It looks very promising, Thomas! Any idea yet how you would go about
constructing an entire feature (e.g. cliffside in a landscape)?
The links you posted are quite inspiring. The first image in the first link is
something I've tried to do, but always seem to fail at. Later on that page, I
was amazed to see that sand ripples could be captured in such a way.
Ultimately, nothing will beat a full 3d simulation using voxels or similar, but
who's got the hardware for that? (Or the algorithms? ;P)
Btw, they mentioned Zion National Park. Did you ever get to go there? I was
there when I was six, on a road trip my dad took us on when following a
meandering path to Montana. Zion was my favorite out of all the places we
visited. The reddish cliffs were pure eye candy. I was hoping to see some desert
sandstone plateaus, but we never passed through any such areas :(
