I've seen several uses of 3D in Pico-8 games and I'm wondering if anyone knows of any good tutorials to better understand the process of setting up a 3D area? I've looked at the code of some of the games that setup 3D, but they're not clearly documented or I'm just not grasping it.

I'm new to Pico-8, but I've watched several good videos about basic 2D development. I have something I want to try, but I just need a better grip on how to set it up.
