GLUT stereo demos with sync signal support

Hello all–

I’ve posted updates of my GLUT stereo demos with additional support for visual stereo sync signalling used by StereoGraphics (blue-line code) and H3D (color bar codes).

This was done as interim solution since the Mac OS X GLUT version leaves such signalling to the app. Ultimately this should be incorporated into a lower level library, driver, or other middleware, which I did for SciTech DDStereo and GLDirect.

If there are any stereo enthusiasts out there, let me know what you think.
