Is it possible to use Performer with Crystal Eyes on an Indigo II
Extreme? I'm trying to set up a stereo view of an object, using a
single pipe and two channels with Extreme graphics. I've
looked through the manuals and downloaded sfly, referenced
earlier on this mail list, but nothing seems to say how I
do stereo on an Indigo II Extreme (rather than an Onyx).

I do the following:

  pfPipe *Pipe0;
  pfChannel *chan0, *chan1;
  pfCoord view, coord, viewoff;

  Pipe0 = pfGetPipe(0);
  chan0 = pfNewChan(Pipe0);
  chan1 = pfNewChan(Pipe0);

  pfSetVec3(view.xyz, 0.0f, -40.0f, 5.0f);
  pfSetVec3(view.hpr, 0.0f, 0.0f, 0.0f);
     
  pfChanView(chan0, view.xyz, view.hpr);
       
  pfSetVec3(viewoff.xyz, 0.25f, 0.0f, 0.0f);
  pfSetVec3(viewoff.hpr, 0.0f, 0.0f, 0.0f);
             
  pfChanViewOffsets(chan0, viewoff.xyz, viewoff.hpr);
  pfSetVec3(viewoff.xyz, -0.25f, 0.0f, 0.0f);
  pfChanViewOffsets(chan1, viewoff.xyz, viewoff.hpr);

  This causes the screen to go black. It appears as though
  the software is running. When I go back to a single channel,
  everthing works fine.

  Thanks,
