $
Revision 1.11 2007/05/04 16:34:31 ganovelli
changes to comply "plus" types
Revision 1.10 2006/05/21 07:00:01 cignoni
Removed not working Equalized color (use funcs in stat.h)
Revision 1.9 2006/03/01 10:29:55 ponchio
HACK: MaxVal(0.0f) not defined in vcg/math/base.h as it should be,
changing it to 1e36 (pretty close :P)
Revision 1.8 2005/12/19 16:47:42 cignoni
Better comment and a parameter more for UpdateColor::VertexBorderFlag
Revision 1.7 2005/08/08 10:28:13 ganovelli
added math:: namespace before min and max
Revision 1.6 2004/08/25 15:15:26 ganovelli
minor changes to comply gcc compiler (typename's and stuff)
Revision 1.5 2004/07/15 00:13:39 cignoni
Better doxigen documentation
Revision 1.4 2004/06/24 07:56:54 cignoni
now use std::numeric_limits instead of old max val()
Revision 1.3 2004/03/12 15:22:19 cignoni
Written some documentation and added to the trimes doxygen module
Revision 1.2 2004/03/10 00:48:06 cignoni
changed to the face::IsBorder() style
Revision 1.1 2004/03/05 10:59:24 cignoni
Changed name from plural to singular (normals->normal)
