Mapping - Spatially Augmented Reality Toolkit by Brett Jones and Rajinder Sodhi

Hát ez nem semmi: egy program, amely beméri a vetítendő felületet és autómatikusan rááll.

" We are in the process of developing a toolkit for the development of projection mapping/spatially augmented reality applications. Our focus is on projection mapping for theater and new media installation pieces using tracking with embedded light sensors.
In this demo we are calibrating a digital model of the box to the physical box using embedded light sensors. Essentially, the projector displays a pattern which photosensors embedded into the box recieve and decode. With this information, we can determine the positions of the sensors in the projectors frame of reference. With enough sensors (at least six) we can determine the parameters of the projector (the lens etc.) along with the rotation and orientation of the box. Then using a game engine, we render a 3D model of the box from the projectors frame of reference. Finally, applying an animated texture to the 3D model of the box, yeilds the demonstration above. This technique is explained extensively by Johnny Chung Lee. "
