Abstract

For the correct optical presentation of metallic luster structural color, reproducing the changes in brilliance and color that accompany the movement of the viewpoint is essential. Light-field projection onto a retroreflective surface can optically present a texture depending on the viewpoint. Through this application, the apparent shape can potentially be manipulated depending on the viewpoint. This paper proposes an optical illusion that manipulates the apparent shape of a 3D object using light-field projection based on a perceptual normal map transformation.
