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)
A fundamental light reflection model that takes into account the internal structure of cloth to render the peculiar gloss of cloth objects is presented. In developing this model, the microscopic structure of textiles was considered. The model represents fabric features such as fiber's cross-sectional shape or weave. By measuring the reflected light… (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)
