34. Photorealistic Hair Modeling, Animation, and Rendering
Tuesday, Half Day, 8:30 am - 12:15 pm
Room 29 A-D
Level: Intermediate

The full range of hair simulation problems and practical solutions, both novel research ideas and time-tested industrial practices. This course examines hairstyling, hair-hair interactions, and hair rendering using graphics hardware.

Prerequisites
Familiarity with the fundamentals of computer graphics, numerical linear algebra, differential equations, numerical methods, rigid-body dynamics, collision detection and response, physics-based illumination models, and fluid-dynamics is strongly recommended, but not necessary.

Topics
Overview of the hair-research field, multi-resolution editing and fluid streamlines for hairstyling, hair stiffness dynamics as rigid multibody serial chains, collision detection via OBB trees and adaptively sampled distance fields, techniques for hair-hair interaction using fluid dynamics or sparse-guide hairs, advanced hair illumination models, volumetric shadows, and hair rendering using (programmable) graphics hardware.
