"Ringing" on objects in CAVE system

To troubleshoot this, do you have the ability to view the same or similar gradient in active stereo independently of Vizard? The fact that you don’t see it without the glasses suggests that it’s a timing issue between the glasses sync and the DLP light engine. I think it’s worth a few tests to see if you replicate the artifact in other tools. Besides using a different 3D renderer for the same scene, you could try a simple 3D stereo picture viewer such as what nVidia provides with their “3D Vision Driver” (see this page for details: http://www.nvidia.com/object/3d-vision-photos.html). For the stereo picture test, I’d suggest just loading the identical smooth gradient in both left and right eyes, engaging active stereo, and viewing with the glasses to see if that also causes the artifact. My prediction is it will.
