Abstract

Manipulating the appearances of real-world objects by using active illumination is useful for XR. In this paper, we propose a method for manipulating the gloss of real objects observed by our naked eyes under omnidirectional lighting environments. Our proposed method makes use of the fact that specular reflection components are sensitive to the polarization state of the incident light and the high-frequency components of the illumination environment, while diffuse reflection components are insensitive to them. Specifically, our method optimizes the polarization angles and intensities of incident lighting environments for manipulating the gloss of real objects. We build a lighting system by using a dome screen and two pairs of a projector and a transmissive LC panel for controlling both the polarization angles and high-frequency components of incident lighting environments. We conduct a number of experiments, and show that our method achieves the gloss manipulation without using the geometric and photometric properties of an object of interest.
