I just finished writing a blog post, New Ideas in Raytracing. It's about my two favorite new-ish raytracing techniques: stochastic progressive photon mapping, and divide-and-conquer raytracing. I don't do a lot of raytracing in my day job, but like lots of graphics programmers I'm an enthusiast of the subject, and I try to keep up somewhat with what's going on in that field from year to year. I thought these methods were worth sharing.
