A method to generate wet and broken-up animal fur

This paper describes part of the pipeline which we have implemented for the creation of hair and fur for the upcoming motion picture "Stuart Little". In particular, we discuss the two effects of producing wet fur and broken-up dry fur. We assume that our animal models consist of a connected set of NURBS patches, which define the skin onto which the individual hairs are placed. A wet fur look is achieved by clumping together of neighboring hairs within certain clumping areas on the skin. The definition of these clumping areas can be either static or animated, the latter to simulate spouts of water hitting parts of the fur coat, making it increasingly wet. A broken-up fur look is generated by breaking of hairs along certain fur-tracks on the skin.
