Getting started with 3D model formats

Brief tutorial that should get you started, based on what I did.
Provides very informal (and possibly wrong) explanations for all the technical concepts. Is meant for you to get an idea what you're getting yourself into, rather than information.

You should go and read better explanations on wikipedia or other formal sources.
Or you can just read this; it's much more formal and accurate:
