Hi,
When using
canvas = new
Canvas3D(GraphicsEnvironment.getLocalGraphicsEnvironment().
getDefaultScreenDevice().getDefaultConfiguration());
in some JDK/Graphics card combination you will get a frame buffer
without double buffer support.
This is because the GraphicsConfigTemplate return is not compatible
with Canvas3D if we initialze Canvas3D in the above way.
A correct way is to do the same thing that J3D does for a "null"
configuration:
GraphicsConfigTemplate3D template = new GraphicsConfigTemplate3D();
cfg = GraphicsEnvironment.getLocalGraphicsEnvironment().
getDefaultScreenDevice().getBestConfiguration(template);
This should fix the flickering without the null graphics configuration warning
message.
