Show HN: Procedural 3-D worlds for autonomous systems ML

Some fun facts:

- the raw video is 58 seconds

- at 24 frames per second, that’s 1,392 frames

- on a single, high-end GPU, it takes 168 minutes to render a single frame (we render on 8-GPU systems)

- that’s a total of about 3,900 hours of render/compute time
