Shawn,
Can you send us a test case ?

> More Particle System fun!
> I was hoping to release this code for testing, but I have run into a
> Java3D snag.
>
> I have a Shape3D, in which, my code is manipulating it's
> TriangleStripArray.
> The problem is that as soon as the (0,0,0) of the Shape3D is NOT in
> view, the Shape3D gets culling.
> Well, that would seem ok, but part of the Shape3D, namely many many
> "particles" (which are TrianlgeStrips) immediately disappear from view.
> Well, this all makes sense to me, because when I make the Shape3D, it's
> empty, and therefore the Bounds are zero.
> However, after I load it up with geometry the Bounds need to be
> updated. Now I would prefer to do this directly because only my
> PartcileManager class would know the correct Bounds for the system. So,
> I tried:
>
> shape.setBoundsAutoCompute(false);
> shape.setBounds( new BoundingBox(new Point3d(-10000,-10000,10000),new
> Point3d(10000,10000,10000)));
>
> which should turn off AutoCompute and use my BoundingBox. In my test
> case above I just made it huge to make sure the particle system would be
> seen. But it doesn't work. The Shape3D is still getting culled when the
> origin is not in view.
>
> So the question is, what is the corret way to set the culling Bounds of
> a Shape3D?
> Thanks.
