GoochShaderDemo is an OpenGL implementation of a toonshader.
It shades surfaces with a given colordepth and draws a black outline.
For the beautiful toonlike shading effect we used an algorithm described in this book.
Extract the contents of the zipfile to your place of choice and doubleclick the exe file. The Demo runs for itself and has no user interaction.
Though some useless keys do the following:
[F1] displays about-box.
[c] switches camera to free look (arrow keys move camera)
[p] displays the path of the spaceship
[Esc] quits the demo
[+] increases playback speed
