Results

demo

I implemented reinhard tone-mapping.

My procedural background is a really simple, 2D hilly landscape generated based on the screen position and a sin function so Wahoo can frolic in the fields.

I also implemented bloom, approximated depth of field, and oil painting artistic effect using a kuwahara filter.

For extra credit, I implemented gui functionality that allows you to select the post-process filters you want to apply.

No filters

With Bloom

Depth of Field

Oil Paint
