[ODE] dTrimeshDataID structure

[pvaz at apportmedia.com]

Hello,

I use ODE to make a car simulation. At this time, the car collides with 
a big trimesh and it works well.
I would like to discuss an idea to manage the collisions otherwise : can 
we imagine create a local trimesh under the car that follows it for the 
colllisions ?
I don't want to allocate memory at each step, so can we modify the 
triangles data in the dTriMeshDataID structure and so just call 
dGeomTriMeshSetData (dGeomID g, dTriMeshDataID Data) to replace the 
current data ?

I don't know if it's a good idea, perhaps i'am totally wrong!

Thanks,
Phil
