Abstract

This course is a resource for applying efficient, real-time shadow algorithms. It builds on a solid foundation (previous courses at SIGGRAPH Asia 2009 and Eurographics 2010, including comprehensive course notes) and the 2011 book Real-Time Shadows (AK Peters) written by four of the presenters. The book is a compendium of many topics in the realm of shadow computation. The course provides an overview of various techniques but moves beyond the basics to practical solutions and game-relevant techniques summarized by a presenter from the production industry. Topics include: the theory behind shadow computation, when physical accuracy can be replaced with plausible shadows, implementation details, and practical issues such as budget considerations and performance trade-offs. Case studies illustrate the techniques behind major game titles and upcoming engines.
