What it is

A demo of a raycasting 3D engine built entirely from in-game mechanisms in vanilla Factorio 0.17. It renders simple 3D scenes, producing a new frame every 45 game ticks, with the video sped up to compensate for low UPS.

Why Hacker News recommends it

HN points to it as a showpiece of what Factorio's circuit network can compute, alongside other absurd in-game computing feats.
