(Left) Photo captured through the window of a train using a common handheld device and viewed through the polarising lens of a pair of sunglasses. The window exhibits stress-induced birefringence which gives rise to the visible iridescence. Notice that the visual effect is most powerful when the incident light is reflected off the road as light reflected around the Brewster’s angle is strongly polarized. (Right) An optically anisotropic slab rendered using our method and exhibiting iridescence induced by birefringence as well. Incident light was assumed to be partially polarized.
