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.
