I’ve recently been working in Papervision3D with some MD2 avatars. Since the MD2 format was originally designed for Quake II, I figured there were no better models to use than the actual game models. I’ll be releasing the code in a thorough tutorial on how to accomplish this, but in the meantime, you can see the Quake Model Viewer in action.
I’ve tied in the original sounds to the avatar actions, and the two player avatars have separate weapon models that work seamlessly within the viewer. I plan on rolling in some further improvements before releasing the full tutorial.
