Realistic rendering of participating media like clouds requires multiple anisotropic light scattering. This paper presents a propagation approximation for light scattered into M direction bins, which reduces the “ray effect” problem in the traditional “discrete ordinates” method. For a regular grid volume of n 3 elements, it takes O(Mn 3 log n + M 2 n 3) time and 0(Mn 3 + M 2) space.
