The same author Jamis Buck also recently came out with a book called The Ray Tracer Challenge [1]. He came to my University’s Game Dev class while I was there and he showed us all about maze algorithms and such. I thought one of the more interesting applications he brought up was over world (a.k.a. map/game world) generation using a maze algorithm. Which is awesome, because maze algorithms primarily try and create a single path between any two points which seems like a great property to have in a traversable game world. You could then choose to open up additional paths to your liking.
