Is anyone know a good 3ds file loader for opengl including animation or else, documentation in order to code one ?
I am aware of several libraries that will parse 3DS files.
lib3DS (www.sourceforge.net) and the 3DSFTK (see the links page on my web site) are probably the most common.
Both libraries will parse 3DS files; however, you will need to write the code that renders the object.
I have never used lib3DS, but I have found the 3DSFTK to be useful. The data structures are documented and easy to interpret. The documentation is poorly formatted, but you can decipher it.
