Here is a great example to work with: https://www.shadertoy.com/view/XtVGD1
That's really cool. It would be nice to have a sketch technique too. I'll have to remember that one. Thanks.
A paper for the cartoon render and other techniques for doing "sketch" rendering: http://developer.amd.com/wordpress/media/2012/10/ShaderX_NPR.pdf
Create a cartoon technique which uses two shaders, a cell shader and an outline shader, to create a cartoon effect. The cell shader could initially be simple with only one Light type and basic color materials, texturing and additional Light types can be added later. The outline shader should allow the thickness of the lines to be set.
To test the new technique, setup at minimum a simple test example of the technique on one or more complex objects which the user can rotate freely.
