Revision 1.12 2006/02/06 13:11:01 corsini
Renamed UnexpectedEOF as InvalidFile and
added UnsupportedFormat and ErrorNotTriangularFace (by Laurent Saboret)
Revision 1.11 2006/01/30 15:02:50 cignoni
Added mask filling in open
Revision 1.10 2006/01/10 13:20:42 cignoni
Changed ply::PlyMask to io::Mask
Revision 1.9 2005/12/01 00:58:56 cignoni
Added and removed typenames for gcc compiling...
Revision 1.8 2005/11/12 18:12:16 cignoni
Added casts and changed integral types to remove warnings
Revision 1.7 2005/09/28 10:30:14 rita_borgo
*** empty log message ***
Revision 1.6 2005/01/26 22:44:51 cignoni
Resolved scoping of constant of OFF codes
Revision 1.5 2005/01/18 12:35:18 rita_borgo
Added #include<vcg/complex/trimesh/allocate.h>
it was giving problems with Allocator::
Revision 1.4 2005/01/03 11:18:24 cignoni
changed a .. rfind('OFF') .. in rfind("OFF") and added some casts
Revision 1.3 2004/11/23 11:56:50 cignoni
Corrected small bug in the tokenizer (it would add a fake token for lines ending with a space before /n)
