Title:

    Display of Diamond Dispersion Using Wavelength-division Rendering and Integral Photography

Presenter(s)/Author(s):



Abstract:


    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 dispersion ratio. However, diamonds are difficult to express by conventional 3DCG because of the two following reasons. First, common 3DCG applications usually do not have dispersion rendering function based on physical laws. Second, a single 3DCG image does not have information of views seen from different camera positions. To overcome these difficulties, we propose a new method in which dispersion rendering and integral photography (IP) are integrated.
