Interactive 3D Design Using Nintendo Wii Remote

Using the Nintendo Wii remote, we create an interactive, three-dimensional de-sign program for 3D objects. Tracking the position of the ”WiiMote ” in space can be done using LED point sources as reference points, detected by the con-troller’s infrared camera. Tilt of the controller can be determined through readings of its internal accelerometers. Using this information, commands can be given to a graphics rendering engine, such as Direct3D, in order to create, modify, and move three-dimensional objects. Combining the WiiMote sensor with gestures and button presses yields a cheap and interactive user interface supporting 3D design. We im-plement a subset of the constructive solid geometry (CSG) formalism (set union) as a combining operator to build (sub)assemblies of objects. The system can be use
