Why does the Java3D canvas flicker when I call Canvas3D.repaint()

问题

I have 2D elements I draw with postRender() on a Java3D canvas and want to animate these elements. In a loop I call Canvas3D.repaint():

while(animationIsRunning){
    // I update positions of 2D elements here...
    // ...
    canvas3D.repaint();
    Thread.sleep((long)(1.0/30.0 * 1000));
}

For every short animation, this causes the whole 3D canvas to flicker once or twice.

回答1:

I think I found a solution in my case:

Instead of

canvas3d.repaint();

I invoke

canvas3d.getView().repaint();

This way I can update my animation with high framerate without flickering.
