[ODE] How to detect colliding parts in geometry group?

[David McClurg]

Yes.  Notice that the near callback is passed the geometry group but the geoms returned from dCollide() are the geoms _in the group_.  you have to call dCollide() before you get to know which part actually collided.  It might also speed up your simulation to put all your world geometry in a single group since they may not self collide.

Hi,

Would it be possible to detect colliding part in the geometry group?
For example we have a car which consists from 5 parts: car body and 4
wheels attached to the body. Is it possible to detect which wheel
collides with other world geometry and which one does not collide?

Thanks in advance,

 Sergei
