This demo uses computer vision to track a Gizmondo’s pose relative to a reference marker. It then uses OpenGL ES for hardware-accelerated rendering of an animated virtual character that appears to be world-aligned in the real environment. The combination of highly optimized computer vision code with the speed of the nVidia GoForce 4500 chip lets the demo run with 25 frames per second on the Gizmondo gaming device. A video as well as the demo itself are available for download.
