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 1.10 2007/03/12 15:37:21 tarini Texture coord name change! "TCoord" and "Texture" are BAD. "TexCoord" is GOOD. Revision 1.9 2007/02/12 19:00:56 ganovelli added Name(std:vector& n) that fills n with the names of the attribute of the vertex type Revision 1.8 2006/09/28 17:34:11 cignoni Added Missing GetBBox function Revision 1.7 2006/02/27 17:42:43 ponchio Added some documentation. Revision 1.6 2005/12/05 15:58:10 cignoni Removed spurious definition of flags in Aritymax that was overriding the correct definition in EmplyBitFlags and BitFlags classes Revision 1.5 2005/12/02 00:44:41 cignoni Reformatted and compacted flags code. Revision 1.4 2005/11/16 22:59:35 cignoni Standardized name of flags. It is plural becouse each simplex has many flag. Revision 1.3 2005/11/12 18:36:51 cignoni Added 'Visited' flag functions Revision 1.2 2004/04/03 13:33:55 cignoni Missing include Revision 1.1 2004/03/29 08:36:26 cignoni First working version! ****************************************************************************/ #ifndef __VCG_VERTEX_PLUS #define __VCG_VERTEX_PLUS //#include #include #include #include #include namespace vcg { /*------------------------------------------------------------------*/ /* The base class of all the recusive definition chain.
