Paul was kind enough to meet with me a few times, probably over a decade ago now, when I was a lost student trying to work out what ideas were worth exploring (I guess I still am). He showed me some photogramatery work he was working on, I was amazed at how smooth everything was running given the precision and having worked with highly detailed tins and pointclouds myself on that days high end hardware. I asked him what kernel/engine he was using. He casually said it was his own. Which (having done toy ray tracing in C and dabling in openGL) blew my mind but also made me realise it would be absolutely necessary in order to do this kind of work with the type of control he needed. Everything from the ground up. One of the few academics/researchers I've met who is 100% legit.
