Abstract: Transparent and translucent objects involve both light reflection and transmission at surfaces. This paper develops a realistic transmission model of rough surfaces using the statistical ray method, which is a physically based approach that has been developed recently. The surface is assumed locally smooth and statistical techniques can be applied to calculate light transmission through a local illumination area. We have obtained an analytical expression for single scattering. The analytical model has been compared to our Monte Carlo simulations as well as to the simulations by others, and good agreements have been achieved. The presented model has a potential for realistic rendering of transparent and translucent objects.
