真实感渲染的参与媒体,如云需要多个各向异性的光散射。本文提出了一种光散射到M个方向面元的传播近似,它减少了传统的“离散坐标”方法中的“射线效应”问题。对于n3个元素的规则网格体,计算时间为O(Mn3logn + M2n3),空间为O(Mn3 + M2).
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.
