Geometric Post-process Anti-Aliasing
Saturday, March 12, 2011 | Permalink

I have a new demo up demonstrating a post-process antialiasing technique. Antialiasing algorithms generally come with four letter acronyms, like MSAA, SSAA, CSAA, MLAA, SRAA etc., so in that tradition I think GPAA (Geometric Post-process Anti-Aliasing) would be a decent name for this one. It works by using the actual geometric information in the scene to figure out how to blend pixels with the neighbors.

Here's a comparison before and after applying GPAA:
