What is Illustrate!?
Illustrate! is a non-photorealistic renderer.
It allows you to render your 3D scene in a variety of artistic styles. The most common is the cel or toon style where the objects are rendered with a single or limited number of colors and the edges are drawn with a line. This version of Illustrate! is particularly adept at this style of rendering. It includes a lot of advanced features for creating film resolution cel renderings
