Hello pfEverybody,

I'd like to display different aspects of the same Database in Performer.
Call it a "Camera Simulation", where more than one View is active at a
moment.
So, my question is concerned about Performance:
A) Which possibilit is better for the implementation"
  * Use the same pfScene for all different pfChan's and pfPipeWindows
    and Switching the view by pfSwitch in a callback
  * or use different (distinct) pfScenes for the different Views?

B) How can I modify the rendering sequence, so that I could render the
main
    channel more often than my other windows?
   On calling pfFrame(), all views (chans) are rendered at once.

C) Where are the results of pfCull stored? In pfScene ?
    This is just the question about having different Aspects of the
scene,
    different Culling results may occur.

Any clues or sample code is welcome

Thanks in advance

Günter
