Interactive Ray Tracing PS3

What is Interactive Ray Tracer for Cell Broadband Engine?

Interactive Ray Tracer for Cell Broadband Engine demonstrates the power of the Cell Broadband Engine for interactively ray tracing high-definition television (HDTV) images of complex scenes. Interactive Ray Tracer can run on both the Playstation 3 and QS20 Cell Broadband Engine-based platforms. A single Linux binary is supplied that renders the provided scene. Interactive Ray Tracer serves as an example to those interested in the digital media, graphic rendering, and high-performance computing aspects of the Cell Broadband Engine's capabilities.

Interactive Ray Tracer has been shown at three major conferences (Super Computing '06, Game Developer's Conference '07, and SIGGRAPH '07) and is now available as a downloadable demonstration for users with access to either Sony Playstation 3 or QS20 Cell Broadband Engine-based hardware. A demonstration model is provided, allowing users to animate in real time a three-dimensional, high-definition model using the tool.
