In this paper we introduce a new light reflection model for image synthesis based on experimental studies of surface gloss perception. To develop the model, we've conducted two experiments that explore relationships between physical parameters used to describe reflectance properties glossy surfaces and perceptual dimensions appearance. first experiment use multidimensional scaling techniques reveal dimensionality perception simulated painted surfaces. second magnitude estimation methods place metrics these relate changes in apparent variations properties. We results rewrite physically-based terms. The result is psychophysically-based where are perceptually meaningful, along uniform. demonstrate can facilitate describing graphics rendering applications. This work represents methodology developing models synthesis.
