It's a really cool technique, and this particular article, LLM-written or not, is the best tutorial I've seen for it.
It's been decades at this point since I did any 3D graphics work, so I've completely lost touch with the field. I didn't feel like I was missing much until I saw the literal holy SHIT-class demo at https://superspl.at/scene/c67edb74 (which was also linked on HN a while back.) I don't care about terminal-based rendering specifically, but this page did a good job of bringing me up to speed on what a Gaussian-splat pipeline looks like and how it differs from polygon-based renderers.
Those who aren't interested can just move on to the next distraction, instead of trying to police a site they don't own.
