Detailed Description

Depth of Field Effect:

We use a gather approach by sampling a lowres version of the color buffer. The process can be summarized like this:

• down-sample the color buffer using a COC (Circle of Confusion) aware down-sample algorithm.
• do a gather pass using the COC computed in the previous pass.
• do a median filter to reduce noise amount.
• composite on top of main color buffer.

This is done after all passes and affects every surfaces.
