This is a known bug in the Blackdown Java3D implementation with those specific
types of GPUs. It still prevents me from upgrading to J3D 1.3.
So I hope that J3D1.3.1 for Linux comes -- and it comes without that bug.

Hi,
I have an app that interactively builds models of given hierarchical data
sources, it works and the models typically take about 20 - 50 MB depending
on depth and branching factor etc.
The models are rooted at a BranchGroup that I detach when I want to rebuild
the model for a new data source and

Why don't you use the texture updating tools of java3d 1.3?
You will not have to reallocate anything, and you'll be able to change your textures
as often as you like.
Moreover, you can update subparts of textures, if needed.

Yes, it might work, but then you have an extra 999 geometry objects, which
it happens to share the coordinates. Actually you have an extra of 1998
objects, 999 Geometry and 999 GeometryRetained ;)

Ah, yes. I didnt realize that the geometry leaf node could be shared
between multiple Shape3Ds inherently.
I was thinking that another possible solution, though less elegant, would
be to have 1000 Shape3Ds, each with their own geometry leaf node, but for
each geometry leaf node have it access the
Sure. You need 1000 Shape3D, and you construct each of them with a different
appearance object but the same geometry. You can't use SharedGroups because
they share also the appearance.

Hello All,
Is there currently any ways to share geometry, but NOT appearances?
For example, if I want to display 1000 spheres, but want to have all 1000
spheres share a single geometry (using SharedGroup perhaps), is there any
way to make those spheres each appear with different colors???
Thanks
