This article describes how I generate an infinite city using the Wave Function Collapse algorithm in a way that is fast, deterministic, parallelizable and reliable. It's a follow-up to my 2019 article on adapting the WFC algorithm to generate an infinite world. The new approach presented in this article removes the limitations of my original implementation. I first mentioned these ideas in this Twitter thread. Objective The goal is to procedurally generate a 3D environment by placing human desig...
