Terraforming 10 Million Grid Points Smoothly Using Burst-Compiled Parallel Jobs

I love learning about the technical aspects of game development. So, 18 months ago, I set out to learn about 2 specific topics: Tri-planar, tessellated terrain shaders and running burst-compiled jobs on parallel threads. A natural use case that combined these two topics was creating large terrains that could be manipulated smoothly in real-time, without tanking the frame rate. In this video we consider this terrain manipulation, or terraforming, and the data-oriented-design and memory management required to make it run smoothly on parallel threads. This is the story of implementing what I've learned into a gridless, interactive, world-building sandbox game called Minor Deity.
