Nvidia announcements are coming thick and fast, and while most of us won't benefit from their new Network GPU Appliance, it does look like an ideal product for medium to large facilities that need to have GPU power available on-tap
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
Most of us despair when we see technology and science presented to a non-technical audience on TV. It's not easy to explain stuff in the short time available, but often it's over-simplified to the point of being nonsensical. So how does a national UK broadcaster deal with the topic of 4K?
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.
It's hard to believe it, but this demo is running on a mobile chipset, in real time
It has come as a massive surprise to users of RED cameras as it has always been a much requested feature, but the official line has always been that GPU cards were just not very good at handling the debayering and wavelet technology that is involved in working with RED footage. Well this has all suddenly changed, with a new version of REDCINE-X that supports graphics card technology to take the load off the computers CPU
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
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.
