Hi

You can easily do it with Ardor3D as you can see here.

Please post the whole class cast exception you get. You should have a look at existing examples here. This example shows how to use JMonkeyEngine 3 with several canvases in a JFrame.

That JME3 example works in windows, but not the RPI (no display).  THanks.  However when i try to get the GLCanvas there still runs the issue of getting the following error:
