This is a complete cel-style renderer, allowing you to create stills and animations (sequential images) that look like cartoons. Different ink widths and colors may be specified for the internal and external edges of objects, and a fogging system is implemented. Two different styles of specular highlight are supported - a harder-edged toon style and an airbrush-like 'Phong' look. By using the bitmap background (still or animated sequence) feature, you can composite cartoon models into a photoreal environment.
toon up is supported under trueSpace 3.2 and higher, but works under 3.1 (with a couple of limitations - only the main viewport can be rendered and only "regular" output sizes (320x240, 640x480 etc) will give reliable results)
