[ODE] Collisiondetection with triangles

i could use the trimesh geom, but i thought it would be too much overhead.
I need it for our 3d mapeditor for surface modelling - writing CD on my own
isnt really useful, because ODE is now very nice integrated into our
software. So I'll use Trimesh

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).
