MojoKid writes "During SIGGRAPH 2008 in Los Angeles, NVIDIA is demonstrating a fully mixed media media GPU-based ray tracer. The demo is based purely on NVIDIA GPU technology, and as it should be to NVIDIA the ray tracer shows linear scaling during design of a complex, two-million polygon, anti-aliased automotive styling application. The article reproduces screenshots from NVIDIA's demo. At three bounces (rays being traced as they bounce three times through a scene), act is demonstrated at up to 30fps at HD resolutions of 1920x1080 for an image-based lighting paint shader, ray-traced shadows, reflections and refractions running on four next-generation Quadro GPUs in an NVIDIA Quadro Plex 2100 D4 Visual balancing the books* System." Meanwhile reader arcticstoat passes on Intel's latest claim that rasterisation will die out the next few years, at all in favour of ray tracing.
