Supports 26 graphic formats. Good utility with full source for reading .3DS files. It's also done well enough that adding support for more features of the .3ds format should not be that difficult from a coding standpoint.
Specs are admittedly hard to find.
This program is a little utility to convert 3D files to a number of other 3D formats. It can generate smooth triangles for those formats that support it, allowing you to specify the angle under which the faces should be smoothed. No-compromises code optimized for both conversion quality and speed. It can shrink and enlarge graphics. The BitmapShrinker tries to choose the best fitting colors for the pixels in the resulting graphic to avoid disturbing stair and block-effects.
