HI I''m tryng to make a 3ds file loader. Can anyone explain to me, how the u,v coords work? I know it has something to do with the texture mapping coordinates, but i don''t understand... sohouldn''t be 4 coords? There is also a translation and a rotation matrix for each object.. should i apply this transformations when i render the final object to the screen? thanks Bruno

Well from what I understand u,v coordinates are coordinates on the texture you would use. You take these coords and supply this 2d coordinate after or before you specify the vertex the coincides with it. It may be totally different but maybe this idea will help. Look at the glTexCoord2f(); command.
