I'm having a lot of troubles with this task.
I think that some very important subjects in collide re
your
scene's object.

Additional observation:
I have also added a MouseZoom,MouseRotate and MouseTranslate behavior to the
scene.
Whenever I rotate the scene(the whole universe), the object of concern
reports collision entry.(which is not yet collide and should not be
reporting so)
> What I see is:
> The object did
What I see is:
The object did not collide and the collision detection(entry) is already
triggered.
By the way, I am using vrml loader. All my objects are loaded from the vrml
file.
Do you think that is the problem?

speedhint "USE_GEOMETRY" should do the tr
Thanks. I got it working.
But I have 1 more problem.
How do I adjust the accurary of the collision detection?
I have tried using using the speedhint="USE_GEOMETRY" and hi-res coord
but both doesn't seem to improve the accurary.
Is there other thing I could try?
Thanks again.

Siau,
I'd say most of us use "picking" to do collision detection.

Is collision detection fully functional in
beta2?
Is there any other ways to implement collision
detection in J3D?
Thanks.
