3D Graphics Techniques for Capturing and Inspecting Hyperspectral Appearance

Feature films and computer games exhibit stunning photo realistic computer imagery in motion. The challenges in computer graphics realism lie in acquiring physically accurate material appearance in a high spectral resolution and representing the appearance with perceptual faithfulness. While many approaches for true spectral rendering have been tried in computer graphics, they have not been extensively explored due to the lack of reliable 3D spectral data. Recently, a hyper spectral 3D acquisition system and viewing software have been introduced to the graphics community. In this paper, we review the latest acquisition and visualization techniques for hyper spectral imaging in graphics. We give an overview of the 3D imaging system for capturing hyper spectral appearance on 3D objects and the visualization software package to exploit such high-tech digital data.
