Augmented Reality Sandbox - realtime topographic contour lin

Neat stuff. I think it would be cool to be able to model road/bridge jobs during design phase. Maybe a 3D sand printer?

Fill the box with kinetic sand.

I wonder if you could overlay two sets of contours - one of the plan, one of real time, then colorize based on cut/fill needs.

I could see how you could use this technology to use as an aid in duplicating models. In other words, use clay and keep shaping it until your physical model matches the digital model. You could use colors to show where cuts needed to be made. When you get all one color, the surface matches. Something like that.

I once made a scale model of the volcano Mt. Shasta, by tracing the contours onto a piece of plywood, then placing wires in a piece of plywood at every contour. I then covered those wires with paper mache and painted it to show the lava flows, timber line, glaciers, ect.

I had to do this as extra credit to pass freshman geography class. Lazy didn't pay off so well.
