===Description===
Cel shading involves adding a “stepping” formula to the diffuse lighting calculation so that the intensity of the light is bunched up with similar intensities being represented by one value (1.0 – 0.8 = 1, 0.8 – 0.5 = 0.75, etc.), and also involves changing the specular lighting calculations so that the highlights appear solid with no attenuation.

Edge detection is a post-processing effect that involves adding calculations that look at the depth value of each fragment and find “drop-off” points. Depth values are examined and compared, and when a specified number of them suddenly change within a specified threshold, those fragments are considered an edge and will be coloured black.
