Hi,
Try GraphicsConfigTemplate3D
public void setDepthSize(int value)
instead of using the default return from SimpleUniverse.
See 4760874 - Java3D 1.3 OpenGL version on Matrox 450 no supported
Graphics Configurations
I submitted the related bug 4760874, and finally got a chance to submit
The outputs looks right. Please rotate the scenegraph such that
the ball and the cylinder overlay from you point of view. Then
you will see one them looks transparent!
Sorry for any confusing in the previous explanation.
Thanks

How does the Shape3D handle a list with multiple geometries (of the same equivalent
class of course)? I assumed that each of the Geometry objects would be displayed.
However, I tried adding two TriangleStrips to a Shape3D object and it seems to be

Hi Florin,
Thanks for explanation. I tried what you said for quite a while.
The problem still exists. I checked the transformations, finding nothing
unreasonable.
I think this is an interesting problem. So, I wrapped around the code
