Hello,
   My name's Melanie Roy (I'm French) and I working for Anne Parent at NRC.
I'm summer student and I must develop a user interface for vary parameters of
virtual environment (With Performer).

   This parameters are: Ground Fog, Frame Control, Level of Details, Texture,
Transparency, Shadows, Collide Mode, Contrast, Luminance.

   I need informations of this parameters on Performer.

   I have the IRIS Performer Programmer's Guide and a demo Perfly but I don't
have all of I need.

Questions:
      
-How I can vary Level of Details of a object? (number of polygon??)
       
-How I can vary Transparency? (Ex: Vary between opaque to completely
                    transparent with PFTR_FAST)

-How I can vary Shadows?

-How I can vary Contrast?

-How I can vary Luminance?

   If you can answer to my questions, you enjoy me, else do you know who can
help me?

   Thank you very much of your attention.
