NVidia Cg 2.1 Cel Toon Shading

Using standard Phong model.

Implemented using OpenGL (mac) and Nvidia Cg 2.1

All calculations are done in fragment shader.

Actual Cel Shading is done using 2 1d gradient textures for look-ups (diffuse and specular).

Outline is computed in screen-space from normal buffer (using Sobel operator).

Examples show 1) Cel shading with outline; 2) Cel shading without outline; 3) Outline
