RL has had me wrapped up in a bunch of things, some very good, some very bad -
but to kick back and relax, I was looking through some search results for videos
to entertain/inspire, and I came across an introductory Shadertoy video where
they make a grid of circles of random sizes.

I didn't think we had a simple and obvious way of already doing this, so I made
some disks, circles, filled squares, and hollow squares.

There are lots of other distance functions to choose from, to make other basic
shapes.

The shape size is currently controlled by f_noise3d, but I suppose just about
any function could be used to control the size.

It's also likely that other functions could be used to modulate the actual
shape, and with a bit (a lot) more work, this could generate some interesting
isosurfaces.  Certainly some nice height fields.

Might make the basis for a greeble texture, a cityscape, or any other number of
things, esp if implemented in 3D.


Just thought I'd share this little doodle.
