This demo shows non-photorealistic rendering of 3D-scenes using GLSL shaders.
There are three kinds of non-photorealistic rendering in this demo: Cartoon Shading,
Pencil Shading and Ink Shading.
The cartoon shading mode uses cel shading to give the scene the look of a cartoon.
In all three modes, edges are drawn as a post-processing effect using a laplace edge
detection shader. To simulate the shaking hand of an artist, the edges and colors
are distorted with a perlin noise texture.
The shadows are generated using shadow mapping. Although this algorithm can lead to
ugly artifacts, they weren't avoided completely since they blend well with the style
of a painting. In the pencil and ink shading modes, the shadows are combined with a
hatch texture.
The demo also features bone animation and some simple AI.
As an extra, the demo supports left/right stereo-projections.
