Re: [JAVA3D] Problem in creating Canvas3D ( previously adding Canvas3D at runtime)

[Peter Kryszkiewicz]

I had a similar problem, in my JTabbedPane app, where multiple JFrames containing Simple Universes ran fine. As soon as I tried to change to VirtualUniverse and sensing the hardware configuration on one panel, everything froze.   According to the J3D tutorial (http://www.j3d.org/tutorials/raw_j3d/chapter1/world_window.html)   (------excerpt from the tutorial) --------- GraphicsConfigTemplate3D tmpl = new GraphicsConfigTemplate3D(); GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment(); GraphicsDevice device = env.getDefaultScreenDevice(); GraphicsConfiguration config = device.getBestConfiguration(tmpl); canvas = new Canvas3D(config); Then to finish, you create the canvas and it to the parent frame. canvas = new Canvas3D(config); add(canvas, BorderLayout.CENTER); Of course, a simpler way of doing this is to create a canvas with a null passed in, this achieves the same effect.   (------- end of excerpt from the tutorial) ---------     ... a canvas with null passed in does background config somehow? I used a null config and everything was fine again. Of course that still left the problem of why supplying a config to Canvas3D always created problems, but I didn't have time to chase it down yet.
