- This directory contains a GLUT "hack" program for using SGI's
- proprietary X stereo extension (officially named
- "SGIFullScreenStereo"). The extension provides stereo support for
- mid-range and low-end SGI workstations including Indy and Indigo^2
- workstations with Indy, XL, XZ, Extreme, and IMPACT graphics options.
-
- NOTE: This example "hacks" GLUT to get at private GLUT implementation
- variables (basically __glutDisplay). Any program that does so is
- effectively unportable to other GLUT implementations. SGI's
- proprietary X stereo extension is not suitable for portable, direct
- support via GLUT's API, so these examples are being released as an
- exception to the rule.
-
- To use this example code effectively, you must have:
-
- o A low-end or mid-range SGI workstation described above.
-
- o IRIX 5.3, 6.1 (Power Indigo^2), 6.2, or higher.
-
- o A set of stereo LCD shutter goggles.
-
- o A monitor that syncs to the stereo video signal.
-

-
- Mike Blackwell contributed the original GLUT stereo example. The
- example itself is based on a demonstration program found in Appendix 1
- of "The CrystalEyes Handbook" by Lenny Lipton, 1991, StereoGraphics
