Evening doodle: a quick and dirty asteroid generator in #Blender.

Using cascaded noise displacement along the normal vectors, and a bit of shader magic sprinkled on top to make even low-res meshes look decent.

Blender screen capture of an asteroid generator. Different sliders control noise scale, displacement strength and the random noise position. Everything looks snappy and real-time while showing high-resolution details on the asteroid's surface.

Even asteroids need friends, so I hooked up the asteroid generator to a point cloud, tweaked a few things, and voila: asteroid fields!

The "merge" parameter doesn't really merge anything; it simply removes the randomization of the noise function per asteroid, so that nearby asteroids get similar noise values. I'm surprised how quick this still is. Granted, you need to lower the resolution, but its barely noticable from afar.

Screen capture of the Blender viewport, where I play around with different parameters for an asteroid field that, when very close together, merges into a single irregular-shaped lump of grey rock. When stretched out, the asteroids have different sizes and shapes.
