I'm playing with anaglyphs- the 3d pictures you view with red/cyan glasses. Red on the left eye, cyan on the right.

The idea is that your monitor shoots out 3 different colours of light, because your eyes see light in this way. The anaglyph works by letting the left eye see only the red, and the right eye see the green and blue. The image is made by rendering the left eye image and multiplying by red (rgb(255,0,0)), and the right eye image is multiplied by cyan (rgb(0,255,255)). To combine the red and cyan images i put on on top of the other as a "screen" layer.

In practice, it seems my left eye can still see quite a bit of the green. That has been problematic in other pics i tried. Also, you need to make sure each eye can percieve edges/textures- so there should be a change/variation in the red, as well as the cyan (ie green or blue) in the picture.

On top of this, there's the question of how much to space the two pics, as well as the fov. I've not really worked it out, and am playing it by ear. I've decided it's not a really good idea to space the pics apart `correctly` by your eye-eye distance on screen, because if the screen displays the image bigger than i expect, or you zoom into the pic, the distance becomes to much, and it messes up. Instead i opt to have the distance go to zero or slightly negative for the "nearest" parts of the picture so that they appear at the screen or slightly in front.

Anyhow, it's a bit of fun. This pic could do with less darkness and more features for depth cues yada ya.

I should credit the peeps who made the stuff here: malefic, kozaburo, baron vlad harkonnen, trekkie girl, the judge. I think that's it.

This is all academic if nobody has the 3d specs- does anybody?
