HGE

I'm not sure about those model types you mentioned, though I imagine you can find plenty of information about them on the web, as there are many quake map & model loaders kicking around. Failing that the GPLed Quake I/II/III source code is available on id's website.

You could also try this NeHe tutorial. Although the graphics API is OpenGL the model loading code is the same. I think there's an updated version of the loader code somewhere that fixes a few things. If you can't find it I have a copy sitting around somewhere.

Also, HGE doesn't have any 3D support at all. So I don't think you're going to have much luck animating 3D models in HGE. If you mean rendering the animations to textures and using those as sprites, then you'll need a 3D modeling package to do the rendering.

I want to use Q3 models in my project.
I have rewrote a little HGE core, so I can include ortho or a perspective projection.
I need sources only for loading, render and using 3d animation.
