February 18th: Post Processing Materials
This week I worked a lot on post-processing materials for Techno Towers. I got some nice edge detection working, and a cel shader set up. This was a totally new process for me and I learned an incredible amount by following several tutorials and creating custom post-process materials.

Final Shader with comic dots and edge detection.
Full Shader Nodes
I started this shader with edge detection using a kernel based on the scene depth and normal information.
This is the basics of my edge detection code, there are 4 more instances of this, each to focus on a different part of the scene.
This cel shader was the other major part of my code. It is a simple cel shader, which I used as a mask for the comic dot pattern.
The comic dot pattern was another challenge. I struggled first with getting the pattern to repeat across the screen, then I tried several methods of projecting it onto the world. I attempted planar and tri-planar projection and ended up using screen space
