I tested it as well with only 30 spheres cos my computer is old and could
stand the 300 (I'm at work).
It seems to work fine with me.
I'm using JDK v1.4.0.3 and J3D v1.3.

I'll test it with this particular JDK version. However I do not think this
could be a JDK version issue. While testing the program you have to make
sure that the spheres which you add are in such a way that in the initial
view they are totally clipped. If the spheres are partially clipped then the

Hi Alessandro,
There is a bug in your cubemap example,
It should use,
genNormalMap = new TexCoordGeneration(texGenMode,
TexCoordGeneration.TEXTURE_COORDINATE_3);
instead of
genNormalMap = new TexCoordGeneration(texGenMode,
TexCoordGeneration.TEXTURE_COORDINATE_2);
for Reflection
It seems that when
com.sun.j3d.utils.geometry.NormalGenerator.generateNormal() runs out of memory,
it doesn't return and doesn't throw any exception.
Does anyone know of a workaround? I would like to trap this condition
and do something.
