so i'm having much fun with anaglyphs lately.

here's a sketch to demonstrate the technique i'm using: http://pastebin.com/kz9qerzJ
(peasyCam needed)

the camera translation in pseudocode:
Code:

cam.saveRotations
objects.renderLeftEye
cam.rotateALittle
objects.renderRightEye
cam.loadRotations
 

it works pretty nicely, the perspective is correct. But i have to lock the cam rotation so it rotates only on one axis, else the transformation is off. There is no way to look up/down.

any ideas on how to implement proper camera movement, WASD+mouse for example?

of course i could translate/rotate the models instead of the cam, but there's another issue:
the pseudo-depth of field calculations need to know the distance between cam and object. I've tried using modelX/Y/Z after translations, but it was rather confusing/did not work.
