This paper introduces a shading model for light diffusion in multilayered translucent materials. Previous work on diffusion in translucent materials has assumed smooth semi-infinite homogeneous materials and solved for the scattering of light using a dipole diffusion approximation. This approximation breaks down in the case of thin translucent slabs and multi-layered materials. We present a new efficient technique based on multiple dipoles to account for diffusion in thin slabs. We enhance thisdoi:10.1145/1073204.1073308 fatcat:3zu7j3r2hndcpld3whf7mdqt2e
