Nvidia GPUs Accelerate Ray Tracing

“What used to be an excuse for a coffee break is now a real-time experience when running on Nvidia’s newest GPUs,” says Jeff Brown, general manager of the Professional Solutions Group at Nvidia. “The speed up is truly transformative for our customers – giving them interactive insight and dramatically enhancing their creative process in ways that have not been possible on individual workstations before.”

The massively parallel processing power of Nvidia GPUs is a natural fit for the inherently parallel nature of ray tracing, with the Nvidia CUDA architecture enabling software developers to develop high-performance solutions in their choice of compute languages. Nvidia also provides the Nvidia OptiX ray tracing engine for accelerating custom solutions, and iray from mental images for a complete renderer.

Companies demonstrating ray tracing solutions running on Nvidia GPUs at SIGGRAPH include:
- mental images, showing iray interactive rendering, using CUDA C, at the Nvidia booth (#717)
- Nvidia, showing OptiX interactive examples, using CUDA C, at the Nvidia booth
- Bunkspeed, showing SHOT with interactive iray, at the Nvidia booth
- Lightworks, showing Artisan, using CUDA C and OptiX, at the Lightworks booth (#225)
- Works Zebra, showing Zeany, using CUDA C and OptiX, at the Nvidia booth
- cebas Visual Technology Inc., showing Final Render, using CUDA C, at the cebas booth (#314)
- Refractive Software, showing the Octane Renderer, using CUDA C, at the Cubix Corp. booth (#1126)
- Chaos Software Ltd., showing V-Ray GPU, using OpenCL, at the Chaos booth (#313)

At SIGGRAPH 2010, Nvidia is presenting two technical papers: “OptiX: A General Purpose Ray Tracing Engine,” and “PantaRay: Directional Occlusion for Fast Cinematic Lighting of Massive Scenes.” Nvidia is also sponsoring a developer session, “Rapid GPU Ray Tracing Development with Nvidia OptiX.” Nvidia encourages attendees to attend any or all of these, where they can learn how to use GPU-based ray tracing.
