Thanks! That code worked - I got something similar:

Hi,
I too get blank images using this approach but I have successfully captured

I think the problem might be that you are keeping the buffered images until
the IOThread writes them out. I seem to remember someone posting that

Have you tried to reduce the resolution of the window? This may be

I am profiling my program and found that java3d generated a great numbers

I get all blank images as well.
Java 1.4, J3D 1.3 OpenGL with NVIDIA 400MX card, Win2000.
I've also been fighting this problem using off-screen canvas.
Results are blank there as well.
I tried dropping the screen resolution to 800x600, 32bit/pixel
with no change.

Hi !
I've got 2 questions about VRML and Java3D.
First, how could you get the position of a vrml scene ?
Secondly, I want my vrml scene transparent. What is the best way ?
Any code would be very appreciated.
Thank you very much.

similar to this one though. I am getting about 10 FPS - way low for the
