Cartoon motion blur for 3D animation

As computer-animated feature films divert from realism, the creative demands of directors and films change. A stylized or cartoon approach to motion blur in 3D animation is needed to support the exaggerated animation and visual style. Existing methods such as 3d motion blur, or 2d curved motion blur are expensive and the latitude for refining these results are limited. Three innovative particle-based techniques for stylized motion blur, developed and expanded over the course of three CG film productions, are presented here. Two are essentially point-based rendering methods, while the third includes simulated particles.
