Abstract
This paper is devoted to the problem of photorealistic rendering of optically active crystals. Optical activity (rotation) is turning of the polarization plane of linearly polarized light while it propagates through optically active medium. Quartz is one of well-known optically active crystals. It is an optically uniaxial crystal; however, there are optically active isotropic crystals, e.g., sodium bromate. Thus far, the phenomenon of optical activity was out of the scope of the papers devoted to photorealistic rendering of crystals. In this paper, we present a method for physically correct calculation of turning of the polarization plane of linearly polarized light in transparent optically active isotropic crystals and, for the first time, consider its application to photorealistic rendering. This method will allow extending the set of materials to construct scenes for virtual reality systems.
