Appearance reproduction of material property by using projection image, Shoji Yamamoto
Sprache des Titels:
The reproduction of material appearance, especially specular reflection, is very important information to recognize material property and object feature. For the reality of appearances, the reproduction of specular should be raised with shininess and stereoscopic perception. However, it is difficult to display the real appearance by conventional display systems, because they have limit of radiance range and contrast. Therefore, our group in Chiba University has focused on the projection-based display which has high contrast and a lot of flexibility for the use of Digital Mock-up and/or design support system. My presentation consists of two parts. The first part represents the challenge for accurate specular reproduction with color matching and head tracking. The color matching is useful for accurate reproduction of texture, and the head tracking is effective for reproduction of gloss. The other part represents the challenge for real specular reproduction with binocular stereoscopic. We constructed 3D projection display with eye-tracking control for realistic specular reflection. This system enable to make an authenticity reproduction for increase of radiance and consistent 3D view.
