Getting Dirty Virtually and Literally with Kinect

From the space brains at UC Davis W.M. Keck Center for Active Visualization in the Earth Sciences

“This video of a sandbox equipped with a Kinect 3D camera and a projector to project a real-time colored topographic map with contour lines onto the sand surface. The sandbox lets virtual water flow over the surface using a GPU-based simulation of the Saint-Venant set of shallow water equations.

We built this for an NSF-funded project on informal science education. These AR sandboxes will be set up as hands-on exhibits in science museums, such as the UC Davis Tahoe Environmental Research Center (TERC) or Lawrence Hall of Science.

The sandbox is based on the original idea shown in this video: http://www.youtube.com/watch?v=8p7YVqyudiE

The water flow simulation is based on the work of Kurganov and Petrova, “a second-order well-balanced positivity preserving central-upwind scheme for the Saint-Venant system.”
