ioquake3 now has the ability to run in anaglyph mode. i love this kind of stuff and i really wanted to try it out, so i downloaded the latest svn code, built it, renamed the binary to ioquake3-svn.i386 and copied it into my openarena folder. i then ran it from the terminal with this command-
./ioquake3-svn.i386 +set fs_game baseoa +set com_standalone 1
which compensates for the fact that there is a baseoa folder instead of the baseq3 folder that it was expecting.
then i ran a game and in the console i typed-
/r_anaglyphmode 1
to activate the anaglyph and
/r_greyscale 1
which i think makes the anaglyph work better. i'm really impressed with this. i just need to get some better colour filters that the cheap carboard glasses that i have and i'll really get the benefit. hopefully this feature will make it's way into the game engine pretty soon.
Yeah it's really sweat. I haven't tried anaglyph mode yet. The active stereo mode works too if you have quad buffer capable GPU (mostly for workstations). I just picked up an old Nvidia Quadro off of Ebay for about $20 and paired it with a Vuzix VR920 (~$330) head mounted display and am presently enjoying staring at the "life like" cracks on the floor of the arena.
Shutter glasses also kick ass if you still have a CRT and are really cheap these days.
Seriously, the glasses look stupid but everyone should try out stereoscopic Openarena or Ioquake3. This site claims to offer free anaglyph glasses if you send them a self addressed stamped envelope.
