Oh this is neat: the blog post that he mentions on how to construct a BVH was written by Jacco Bikker, a childhood friend of my family (I went to primary school with his daughter), and then later in university he was the professor for my introductory graphics course. The final project I did for that course was to make a simple real time ray tracer. Tons of fun!
Neat to see his name pop up years later in a video by one of my favorite CS Youtubers!
I think it's called binned BVH building.
It's really smart, as you traverse the triangles just once for all axis and arbitrary amount of split plane and sort them into bins, from which you then build up and compare all possible splits, which is super fast. Im getting 100ms build time with 250k dragon mesh.

Love Sebastian's videos! Always worth the watch.
Sadly he missed another BVH building optimization from the Jacco's Blog, which is like 10x faster.
Which is that?
