摘要：Transparent and translucent objects involve both light
reflection and transmission at surfaces. This paper
presents a physically based transmission model of
rough surface. The surface is assumed to be locally
smooth, and statistical techniques is 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
previous simulations, and good agreements have been
achieved. The presented model has potential applications
for realistic rendering of transparent and translucent
objects.
