Toon Shader

A shader that makes the object cellshaded and gives it an outline.

How it works.

Cellshading:

The cellshading works by turning the lightvalue to a texture coordinate (0 to 1), then it multiplies the color of that texture coordinate to the object texture to get the final color.

Outline:

It gives the object an outline by rendering multiple streched objects, only showing the backfaces and coloring them a predefined color. The amound it's getting streched is also determined by a predefined number.
