Plasticine shading

Abstract

Plasticine is a core material in the production of stop-motion animation. In some situations it is valuable to use computer simulation techniques to generate objects that appear to be made of plasticine. In order to render this material accurately, we present a new shading model which is based on the true physical properties of plasticine. We show that our new model represents the material approximately 20% more accurately than other existing state of the art surface shaders. Results are shown comparing our new model to state of the art models and to an existing solution used in production.
