SSAO in Fugu

I implemented a new visualisation into fugu today – Screen Space Ambient Occlusion. It is a shader effect (implemented fromĀ this discussion) that darkens creases and nooks of the model, as well as making individual parts stand out more. Below is a fugu model renderered as (top) flat-shaded, (middle) flat-shaded with SSAO, and (bottom) Phong shaded and subdivided with SSAO applied. I hope to get it stable and operational in the main fugu release soon. :)
