Raycasting engine in Factorio (vanilla 0.17) - Facto-RayO v1.0
arrow in my gluteus maximus

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