I have problem using the stereobuffer on an Onyx wih Infinite Reality.
I downloaded the demo programs stereo.c and stereotb.c from the
SGI web site: http://www.sgi.com/Technology/Performer/goodies.html
I used the same Makefile from /usr/share/Performer/src/pguide/libpf/C,
adding stereo and stereotb to the make targets. By default, I made
the executables using Iris GL libraries.
After using ircombine to load channel 0 with 640x480_120s.vfo, I then
ran stereo. The Stereographics CrystalEyes emitter did show a red
LED light, but I did not see any stereo images through my stereo
glasses.
The program did complain with the following messages:
----- Begin Message ---------------------------------------------------

Could the warning about "unable to determine graphics type 0" be a
problem?
I have a dual monitor system.
Running gfxinfo gives the following config:
/usr/gfx 4%gfxinfo
Graphics board 0 is "KONAS" graphics.
Managed (":0.0") 2560x1024
Display has 8 channels
4 GEs (of 4), occmask = 0x0f
4MB external BEF ram, 32bit path
1 RM6 board (of 1) 1/0/0/0
Texture Memory: 64MB/-/-/-
Small pixel depth
32K cmap, 64K external gamma
Channel 0:
Origin = (0,544)
Video Output: 640 pixels, 480 lines, 60.00Hz (640x480_120s.vfo)
Channel 2:
Origin = (1280,0)
Video Output: 1280 pixels, 1024 lines, 60.00Hz (1280x1024_60.vfo)
I also tried using 640x512_120s.vfo, but it made no difference.
Am I missing something, or should I use some other vfo file?
Any comment or suggestion would be much appreciated.
