$Log: not supported by cvs2svn $
Revision 1.27 2006/05/03 21:21:21 cignoni
Corrected bug: mismatch in the index of confidence vertex property (8 instead of 11)
Changed HasPerFaceColor to the new syntax (HasPerFaceColor(m) instead of FaceType::HasFaceColor() )
Revision 1.26 2006/02/03 09:46:24 corsini
Remove signed/unsigned warning
Revision 1.25 2006/01/11 10:37:12 cignoni
Removed warning for unused vars
Revision 1.24 2006/01/10 13:20:42 cignoni
Changed ply::PlyMask to io::Mask
Revision 1.23 2006/01/04 16:17:03 cignoni
Corrected use of mask and callback in function Open(m,filename,mask,callback);
Revision 1.22 2005/12/30 22:30:43 cignoni
Added support for per vertex color stored as 'diffuse_xxx' property
Revision 1.21 2005/12/02 10:04:18 cignoni
forgotten a couple of std::
Revision 1.20 2005/12/02 00:01:30 cignoni
Added loading of texturenames (normalmap still to do)
Revision 1.19 2005/11/25 10:23:27 cignoni
Added safe zero initialization of index of wedge texture
Revision 1.18 2005/11/23 16:59:55 callieri
corrected protected access methods (camera, similarity) of shot
Revision 1.17 2005/11/12 18:13:30 cignoni
Added support for non triangular faces (simple fan triangulation) and removed flags intiailization.
Revision 1.16 2005/10/14 15:09:56 cignoni
Added LoadMask without plyinfo and some comment on the mask usage
Revision 1.15 2005/06/10 15:05:00 cignoni
Made inline PlyType specializations
Revision 1.14 2005/04/14 15:09:38 ponchio
New gcc 3.3.3 (with bugs and features) now compiles.
Revision 1.13 2005/03/18 00:14:39 cignoni
removed small gcc compiling issues
Revision 1.12 2005/02/08 17:28:22 tarini
changed 120 "const static" to "static const", and added missing "format" fields to all PropDescriptor literals, to keep Mingw compiler happy
Revision 1.11 2005/01/03 10:35:47 cignoni
Improved the compatibility for ply format for faces having the list size (e.g. number of vertexes of a face) as a char instead of a uchar.
Added a couple of new face descriptors, corrected a bug in error reporting function (and restructured) and translated a few comments.
Thanks to Patrick Min for the careful bug reporting
Revision 1.10 2004/10/07 14:51:10 ganovelli
added setidentity della camera
Revision 1.9 2004/10/07 14:19:06 ganovelli
shot/camera io added
Revision 1.8 2004/06/23 15:36:43 cignoni
Restructured management of error, now the standard open for any mesh type return the error code, the default success value is zero
Any import class has a method ErrorMsg that give a verbal description of an error code.
Revision 1.7 2004/06/11 17:09:41 ganovelli
inclusion of vector..minorchanges
