Viewing Red/Cyan Anaglyphs with the Rift
Howdy, I'm trying to experiment with viewing red/cyan anaglyph photos and videos using the Rift. I tried rendering a transparent cyan layer over the right eye and a red over the left, but it didn't...

The way you do it is you discard a particular color channel (or pair of channels) from each eye.
So for standard red/cyan anaglyph you would discard the red channel from the left eye, and then discard the blue and green channels from the right eye. You can do this pretty easily with a full-screen pixel shader, for example.
You don't discard any colors because that will break the image.
What if there was a blue object.
In one eye you would see the blue object, and in the other eye you would not even see it.
You would instead combine (R+G+B)/3 per pixel, and put that result into either the red, or blue channel for left or right.
