Get ready for another co-processor: further details on Caustic Graphics's RTPU
Ray tracing is the current holy grail of gaming graphics, the rendering technique that might finally make the licensed game based on Pixar's latest look as good as the film itself. But, the typically random nature of rays has made rendering them on traditional hardware inefficient, a problem Caustic Graphics claimed to have solved, and is now backing that up by giving PC Perspective some further details and demos. The company's tech will rely on a new graphics co-processor called the Ray Tracing Processing Unit (RTPU), working in concert with existing 3-D accelerators to deliver rays at frame rates high enough for interactive applications. How high? Early hardware dubbed CausticOne (that giant slab of silicon above) manages 3 - 5 frames-per-second in the demonstration video after the break. That's not nearly enough for twitchy first-person shooters, but second-gen hardware due next year is looking to deliver 14 times that -- plenty to get your high-reflectivity frag on.
Caustic Graphics develops ray tracing at gaming speeds
The ray-tracing technique for generating 3D images is an extremely processor-intensive proposition that doesn't lend itself to gaming (or real-time anything, for that matter), but all of that may be about to change. Caustic Graphics, a San Francisco-based start-up founded by former Apple employee James McCombe, claims that its dedicated ray tracing card will produce photorealistic graphics at a rate 20 times faster than products currently available. And if that weren't enough, their new CausticRT platform has the potential to perform the operations a whopping 200 times faster -- possibly fast enough for a photorealistic gaming platform. The second generation technology should be unleashed sometime in mid-2010, while the CausticOne card will get its official announcement on April 23 of this year.[Via Business 2.0 Press]
