- Actually we've been using bounding volumes [ Boxes or Spheres ] that
- approximate the objects shape and interaction with the world. We're not
- simulating feet moving around and as such we don't need super accuracy. Mostly
- aircraft, vehicles , terrain and such. I imagine there is a way you could
- assemble multiple bounding volumes in a heirarchy for each object's respective
- components to make interaction calculations a bit finer....bla bla bla ....
