The best I can suggest is to tr the OpenGL version, assuming you have an openGL
accelerated driver for your card. I found it to be much more stable than the DirectX
version (and of course the DX version doesn't work on NT4)
What I think is happening is that your video card doesn't have enough RAM and Java3D
is attempting to create primary surfaces in DirectDraw on your card to draw to.
I *think* that the following is the memory used per canvas 3D:
( width*height*4 ) bytes. (width/height in pixels, 4 because its 32-bit).
So try adding that up and see if it is more than available RAM. (If its close but less
it may still be a problem because of the way DirectDraw allocates its video surfaces).
