Hello,
first of all, this has probably already been posted, but for those of you (like myself) who didnt know:
You can play Quake in 3D
All you need are anaglyph stereo glasses. It even doesnt matter wich one. All those work:
- red/blue
- red/cyan
- red/green
Example for red/cyan:
Use the according cvar to activate the effect.
Then you can finetune the effect to match your eyes.
These are the cvars:
Check this site for the complete overview.
(Many Thanks to Error for this Wiki page. It helped me many times.)
I made some screenshots.
If you have anaglyph glasses near your hand, watch them with it to get the feeling (I used red/cyan).
Without anaglyph stereo glasses you might hurt your eyes

These are the cvars:
r_stereo_angle is "0" ["0"] separation angle of eyes (makes the views look different directions, as an example, 90 gives a 90 degree separation where the views are 45 degrees left and 45 degrees right)
r_stereo_redblue is "0" ["0"] red/blue anaglyph stereo glasses (note: most of these glasses are actually red/cyan, try that one too)
r_stereo_redcyan is "0" ["0"] red/cyan anaglyph stereo glasses, the kind given away at drive-in movies like Creature From The Black Lagoon In 3D
r_stereo_redgreen is "0" ["0"] red/green anaglyph stereo glasses (for those who don't mind yellow)
r_stereo_separation is "4" ["4"] separation distance of eyes in the world (negative values are only useful for cross-eyed viewing)
r_stereo_sidebyside is "0" ["0"] side by side views for those who can't afford glasses but can afford eye strain (note: use a negative r_stereo_separation if you want cross-eyed viewing)
r_stereo_redblue is "0" ["0"] red/blue anaglyph stereo glasses (note: most of these glasses are actually red/cyan, try that one too)
r_stereo_redcyan is "0" ["0"] red/cyan anaglyph stereo glasses, the kind given away at drive-in movies like Creature From The Black Lagoon In 3D
