Asteroid Field

I'm back to working on asteroids tonight.  Here's a simple field of them.  Unfortunately, you can't see the detail so well, since I had to turn down the quality to allow generation of a whole field in a reasonable amount of time.

I'm now using value noise as a basis for the coarse shape of the roids, then traditional Worley noise for the finer details.  There's also a cratering pre-pass, but the craters aren't very visible in this shot.
