Happy Birthday Phong Shading

This month kind of marks the birthday of two very influential techniques in computer graphics: Phong Shading and the Phong Lighting Model. Both were published in the paper “Illumination for Computer Generated Pictures” 40 years ago in the Communications of the ACM in June 1975. While Bui Tuong Phong published his works also in his PhD […]

First impression of the Cyberith Virtualizer (Omnidirectional Treadmill)

I recently had a second chance of testing the Cyberith Virtualizer after a first quick run with it at gamescom in cologne earlier this year. But this time in a more relaxed environment with much more time to try it out and chat. In case you haven’t heard of the Virtualizer yet, it’s an omnidirectional […]

After a long wait since I first had the chance to test the Oculus Rift, my own device from the original Kickstarter arrived. So here are some notes after a few hours of testing: It’s more comfortable to wear than the initial prototype. Only downside: there is a spot where my nose supports some of […]

Tilt Displays – A true 3D display

When talking about 3D displays, we normally think of flat screens that somehow fake a 3D impression. Another way to present a virtual model would be to actually change the surface of your display to fit the virtual surface of the 3D model. Jason Alexander and his colleagues are just experimenting with that idea and presented […]

First impressions of the Oculus Rift

A few days ago at gamescom I had the chance to test the Oculus Rift. If you haven’t heard of it yet, check out the kickstarter project page. The Rift is basically a head mounted display build with a head tracking sensor an a high field of view screen. When you get the device for […]

OpenGL ES 3.0 – Halti has arrived

Khronos just released the specs for OpenGL ES 3.0 during Siggraph earlier today. Rumors  were going on for some time and Khronos announced that they will release something. Back in May I wrote “The best thing we can hope for is a clean rewrite of the specification text and OpenGL ES 3.0 – ideally in the same […]

The first book of this series, GPU Pro, came out 2010 and presents 41 articles on 706 pages (not counting the author introduction at […]
