Cartoon Style Rendering

The objective of Cartoon Style Rendering is to produce a cartoon looking rendering out of a 3D scene. Instead of rendering photorealistic images the focus lies on artistic and stylistic characteristics. In this paper we give an overview of the common methods to generate cartoon looking scenes. We describe the basic techniques for the silhouette edge detection and the shading of the interior. Then we show how to enhance these techniques to mimic various cartoon styles and methods for special effects. We present methods for silhouette edge detection that operate in image-space as well as in object-space. For the interior shading we describe cel-shading, selfshadowing, diffuse-lighting and specular highlights. Then several approaches for enhanced cartoon style rendering follow, namely Chinese Painting, Pencil Drawings, and different styles of comic artists. Afterwards we show some possibilities for special effects in cartoon style renderings, including simulation of liquids and smoke as well as methods for stylistic shadows.
