Modeling and rendering of individual feathers

Abstract

We present a model for geometric modeling and rendering of individual feathers for computer graphics purposes. The model represents feather structure with a collection of parameterized Bezier curves. This parametrization allows easy generation of the existent types of feather structures with biologically-motivated parameters. Once the feather structure is defined, feathers can be rendered either in a non-photorealistic rendering style or using texture mapping to achieve a more natural look.
