[Chimera-users] DepthQ stereo projector

[Greg Couch]

Just to follow up to the list.  This is a generic problem for all OpenGL 
stereo applications due to the DepthQ projector delaying the images for a 
full frame.  So what OpenGL thinks is the left eye comes out as the right 
eye and vice-versa.

The simpliest solution that fixes all stereo applications is to use a 
NuVision stereo emittor that lets you switch the left and right eyes.
Otherwise, each stereo application needs an option to switch the eyes
and currently, chimera lacks that option (to be fixed soon).  In the mean 
time, only use the DepthQ projector with Microsoft Windows.
