Is there any reason you cannot use the Trimesh Geom?
If you are just interested in the collision intersection result (no dynamics), you might be better
of doing the (ray?) intersections yourself instead of using ODE.
The four parameters of the plane are x,y,z,w (or was it w,x,y,z?) where xyz is the plane normal
vector, and w the distance (of the plane surface) from the origin (0,0,0).
