This paper introduces a shading model for light diffusion in multi-layered 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 […]

LED’s not only will save huge amounts of energy (they don’t yet but theoretically can) but can be used in much more sophisticated ways. Because different colours can be so easily mixed, they see opportunities galore:
-lights that change colour through the day to adjust to our bodies circadian rhythm-”
-brake lights that can communicate with the […]
