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.

Real-time soft shadows in dynamic scenes using spherical harmonic exponentiation

Previous methods for soft shadows numerically integrate over many light directions at each receiver point, testing blocker visibility in each direction. We introduce a method for real-time soft shadows in dynamic scenes illuminated by large, low-...

Real-time soft shadows with cone culling
SIGGRAPH '06: ACM SIGGRAPH 2006 Sketches

We have developed a new physically-based technique for computing soft shadows from a shadow map for spherical lights. Shadow-map samples unprojected into world-space (micro-patches) are culled against a shadow cone wrapping all the possible shadow rays ...
