I have heard of two types of model animation. Heirchal(probably spelled wrong), and bone systems. What are the spicifics of each one?(The differences) Which one is easier to implement? And which one is faster? I want to make my own model format and need some info on how to go about it.

Well as far as I know, there''re more than those 2:

Hierachal Animation is the same as skeletal animation (or?)
It basically works like this:

you''ve got a tree (= hierachel) structure with bones or joints at each node.. then you save an matrix for each keyframe (you don''t need keyframing, but it''s kinda cool). there''s a tutorial here about hierachel (written wrong ;o) structures and how to handle them....

another method would be to save an extra geometry model for each frame, which costs a lot of memory, but is very fast cause you can put them into display lists in Opengl..

Just my thoughts..
