AB Transparent and translucent objects involve both lightreflection and transmission at surfaces. This paperpresents a physically based transmission model ofrough surface. The surface is assumed to be locallysmooth, and statistical techniques is applied to calculatelight transmission through a local illuminationarea. We have obtained an analytical expression forsingle scattering. The analytical model has been comparedto our Monte Carlo simulations as well as to theprevious simulations, and good agreements have beenachieved. The presented model has potential applicationsfor realistic rendering of transparent and translucentobjects.
