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 map.
Besides, there is no need to add
Sphere.GENERATE_TEXTURE_COORDS
flag in Sphere (optional)
After that OpenGL version works fine.
DirectX version works before probably the driver fix it
internally in hardware mode. But if you use
java -Dj3d.d3device=reference RunJ3DemoCubeMap
(assume DirectX SDK install) the result is same as OGL
version with texture coordinate mess up before the fix.
The good news is that you will not see an extra garbage line
under OGL version. We're still looking at why the line
appear under DirectX version.
Note that due to bug 4801176 -
Sphere Texture map reverse when GENERATE_NORMALS_INWARD is used
you will see texture map differently under v1.3.1 beta1 which is fixed
in the next beta2 release.
Thanks.

Hi, Kelvin.
Below is the link to a page about my experiences with
cube map texturing.
I could not run in OpenGL, but runs fine in DirectX,
but DirectX gives a strange line in the botton of the
textures (?).
But it is a amazing feature ! very impressive and not
so hard to build.
