Real 3D (IMAX like) get pixelinformation from view

Hi, I made some experiments creating real 3D pictures, watchable with red/cyan glasses, with the A7. And more ore less I succeeded. The problem is once again the framerate. For creating a stereoscopic so called anaglyphic image I use pictures from two differnt views with a small offset between them. From each pixel of the views I take the colour information and calculate the colour of the pixel in the 3D view. Creating the picture pixel by pixel with "pixel_to_bmap" is not fast but this is not the problem. The problem is bring the two views in a format I can read from with "pixel_for_bmap" and "pixel_to_vec". First I displayd them on screen made a screenshot and read from this. This was really dumb and very slow. Now I render them both to one texture an read from this. The Problem is I have to do "bmap_to_format" first. And this is so slow I get only 2fps creating a 400x300 3D image. Converting the 800x300 texture containing the two views takes most of the time. Is there a faster way to get the colour of pixels in a view?

Here a 3D picture created with the A7 if someone is interested to try itself. Use glasses with a red colour filter in front of the left eye and a cyan colour filter in front of the right one to watch it.

maybe you should use a postprocessing shader for this. i dont have sucha 3d-glass otherwise i'd already have tried it

I thought about a postprocessing shader, too. Unfortunately I'm not familiar with shader programming.

So if someone is interested in accepting this challenge please contact me. I for myself do this experiments not for one of my own Projects. Just to ceck what is possible with the A7 and provide this knowledge to the community. I'd glad if someone wants to join my research.

I made my glasses myself. All you need are two colour filter gels which cost about $1 each.

aint that problematic because you need somewhat normed colors to get it working? or else i could think of creating a panel where you can adjust the colors for the stereo image.
