Hi,
When using "picktool.setMode(picktool.GEOMETRY)" I am not able to pick
linearrays/linestriparrays. Is there an explanation to this? It works fine
when picking other objects like cubes, cylinders, and so on.
Thanks

Hi everybody,
I think I've hit a wall in writing a simple Java3D program. I am getting an error:
Exception in thread "main" java.lang.OutOfMemoryError
My question is: what is the largest possible array size I can declare in Java?

Hi Corysia,
Bug 4481521 - D3D: Raster color affect by TextureAttribute textureMode

There are known problems with our installer and the 1.4 Beta VM.
This is bug 4464766. You can keep tabs on the status of the bug

See the bug report for a workaround, or if you don't require 1.4,
use 1.3.1 for now.

Rasters are implemented in D3D using texture mapped polygons so the failure is
likely due to a limitation in the particular graphics card you are using. Do

Hi
It is possible to keep a label constantly in front of an object. A very
simple way of doing it is to take the old position vector of the label and
the current vector from the view to the center of the object.
You can turn one vector into another by normalizing the current view vector
and multi

Does anyone know if anyone has given any serious thought to using POV-Ray
as the basis for realtime 3D graphics - perhaps using a POV-Ray loader for
Java3D? I've always thought POV-Ray was a rather beautiful language -
enormously much more elegant and powerful than VRML, for instance - and it

Does anyone know how to pick Objects which are

I think it is not possible with pickClosest from a BranchGroup because
it is not using virtual world coordinates.

Well basically it doesn't matter if you transform all the objects or the
view. But performance wise it's better to transform the view if possible.

There are quite a few tutorials,

I think there is actually quite a lot of demand for *any* MPEG4 BIFS

wrong people. I don't know if you've tried any of what's available by way
of players, but from what I understand there is currently much left t
