Photo-realistic rendering requires accurate simulation of light propagation according to physics laws. The best known way to solve this problem is Monte Carlo ray tracing. We describe a state-of-the-art photo-realistic Monte Carlo rendering engine.
This is part of a series of blogs on Embree, a collection of high performance ray tracing kernels. Embree has been released open source since version 1.0.
