Hi Vladimir:
A bug is filed for this. We'll address this issue
in the next release of D3D for Java3D v1.2.
Note that currently Java3D v1.2 beta1 only support OpenGL.
Thanks for your bug report.

>To: [EMAIL PROTECTED]
>
>I've run into serious problem. Nor that it is something new or
>unexpected, but time has come to solve it. So, i have the following
>exception thrown:
>
>> java.lang.RuntimeException: DirectDraw does not have enough memory to perform
the operation.
>> at javax.media.j3d.Canvas3D.updateTexture(Native Method)
>> at javax.media.j3d.RenderQueue.updateState(RenderQueue.java, Compiled
Code)
>> at javax.media.j3d.RenderQueue.nextOpaque(RenderQueue.java, Compiled
Code)
>> at javax.media.j3d.Renderer.run(Renderer.java:447)
>
>It is thrown when i 'reuse' Canvas3D object 4 the third time (during
>one runtime):
>
> // The fragment is run 4 several times to create Canvas3D
> if (firstTime)
> {
> scene3D = new SceneOutputArea(resLoader);
> firstTime = false;
> }
>
>The situation practically doesn't change a bit even when i assign null
>to the scene3D as soon as i don't need it and recreate it every time
>(not only 4 the first time the program run). The only difference is
>that in the first case i can see the scene a little while (~2 sec)
>before the exception is thrown. When I 'dispose' the scene3D, i detach
>branch groups. But obviously that hardly helps. Moreover, as i understand, it
>is not the matter of physical RAM, but rather VIDEO memory
>leakage. I use Java3D 1.1.3 (DX version). Video card - Rage128, 16Mb.
>
>So, can this be helped somehow? Has anyone occurred similar problems?
>Has anything changed in Java3D 1.2 version?
>
>Thanks 4 any help,
