I published the first version of wgrepp (I didn't have a better idea for the name), currently it only has a simple SSAO effect. To integrate it, rend3 would need to create a normal buffer. Alternatively, wgrepp could also reconstruct normals from the depth buffer, but that might not be a good idea, because other effects need normals too.

[cwfitzgerald]

Great! I'll take a look at integrating this after this current milestone is over.

Looking around in the rend3 code for a good place to add the post process abstraction layer to start coding the bloom from there. You got any thoughts on where to do that and what filestructure would be prefered? @cwfitzgerald
