geometry. For the viewingPlattform everything see

Hi,
I have some problems with geometry compression. During decompression the

java.lang.ArrayIndexOutOfBoundsException appears.
Most of the objects are compressed/decompressed properly but in some cases
the decompression fails.
Any suggestions ?

I also made a 3DS loader that reads the animation, but be aware that 3DS

If two Locale's are close to each other, it is possible for one Locale
to see the geometry in the other Locale. The only way to ensure that
geometry is completely seperated is to use multiple VirtualUniverse's.
There may be a Java 3D bug here, but I just wanted to clarify that point.

Java 3D has it's own native rendering layer which is at a much
higher level than OpenGL or DirectX. Going across JNI is a
very expensive operation, so we try to make sure we have a lot
of work to do when we do go through JNI. Also, by having our
own native rendering layer, we can abstract it abo
