|
|
|
|
Revision 1.32 2007/02/02 00:29:33 tarini
|
|
added a few typecasts to QualityTypefor vertices and faces (avoids warinings when short int or int is used for Quality).
|
|
|
|
Revision 1.31 2006/12/18 09:46:39 callieri
|
|
camera+shot revamp: changed field names to something with more sense, cleaning of various functions, correction of minor bugs/incongruences, removal of the infamous reference in shot.
|
|
|
|
Revision 1.30 2006/11/27 10:36:13 cignoni
|
|
Removed flags initialization. no more necessary
|
|
|
|
Revision 1.29 2006/10/14 00:18:42 cignoni
|
|
Allowed the correct loading of meshes with 0 faces
|
|
|
|
Revision 1.28 2006/05/16 15:01:30 cignoni
|
|
Wedge colors are loaded into facecolor only if specified in the incoming pi.mask
|
|
|
|
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
|
|

|
|
|
|
Revision 1.16 2005/10/14 15:09:56 cignoni

|
|
|
|
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
