The potential for real-time ray tracing has been a major talking point in 3D graphics ever since Intel announced its plans for the x86-based multi-core Larrabee discrete graphics chip at IDF in 2007. However, a new graphics company called Caustic Graphics reckons that it?s already uncovered the secret of real-time ray tracing with a chip that it says ?enables your CPU/GPU to shade with rasterisation-like efficiency.?

Caustic claims that the CausticOne ?thrives in incoherent ray tracing situations: encouraging the use of multiple secondary rays per pixel. Its level of performance is not affected by the degree of incoherence.? Explaining why traditional algorithms and parallel processing isn?t the best system for ray tracing, Caustic said that they ?ignore memory bandwidth, cache performance and parallel compute utilisation. Only primary rays get a performance benefit with this approach.?

The CausticOne is due to be released in April 2009, and Caustic claims that it will speed up the ray tracing process by an average of 20x. However, the company is making wilder claims about its second-generation Caustic product, due to be released early next year, which it says will offer ?200x the speed over today's state-of-the-art graphics products.? According to Caustic, the huge speed jump is due to the company implementing its own patent-pending ray tracing algorithms implemented in a piece of silicon.
