Should be able to do it by subclassing Canvas3D and overriding the
postSwap() method:
public class myCanvas extends Canvas3D
{
public Object waitObject = new Object();
public void postSwap()
{
waitObject.notifyAll();
}
}
Then instead of Thread.yield() etc. just call myCanvas.waitObject.wait();
Hope it helps,
Ewan
