Ray tracing for gaming explored

Vigile writes: "Ray tracing is still thought of as the 'holy grail' for real-time imagery but because of the intense amount of calculations required it has been plagued with long frame render times. This might soon change, at least according to an article from Daniel Pohl, a researcher at Intel. With upcoming many-core processors like Intel's Larrabee he believes that real-time ray tracing for games is much closer than originally thought thanks in large part to the efficiency it allows with spatial partitioning and reflections when compared to current rasterization techniques. Titles like Valve's Portal are analyzed to see how they could benefit from ray tracing technology and the article on PC Perspective concludes with the difficulties combing the two rendering techniques as well as a video of the technology in action."
