With such a system, students can gain a deeper understanding of how land and water systems interact and see for themselves how changes to topography over time cause changes in the environment in a much more hands-on fashion than when building static models out of sand, dirt or clay.

Some use clay, but many more likely use sand, as it’s far easier and faster than most anything else. Now researchers at UC Davis have taken that model to new extremes by building a sandbox system that is capable of automatically adding augmented reality real-time coloring to the sand to indicate altitude and moving water as changes are made to the terrain with a hand or small tool.

To make the sandbox, the team combined a Kinect 3D camera, a digital projector and simulation software running on a computer and of course, an ordinary sandbox raised up on four legs for optimal viewing.The system works by first collecting images of the sandbox from above using the Kinect camera, at thirty frames per second, as a demonstrator (or student) changes the landscape below in the sandbox. Information from the camera is fed to a computer running the simulation software (Vrui VR development toolkit). The software generates different colors to represent different elevation levels in a virtual topological map. It also uses a set of Saint-Venant shallow water equations to create realistic looking water movement. Both are then projected down onto the sandbox in real time, giving the appearance of reacting to changes made by a person creating hills, valleys, rivers, streams and lakes in the sand. The result is nearly instant color coding of elevation topography and the instigation of virtual water into the modeled waterways.
