OptiX: a general purpose ray tracing engine. In ACM SIGGRAPH 2010 papers, Article 66 , 13 pages. The OptiXproject site includes examples which you can download and demonstrate. There is a movie of the talk for the paper here.

In Proceedings of the 2010 ACM SIGGRAPH symposium on Interactive 3D Graphics and Games (I3D '10). ACM, New York, NY, USA, 99-107. There is a nice student implementation of the algorithm here, along with notes about missing or faulty details in the paper. There is a lighter version in a report from Crytek here. Here is a 2009 talk on a simple version of the technique, along with videos (1,2).
