We are working on a Quad Buffered Stereo display. (CAVE).
2 Pipes, 4 Channels.
Graphics board: InfiniteReality2E
Rack mounted OnyxII, 8 processors
Performer 2.4
Forked APP_CULL_DRAW with DBASE process.
I have a non virtual ClipTex.
If I load the cliptex into the Scene Graph, other objects suddenly change color. We use raw GL commands to draw a red line
(pointing device) in the CAVE. THIS object has its color change. Here is the kicker.... The color change occurs weather or
NOT the clipTex object is turned on (We use the draw flag.) The ClipCenter calculation all takes place in the CULL
Callback... but this code is almost a verbatim copy of /usr/share/performer/
Now this color change is selective. It only happens when the clipTex is on Pipe #1. (part or whole) The color change only
seems to effect one Eye Buffer. (the other is the right color, the incorrect eye gets very dark, if not black)
I surrounded the ClipTex Nodes with a pfPushState/pfPopState call back pair in the Draw process.... no luck.
Anyone have any idea?
