Following on from the discussion here, someone mentioned that some 3d file formats are poorly documented and suggested that if a game developer can give a better answer than a programmer (on say StackOverflow) then the answer should be found here.
From my experience, 3D file format parsing is quite difficult, but the reality is that most formats are easily parsed using assimp, which in itself is quite a beast. I was recently trying to extract some skeletal animation from a collada (dae) file built using 3DS max and exported with it too. I had to parse the bone structure, along with the animations structure, and the answer on Gamedev.stackexchange.com was pretty much my go-to for the entire project.
What I would suggest is keeping a community wiki style answer, with a few explanations similar to the last one mentioned, and pointing new users towards it?
