Hi Robert Thanks for the reply.
My application needs cameras at different frame rates, for simulation purposes. I guess I will have to use multiple Viewers and control them manually (call frame() when needed). Is there a problem with each viewer having its own GraphicsContext? Roni --------------------- Hi Roni, The only way to do what you want is to have multiple viewers, be them CompositeViewer or Viewer. A CompositeViewer containing Viewers won't do the trick, as the nested Viewers will just be treated as standard Views, not as viewers in their own right. One thing you won't be able to do is have multiple viewers sharing the same graphics windows and have them rendering at different rates, as its the graphics window that really sets what can be rendered at what rate, this is down to the physical relationship between a graphics window, and its associated logical screen and finally the pyhsical projector/monitor. Could you explain why you need multiple views running at different frame rates. Are you sharing scene graphs between these? Are the different views sharing graphics windows? Robert.
