Sobol Sampling - Take 2
(For yet another update on Psychopath's Sobol sampler, as well as significantly better LK hashes, please see the next post in this series: Building a Better LK Hash.)
Shortly after I wrote my last post about Sobol sampling, I got in contact with Brent Burley, who created the hash-based Owen scrambling used in the paper Progressive Multi-Jittered Sample Sequences. He was extremely kind, and spared some time to chat with me about his Sobol sampler. He has also now published a paper about it:
Practical Hash-based Owen Scrambling, by Brent Burley
Unsurprisingly, it goes beyond what I had figured out on my own, and improves upon existing Sobol samplers in multiple ways. It's really an amazing paper, and I highly recommend giving it a read.
