It seems that the GetIntersection function of the RayShape class for ODE uses dCollider between geoms, but it looks like that is only checking AABB, and not my true collision shape (a non axis-aligned box)

Can anyone explain what's going on, or how to make checking for collision work correctly?

for a simple example, a ray at the origin (blue line here) reports that it intersects with the box, even thought it clearly does not.
