SUMMARY A virtual manipulation system for origami (paper folding) is described. A piece of paper defined in a computer can be deformed interactively by picking and moving a corner vertex of a paper face on a graphic screen using a mouse. Three kinds of folding operations and a curving operation transform the paper into a three-dimensional figure made of… (More)
In observing a virtual 3D object displayed stereoscopically on a large screen, there often exists a difference between the calculated depth and the perceived depth of an object. This paper presents a method for reducing such differences of depth. This is performed by modifying both the viewing position and the screen position in the stereoscopic… (More)
