A retrospective of my tech career - a work-focused autobiography, basically - feels a bit vain, but I'm hopeful that it is interesting or useful enough to justify that.
If nothing else writing it up forced me to try to remember what actually happened.

So, I made a hair shader that doesn't require any specially made meshes or textures.
Initially I made this work by sampling many normal directions rotated around the hair strand direction, but I eventually got an approximation working that doesn't rely on multi-sampling.

For anyone who's tried to use spherical harmonics for lighting and found the notation- and terminology- heavy definitions confusing, highly recommend this classic: grahamhazel.com/blog/2017/12...
I think Graham Hazel's blog was down for a long time, years maybe, but works now!

TinyBVH 1.6.6 is out on main. Changes:
* Improved speed of FullSweep (thanks Julian)
* Reverted JobSystem to basic threading because of instabilities
* Wave_tracer now uses TinyBVH!
* Fixed speedtest of GPU BVH
Because of the threading issue: Please upgrade to 1.6.6 asap.
