[ODE] More newbie questions

[Geoff Carlton]

If you have a stand-alone "virtual object" just create a geom without a 
body - the body is the physics part, which is unnecessary if you merely 
want collision info.  However, if you want it to be attached to the body 
you can indeed do that.  Just don't create contact joints unless you 
want the ship to actually be affected by collisions with these things.

Geoms and bodies share their position and orientation.  If you want geom 
that are offset from their body use a GeomTransform.
