Well that contradicts just about everyone else's experience. I'd say you badly coded your application in the first place. Time to pull out the profiler and see what you are doing wrong. > a 3D mouse rotation of an object and the actual time that the rotation ends > is long enough for me to leave and go take a long crap....arghghghghghg Does it happen only when you drag the mouse, or at all times that the mouse is over the window? I've come across a very annoying bug in the combination of Swing and Java3D that exhibits this problem. Unfortunately, I can't replicate it in a small enough test application to actually submit it as a bug. To summarise, Java3D's renderer is failing to grab the lock from the swing thread and then proceeds to not update the canvas. All the behaviour loops still run at full speed, just no pixel blitting takes place. From what I can tell, this only happens on the mouse drag case. That is, each time the system issues a mouse drag event, it prevents the screen from redrawing. It is proportional to the number of drag events too. If the mouse does not move, but the button is down, there's no problems, and the faster I move the mouse, the longer the delay before it gets back to repainting the screen. The visual effect is that it locks up the rendering, but the reality is that it just skips the rendering cycle altogether. -- Justin Couch http://www.vlc.com.au/~justin/ Java Architect & Bit Twiddler http://www.yumetech.com/ Author, Java 3D FAQ Maintainer http://www.j3d.org/ ------------------------------------------------------------------- "Humanism is dead.
