The vertices of the icosahedron from which the input sphere was triangulated are apparent.

Presumably they're the only vertices with only 5 triangles around them rather than 6? If so, what you're seeing is the concentration of Gaussian curvature at those 12 points - for a more round-looking result you'll need to spread out the curvature by adding "dislocation pairs"...pic.twitter.com/GhKMKoaHKU

i.e. pairs of 5- and 7-coordinated vertices, as in this figure. Images from a classic paper by Bowick, Nelson, and Travesset https://arxiv.org/abs/cond-mat/9911379 … that popularized the idea of "grain boundary scars" on curved crystals.pic.twitter.com/93N12l8VKH
