Perceptual Qualities of Optically Mixed Materials
Description
We present a novel setup in which real objects made of two different materials can be mixed optically in a linearly weighted manner. We conducted a psychophysical experiment in which observers rated optical mixtures of the three combinations of glossy, matte, and velvety green birds. The observers rated the materials on four scales: matte–glossy, hard–soft, cold–warm, and light-heavy. The judgments were found to be consistent and varied systematically with the weights of the contributions. This record was migrated from the OpenDepot repository service in June, 2017 before shutting down.
