OH! Isosurface! I should have guessed. Thanks a lot for sharing the code.
My own attemps will probably remain non-iso's cause I'm considering ways to
cover any object with snow and drifts.. And I want it to render quicker,
too.. Those big hopes won't be easy to fulfill, but it must be possible with
"trace" and a clever use of primitives / triangles as "bottom layer" for the
drifts and some blobs at the surface of them.
I've recently read articles online about the behaviour of snow in real
life.. I couldn't find much free stuff about 3d snow however.. Have you had
any luck? It would be interesting to dig into this with Pov cause there
seems to exsist very little.. I know there are some cheap looking features
in commercial modellers but that doesn't interest me.
Best wishes,
Hugo

I used to trace to place the snow in the foreground in:

but it was a rather brute force approach....

Good start, the rock texture should IMO more follow the terrain shape, it
right now looks very much painted on it.
Concerning the terrain shape, maybe try some different RMF parameters.
Those curved ridges on the hillsides are a common problem about RMF but it
should be possible to mostly avoid them by tweaking the parameters.

Yeh - I'm always having trouble with this. I was hoping I'd get away with
passing them off as snowdrifts...
