Far as I can tell, ODE is used only to generate contacts after Opcode
itself determines whether there's an overlap within the bounds of the
triangle.  Collision detection and contact generation are related but
distinct problems; Opcode does the former, and the tri-collider glue uses
existing ODE code for the latter.

At least, that's the impression I got from looking at the source.  Pierre
and/or Erwin can probably answer this better than I can, it's their code. :-)
