It's hard to believe it, but this demo is running on a mobile chipset, in real time
We thought it was pretty remarkable when Nvidia announced their new Tegra 4 chipset that will bring 4K capabilities to tablets and phones. And it is. But it's no longer unique. To pretty much everyone's surprise, Qualcomm said yesterday that they too were going to release a 4K video-capable chipset too
It's really, really hard to create a GGI human face that's convincing. If you know this, then you also know the reason why so many blockbuster movies (Antz, Bug's life, Cars, WALL•E etc) have been about things and not humans
Nvidia have made a presentation from this year's Siggraph available, showing how Pixar is using its OptiX GPU accelerated lighting to speed up previewing of scenes
GPU acceleration - using a graphics card to do graphics-intensive tasks that the CPU would otherwise have to do - has transformed 3D and compositing on desktop and laptop computers. Here's a short video from Eyon that illustrates this and is a good primer for anyone unfamiliar with the concept. It also explains the difference between Nvidia's GeForce and Quadro cards.
Just in case anyone was in doubt that the 4K revolution is happening, Nvidia has just announced that its much anticipated Tegra 4 mobile chipset will include "4K Ultra-High-Def video support"
How do you choose between consumer and pro graphics cards? Low cost and high performance are compelling with the lower-end products, but compatability and support are better with the professional versions. Oren Payton explores this in depth
Ray Tracing has always produced the most spectacular results of all CGI techniques. We've all seen those images of chrome balls on chess-boards, with every reflection - even between multiple balls - faithfully rendered. And "rendered" is the important word here, because, until now, real-time ray tracing on anything other than a supercomputer has been impossible.
