Hi,
  I am trying to simulate a fly through of the StarShip bridge (Star Trek!)
  by using two channels, one for the bridge itself and the other one for
  the main viewer (which will render some texture mapped sphere to simulate
  planets!).

  The problem I have right now is to convert the world coordinates of the
  main viewer (rectangle) to normalised view coordinates and use that to
  set the viewport for the 2nd channel using pfChanViewport(). Any ideas on
  the conversion process? I know the world coordinates of the main viewer.
  What do I have to do get the (changing) view coordinates?

I can (and I am) restrict the movements to keep the main viewer as a
rectangle (no rolling/pitching).

I tried pfGetChanViewMat followed by pfXformPt3 and then using the
transformation equations with no result. Somehow I am missing something...

Any pointers will be appreciated...

Thanks,
