Intel says their new open-source distributed scene graph code can increase the number of participants on the 3D Web by more than 20 times. The ray-tracing package for rendering photo-realistic images is supposed to be faster by 100 percent. Of course, that's when running the code on Intel-based systems. Both open-source projects were announced via this Intel press release.
Those interested in the distributed scene graph code, it's part of their Scalable Virtual Environments article with "working or playing online with a cast of thousands."
The ray-tracing goodness comes from the Embree - Photo-Realistic Ray Tracing Kernels article.
Nice job Intel on continuing to contribute to open-source, now let's just see what's up your sleeve for fixing the Intel GMA500 "Poulsbo" mess especially with the forthcoming Cedar Trail hardware.
