High!

While my machine closes in on the last few hundred frames of a 
3600-frame animation of an isosurface desert world, I started to ask 
myself how to achieve a more realistic surface relief. From high 
altitudes, my simple granite pattern mountains look fairly believable, 
but when rendering a scene from "pedestrian perspective" (as attached 
below), they look like soft undulating sand dunes rather than rugged 
mountains - and the outlines of land forms are very crude!

I would like to add some "ruggedness" while also keeping the lower 
altitudes smooth - how can it be done? Is it possible to use a 
texture_map also with isosurfaces?

See you in Khyberspace!
