Messing around with chull

As mentioned yesterday, I’m using chull() to create some stuff.

The basic scheme is:

  • Generate a large number of points somehow
  • Repeat until done:
    • Take a small subset of the points
    • Draw the convex hull around them.

Instead of tweaked random point fields, here’s what happens when a recognizable image is used as a point source.
