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. 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 1

Caustic Graphics is launching an effort today to woo software developers to its new ray tracing graphics chip debuting in 2010. A rare startup in the mature graphics chip industry, the San Francisco company is creating a 3-D graphics chip that can handle ray tracing, a technique that can produce highly realistic graphics. All of the players are embracing hybrid techniques that combine ray tracing with rasterization, and Nvidia bought a ray-tracing firm last year. 2
