In case it helps, I posted a very high-level overview in [[Announcement] MakeCode Arcade Mini Game Jam #4 - Outer Space Jam - #71 by kwx](https://forum.makecode.com/t/announcement-makecode-arcade-mini-game-jam-4-outer-space-jam/15689/71) . The projection is pretty much the usual perspective divide apart from using fixed-point math, see the `perspectiveTransform(vert: number[])` method in the _triangle.ts_ file. Before doing that, it uses [reentrant polygon clipping](https://en.wikipedia.org/wiki/Sutherland%E2%80%93Hodgman_algorithm) to ensure that it doesn’t get divide-by-zero errors or problems with behind-the-user surfaces becoming visible.
