[ODE] Tri-collider page on wiki

Yeah, I'm hanging out for movable trilists as well. Calculating the inertia
tensor separately doesn't scare me too much :)

Thanks Norman. This is very helpful.

Under "Limitations of the Triangle Collider" I see--
#  Current tri-collider code might not yet support moving tri-meshes (the
transformation matrix for the tri-mesh must be identity, see mailing list)
# Once moving tri-meshes are supported, you still need external library to
compute arbitrary inertia tensor for moveable tri-meshes

What I'm interested in is a tri-list that responds to dGeomSetPosition() and
dGeomSetRotation().  My tri-list geom is linked to a scene graph and I'd
like to follow the scene graph node as it moves/rotates.

I don't need inertia or a body yet.  Just teleporting through space would be
fine.  Moving platforms you can jump between in a game is an example where
you don't need inertia badly.

Of course, I can do this myself by transforming the vertex list but I was
surprised to find that tri-list geoms didn't respond to dGeomSetPosition().
This approach also requires two vertex lists so errors don't build up!!

I've put up a brief wiki page explaining how I got the tri-collider
to compile and link, along with the problems I had (float/double
issues). Feel free to correct/expand on this.
