Hi, I'm trying to create a rocky surface of bauxite and I was wondering what
would be the easiest way of doing it. Should I use a bump map of noise
generated from photoshop? I don't think it will give an visual of pebbles,
but more of tiny spikes or mountains instead.

The surface should similar to what is shown here:

Obviously I don't want to go in and render each pebble individually, but is
there something that can generate a field of them automatically or give the
appearance of them?

I'm a relatively new user of povray and 3D rendering programs in general, so
any help would be appreciated.
