Depth Of Field (Composition by cwright)
This composition shows a cheap way to do Depth of Field using GLTool's ReadPixels patch to read the Depth Buffer. It's not particularly fast or correct, but it illustrates the idea. More like this

Interesting, I wonder if this wouldn't come into its own treating just one or two key objects in a compositional scene, rather than the whole scene, would that help speed up the resulting composition I wonder?
Whatever, it certainly holds plenty of possibilities for offline rendering, I guess that the fps could easily be speeded up for animations resulting from QuartzCrystal renders.
Finally! This is awesome.
Also...
For an amazing "depth fog" throw in the 5x5 chroma blur in place of the current blur :)
Used in combination with computer vision = awesome. -> http://youtu.be/fvUKfhI002s
