Transparent objects, such as diamonds, show rainbow-like colors because of the dispersion of light that passes through such objects; white light is dispersed because it comprises light waves with different wavelengths. This phenomenon has been considered to reproduce realistic material in computer graphics (SUN 2000). However, the use of dedicated renderer(More)
In conventional three-dimensional computer graphic (3DCG) technologies, a rendered image is two-dimensional. No information except that seen from a single viewpoint is included in the rendered image, although 3D models are used to construct a 3D scene. Even when rendering for binocular stereopsis is performed, the viewpoints are only two. This(More)
Various colors, such as in a prism, are observed in properly cut diamond even under white light because of dispersion. Properly-cut diamond brings about scintillation when viewing angle is changed, because total reflection inside a diamond tends to occur frequently due to the large refractive index. Moreover, strong rainbow colors are seen because of high(More)
A four-plane depth-fused display (DFD) is an autostereoscopic system that can display four images at different depth positions using a single liquid crystal display and mirrors or half mirrors. This system increases the number of images in the depth direction, thereby enhancing stereoscopic effect. To date, however, the contents of proposed DFD remain(More)
The purpose of our project is to develop digital tools that will help to simplify the task of creature design in large-scale media projects. When working on an animation or game that requires hundreds of unique creature designs, many artists find it challenging to maintain consistency and quality in every new design. As a result, even the most creative(More)
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(More)
