Simplified Representations for Modeling Hair

We present a novel framework for modeling hair using simplified representations. The set of representations, including individual strands, clusters and patches, are derived from Dynamic-NURBS and have the same underlying base skeleton. Our framework supports automatic simplification of dynamic simulation, collision detection and graphical rendering of hair, and offers flexibility to balance between performance and quality. Furthermore, it is applicable to modeling different hair styles. We have used the framework to simulate different styles and obtained noticeable performance improvement in the simulation, with little loss in visual quality.
