One of the youtubers [0] I follow uses a Delaunay triangulation pattern on points that I _think_ are doing a random walk as their intro screen. There's something very satisfying about this pattern. I'm not sure how the choice of colour for the triangles is made, but I could watch it as a screen saver all day.

- cjbgkagh 1y agoThat’s not a random walk, each vertex is moving at a constant speed
- anitil 1y agoYou're right, my read on it was that there's some randomness to the changes of direction, I'm not sure what that would be called
- WCSTombs 1y agoThere could be some randomness to the points, but I definitely wouldn't call it a "random walk," which would have very jittery paths. These points are moving along some smooth curves. I think it's probably computing a Delaunay triangulation and continuously updating it as the points move, but I didn't attempt to verify that. The colors seem to be based on a simple color gradient going from top to bottom, but it's a bit more complex than that. The color inside each triangle is not constant. Interestingly the blue channel appears to be maxed out over the whole thing (not counting the vertices), which should simplify the analysis if you want to reverse engineer it, but I'll stop there.
