[nbos] [FWE][FM8]Geology in the Fractal World
Fri Aug 3rd, 2007
I know astrosynthesis uses actual astronomical data in its generation
algorithms. I'm starting to realize part of what bothered me about
both ProFantasy's Fractal terains (other than the annoying brush shape
around the poles.) And has spilled over, to a degree into Fractal
World Explorer... The worlds are fractal and pretty... but they
eroniously imply manythings about the geology of the world... namely
they ONLY have continent on continent collision mountain building.
This gave us things such as the Appalachians (both generations of that
mountain chain.), the Himalayas, and the Urals. They don't give us
things like the Andes, the Ring of Fire circling the Pacific. They
don't cover situations like Ice Land, though occasionally you'll get
isolated islands that roughly mimic the Hawaiian chain (Or could be
similarly geologically explained) They don't give us islands chains
such as Indonesia. They seem to focus more along the islands like
Long Island, and the like, and they certainly can't cover the
complicated geologies such as the Rockies. (That mountain range has
been pushed, pulled, sheared, uplifted, eroded, and volcanically
exploded so many times it's not even funny.) They also have a
tendency to erode in straight lines, which only works if you have a
uniform lithological structure with no weakspots. (Faults, cracks,
fissures, stress fractures, joints.)

Now, I don't expect fully featured 3D, geologic perfection... most
users don't have that kind of computing power. (Days worth of
rendering even on a local scale with modern algorithms.) But is
there some way, other than trying to get the manual raising and
lowering tool to actually look like something other than play-dough on
top of it a very nice fractal render, to make these features less
'regular' and a little more representative of the actual geologies
involved? Has anyone tried to muck with this yet? Or am I the first
geologist to play around enough with this stuff to care? ;)
