Abstract
The course is aimed at an intermediate level and addresses the special-effects developers and technical directors who are looking for innovation as well as proven methodologies in hair simulation. The audience will get a good grasp of the state of the art in hair simulation and will have plenty of working solutions that they can readily implement in their production pipelines. The course will also be a boot-camp for aspiring computer graphics researchers interested in physically based modeling in computer graphics. The course will cover all the three main tasks in hair simulation: hairstyling, hair animation and hair rendering. First, an overview of various proposed models in the past and present, together with their strengths and weaknesses, will be presented. Subsequently, the latest methodologies pertaining to each of the tasks will be covered.
For hair dynamics, we will cover an elaborate as well as viable stiffness dynamics model of an individual hair strand. We will present novel models for complex hair-hair, hair-body and hair-air interactions.
For rendering, we cover issues related to shading models, multiple scattering, and volumetric shadows. We also discuss the recent advances in programmable graphics hardware in the context of hair rendering. Advanced issues production hair rendering, self shadowing and lighting models for short and long hair will also be presented.
