Ok, my solution is to catch only Entry/Exit events (with USE_BOUNDS,
not USE_GEOMETRY, because the former is much more precise). Set bounds
to the size bigger a little bit that your model. Use the model as an
arm object. The objects in the scene - as triggers. Surround both the
arm object and the triggers by bounds (either spheres or boxes). Don't
forget to setCollidable(false) on any other object in the scene u
don't want to catch the collisions with (with the ground at the very
least). Between Entry and Exit events define programmatically (not via
Java3D) in what direction the avatar can move. Everything should work
relatively nicely. And, yes, DO read some tutorial.
