An anonymous reader writes: Intel released the article "Quake Wars Gets Ray Traced" which details the development efforts of the research team that applied a real-time ray tracer to Enemy Territory: Quake Wars. It describes the benefits and challenges of transparency textures with this rendering technology. Further insight is given into what special effects are most costly. Examples of glass and a 3D water implementation are shown. The outlook hints into the area of freely programmable many core processors like Intel's upcoming Larrabee that might be able to handle such a workload.
