I couldn't find any information on how to do 3D collision detection
with google. I hope someone here can figure out how to do a
cylinder (or sphere, if easier) collision detection with a triangle
mesh.
This PDF is one of the clearer examples I've come across: <http://
www.peroxide.dk/papers/collision/collision.pdf>. Stair climbing is
basically automatic when using this technique, and ellipses are
flexible volumes - nearly as good as cylinders, but use way cheaper
math.
I had some success implementing an older non-swept sphere version of
this in RB (even released a precompiled test/demo here on the list)
but the code was kinda experimental/brutal so I kinda just let it
die, hoping in time to redo things properly with swept collision - no
time for that yet unfortunately!
