Dear Performers,

I am using a pfViewer to show multiple channels with the intention of
having different views of our scenegraph set in each channel. I was
unable to set the view per channel via
 view->getChannel(i)->setView(view.xyz, view.hpr); and can only set the
view for the whole viewer. I then discovered this code in
pfViewerManager.C at line 429 (in the simFrame method):

for(y=0, numChannels = viewer->getNumChannels(); y<numChannels; y++)
      viewer->getChannel(y)->setView(viewer->getView().xyz,
viewer->getView().hpr);

This seems to blatantly override any per channel view setting that might
have been done by the user, and forces all channels to one view. Short
of hacking this and using my own custom pfViewerManager does anyone have
a work around.

After hearing of the new development in pfx (Siggraph), with
manipulators etc, I am eager to get this new functionality but need to
proceed with my current version asap. By the way I am using OpenGL
Performer 2.5. Has this been changed at all in 2.5.1?
Thanks,
