Abstract

We present a novel approach for modeling hairusing level-of-detail representations. The set of representationsinclude individual strands, hair clusters, and hair strips. They arerepresented using subdivision curves or surfaces, and have thesame underlying base skeleton to maintain consistent high-levelphysical behavior when a transition between different levels-of-detailoccurs. This framework supports automatic simplification ofdynamic simulation, collision detection, and graphical renderingof animated hair. It also offers flexibility to balance between theoverall performance and visual quality, and can be used to modeland render different hairstyles. We have used these level-of-detailrepresentations to animate various hairstyles and obtained noticeableperformance improvement, with little loss in visual quality.
