This demo shows how an interactive comic/cel shader can be written even in Java3D. It uses a similair technique described by Lake et al. What I'm greatly missing though are 1D-Textures in Java3D which would cut down some memory usage for this shader demo. You can use the mouse to rotate and zoom camera! Or change the lighting parameter with the textfields down below!

This demonstration only works with Java3D 1.3beta2 you can get it from SUN's Developer Connection

While waiting for the applet to load enjoy this sample images.
