$Log: not supported by cvs2svn $
Revision 1.6  2006/11/04 14:01:00  granzuglia
fixed bug: &(*filename.end()) ---> &(*filename.rbegin())

Revision 1.5  2006/07/09 05:32:15  cignoni
Uncommented obj export. Now obj saving is enabled by default

Revision 1.4  2006/03/29 08:14:20  corsini
Add LoadMask to OFF importer

Revision 1.3  2006/02/16 19:28:36  fmazzant
transfer of Export_3ds.h, Export_obj.h, Io_3ds_obj_material.h from Meshlab to vcg

Revision 1.2  2006/01/13 15:47:42  cignoni
Uniformed return type to the style of Open. Now every export function returns 0 in case of success.

Revision 1.1  2005/11/12 18:34:17  cignoni
Initial Commit
