[ODE] Trimesh vs Convex Hull

[Mohsin Hasan]

I would definitely say go for it. Its going into unstable so no worries
about it being incomplete. Whoever finds time will be able to look at the
code and hopefully contribute towards it. I would suggest you put links to
any reference research articles/papers directly in the comments of the code
(header file) so anyone interested in implementing it can have a good
starting point.

|I have some ongoing work to that effect, you'll notice the functions for
|drawing convex hulls are already in the drawstuff library.
|Currently, convex-sphere and convex-plane collision work, but I have had
|difficulties getting convex-convex collision working,
|plus, its been a while since I even looked at the code, I've been
|thinking about commiting what I have into unstable, for 2 reasons,
|the first one, because I think I am on the right track but short of
|time, someone may be able to lend a hand and the second,
|because with all the revisions, it sometimes gets hard to bring my work
|up to date with the latest version on CVS/SVN.
|
|So, what do you guys think? should I add the code already?
