It has potential for the visualization of scientific simulation, material perception display, and other applications. This paper investigates how to alternate the directional illumination distribution to display a desired bidirectional reflectance distribution function (BRDF). For the display technique, we modeled the reflection property of retro-reflective coating and lightfield projection using a projector array. Because the overlap creates an illumination error with respect to the desired appearance when we simply project the desired appearance, we propose a projection image optimization method to ensure that we display the desired structural color. We performed an evaluation on the reflective rainbow of an optical disc, and its effectiveness was confirmed through simulation and hardware experiment.H.5.1 [Information Interface and Presentation]Multimedia Information SystemsArtificialaugmentedand virtual realities10.2312/egve.2015130837-44
