NVIDIA: GeForce-Powered 3D Augmented Reality Projection Mapping Sandbox demo

“Powered by GeForce GTX 750 Ti and OpenGL, the Augmented Reality Sandbox lets users sculpt mountains, canyons and rivers, then fill them with water or even create erupting volcanoes. The UCLA device was built by Glen Glesener and others at the Modeling and Educational Demonstrations Laboratory in the Department of Earth, Planetary, and Space Sciences, using off-the-shelf parts and regular playground sand. Any shape made in the sandbox is detected by an Xbox Kinect sensor and processed with open source software, then projected as a color-coded contour map. Liquids flow over the surface with realistic motion.
The Augmented Reality Sandbox is mobile and can be set up in any classroom, allowing students and researchers to see their creations come to life in color and in real time. “
