Natural user interface for integral photography of dispersion-rendered diamond

Published: 27 February 2016 Publication History

Abstract

The color of the diamond is dependent on the difference in the refractive indexes by wavelength, so we developed a dispersion rendering system using wavelength division [Maki et al. 2014]. Although various rainbow-like colors can be reproduced in the stone by this technique, another technology is necessary to reproduce the brilliance of a diamond, which is caused by the ray entered from outside that reflects and refracts many times on the surface. We introduced the extend fractional view (EFV) integral photography (IP)[Yanaka 2008], which is considered to be a display method of four-dimensional light field [Levoy et al. 1996, Gortler et al. 1996 ]. We developed an IP system reproducing a three-dimensional image that changes color depending on the direction an observer looks at in about 30 degrees of the primary viewing zone. [Maki et al. 2015] However, the observer cannot choose the direction of looking at a diamond beyond the viewing zone. To remove this limitation, we developed a more sophisticated system in which the viewer can look at the diamond from any direction they like, by naturally rotating it with his/her hand.
