Toe-in
“In this projection the camera has a fixed and symmetric aperture, each camera is pointed at a single focal point. Images created using the “toe-in” method will still appear stereoscopic but the vertical parallax it introduces will cause increased discomfort levels. The introduced vertical parallax increases out from the center of the projection plane and is more important as the camera aperture increases.”

Adding a single statement to the program makes it true stereo. For example, for red-cyan glasses, the magic statement is

scene.stereo = ‘redcyan’

Instead of coloring the results and additively blending them together, you should rather use glColorMask to mask only for red or cyan.
This way no need for blending which will (at least slightly) improve performance.

The asymmetric frustum code is built into the binocularity.org analgyph demo – so you should be able to use it really easily.

Good to see you having fun with 3D !

I’ll try to test asymmetric frustum parallel axis projection in a new GeeXLab demo.

However, there is one improvement that would improve the stereo effect considerably (depending on the scene).
You currently use something called “toed-in” stereo, which is not optimal.

Look for “Asymmetric frustum parallel axis projection stereo” in the following link for the correct math to do S3D:
