A topographic map, three hours in Three.js

Zsolt Kacso likes topographic maps and wanted one in Three.js. Three hours in Claude Code, with Fable. The time box matters because this kind of art can eat a week of fiddling with line weight, and a week would have been a different story.

A topo map fails in a specific way: the lines have to describe a surface you believe. Even spacing on a flat plane is a diagram of nothing. Bunched lines are a cliff only if the light agrees. The piece is working when you want to trace a ridge with your eye.

Three hours is also a claim about the tools. Claude Code and Fable got him to a finished art object before the affection for the reference wore off.
