V3dconverter is a command line tool to convert *.obj and *.ac file formats to/from *.3d format.
Only *.obj to *.3d conversion is fully operational, *.3d to *.obj and *.ac to *.3d are very experimental at now.

…has textured AND untextured faces.

In obj to v3d conversion: don't translate obj 's' (smoothing group) statement into V3d shade_model_* statement because V3d supports only one shade_model_* per file.
In experimental v3d to obj conversion: v3dconverter-generated *.3d objects are now read correctly (TEXCOORD keyword was missing).
In experimental v3d to obj conversion: primitives counter gives now correct result.

- better *.obj to *.3d face normals conversion.
- remove 'type 1' when writing *.3d file because 'type' parameter is deprecated and not used in Sar2.
- usefull informations are now written at *.3d top of file (and not only at console).
- add model rectangular/circular/spherical bounding box volume information, which can help to decide which contact detection shape is the best (lower is better...).
