[ODE] compiler crash / trimesh collision questions

[James W. Walker]

I tried to build ODE, but every time I tried to compile one of the 
collision_trimesh_*.cpp sources, CodeWarrior 9 crashed (on Mac OS X). 
I started with the CodeWarrior project in the contrib folder, but it 
is more than 2 years old.  Is anyone using ODE successfully with 
CodeWarrior 9?

Since I really just want to do collision detection with triangle 
meshes, I decided to try using OPCODE without ODE.  There does not 
seem to be any mailing list or forum for OPCODE, and the 
documentation is out of date, so I hope y'all won't mind a few OPCODE 
questions here.

The OPCODE release notes mention a HybridModel that sounds better 
than the regular Model, but I see that ODE uses Model.  Anyone know 
how to use HybridModel?

I tried using OPCODE in a test case, and it took something like 50 
times longer than my homegrown test.  The vast majority of the time 
was spent in Model::Build, not in AABBTreeCollider::Collide, so I 
guess the moral is that I should cache the model rather than 
computing it on the fly at each test.  But still, that work has got 
to be done sometime, and if my program has to sit there building 
models for a couple of minutes every time it loads a scene, it's not 
a good thing.  Am I missing something?
