Procedural animation of waving cartoon hair by emulating animator's techniques

This paper describes a method for creating cel-style CG animations of waving hair. In this method, gatherings of air are considered as virtual circles moving at a constant velocity, and hair bundles are modeled as elastic bodies. Deformation of the hair bundles is then calculated by simulating collision events between the virtual circles and the hair bundles. Since the method is based on the animator's technique used in creation of the traditional cel animations, it is expected to suppress a feeling of strangeness that is often introduced by the conventional procedural animation techniques.
