Retro Computer Rendering

Hi,
basically a rendering "engine" for those vintage CRT based rendering machines.
Hard to figure what would be "necessary"

https://youtu.be/IztxeoHhoyM for example has those beautiful trace renderings. The afterglow and step by step rendering of the objects/elements gives it some nice vibes.

Question is if and how complex this gets to draw arbitrary graphics or a focus on the rendering principle (could probably be with done with turtle in the simplest case).
