I'm doing that in my application (java pool game) Take a look at it, and let me know if what I did will solve your problem, then I'll send you some piece of code.

Hi All, I am having all sorts of problems with opening a number of Canvas 3D's on a particular setup of machine. I think it is to do with the graphics card / driver (ATI Radion 7500). It could be the same on the Radion 9000 mobility (I did not have long to plat with one, but it looked the same). I have tried a load of combinations of driver and graphics library, and seem to get different behavior with each, but very few really work. I have tried to summarise it below. Has anyone else run into similar problems? Does not one else use multiple canvases, or am I doing anything stupid. I would really appreciate any help. Definitions below, results here One window, multiple canvases - Old Driver, Open GL, Works fine with test case, but does not display a scene if it has more than about 80 rectangles. May be my codes problem. New Driver, Open GL, Hangs JVM when it displays more than about 7 or 8 canvases New Driver, Direct X, Works fine, but generates an error when it displays more than 7 or 8 canvases, once from each canvas more than 7 or 8 [1]. [1] Fail to create hardware D3D Device, switch to use reference rasterizer. - D3DERR_INVALIDCALL Old Driver, Direct X, Works with up to 6 canvases, 7 canvases crashes the JVM, then when you close the window you get a blue screen of death (KMODE_EXCEPTION_NOT_HANDLED?). I can get it to not crash windows by opening it through another java app, then I get a D3D error [2], again when it gets to about 7 - 8 canvases. [2] Fail to lock Vertex Buffer - D3DERR_DRIVERINTERNALERROR Multiple windows - Plain OGL, New Driver, gets slow with 3 window, grinds to a halt at 4 windows open Plain OGL, Old Driver, no noticable slowdown with 24 windows open Java 3D, OGL, New driver, works fine with 25 windows Java 3D, OGL, Old Driver, 8 windows OK, if you open 9 you get a BSOD when you close one Java 3D, D3D, New driver, works fine with 20 windows, but you get the error [1] Java 3D, D3D, Old driver, When you open you open the fifth window, the canvas is copletely shot. No error message, and when you close a window you get a BSOD. Java 3D Open GL and Direct X versions, both 1.3.1 Test case is the HelloUniverse demo added a number of times to one frame Plain Open GL, the code from http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=02 running via cygwin.
