Awesome Video of the Day: Augmented Reality Sandbox with Real-Time Water Flow Simulation
Here’s a video that gives a pretty good testament to how technically advanced we have become as a society.
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.
