The Crytek Website has a new CryENGINE 3 demonstration with the super-geeky title: "Cascaded Light Propagation Volumes for Real Time Indirect Illumination." This consists of a paper in Adobe Acrobat format, a PowerPoint presentation, and a movie, described like this: "This I3D 2010 paper is a result of collaborative research with Carsten Dachsbacher. The LPV technique was extended to support secondary occlusion and multiple bounces. The propagation scheme is improved and compared to similar Discrete Ordinate Methods. Also this paper describes many additional application and implementation details." The trailer shows off what this means to the end-user, as it demonstrates some impressive real-time lighting and shadow rendering in Crytek's next-generation engine. Thanks inCrysis.
