Maybe it is a newly terraformed planet, and the water cycle hasn't
existed long enough to weather the rocks very much. :-)

That is nice.

Intriguing. Never used those multifractals. Any chance to have a peek at the
source?

I'm not sure I understand this?

I'm not sure I understand this...trace() is not scale dependant. It
takes a starting point, an object, and a direction, and intersects the
ray defined by the start point and direction with the object. The size
of the surface or distance of the intersection don't matter.

Hmm, you could probably do a nearly infinite flying animation by moving
the containing box for the landscape along with the camera, and using
the noise3d() function instead of rand() to place the rocks and trees.
Or you could just make a really big landscape...
