I found a sort of "gold mine" with displacement warps on MegaPOV. Here I
used a wrinkles pattern as base, displaced with a "sandwich" of several
other patterns:
#declare fh=rand(r_terrf)*1000;
#local fn_Form=
function {
pattern{
wrinkles scale 10
warp {
displace {
gradient y
pigment_map{
[0.0 granite
scale <3*rand(r_terrf),3*rand(r_terrf),3*rand(r_terrf)>
rotate 360*rand(r_terrf)]
[0.2 bumps
scale <3*rand(r_terrf),3*rand(r_terrf),3*rand(r_terrf)>
rotate 360*rand(r_terrf)]
[0.4 crackle
scale <3*rand(r_terrf),3*rand(r_terrf),3*rand(r_terrf)>
rotate 360*rand(r_terrf)]
[0.6 dents
scale <3*rand(r_terrf),3*rand(r_terrf),3*rand(r_terrf)>
rotate 360*rand(r_terrf)]
[0.8 leopard
scale <3*rand(r_terrf),3*rand(r_terrf),3*rand(r_terrf)>
rotate 360*rand(r_terrf)]
[1.0 granite
scale <3*rand(r_terrf),3*rand(r_terrf),3*rand(r_terrf)>
rotate 360*rand(r_terrf)]
}
warp{turbulence Terrain_Turb}
scale <10,2.5,10>
rotate 360*rand(r_terrf)
}
}
}
}
#local fn_Terrain=
function {
y
- fn_Form(x, fh, z)*Terrain_Height
- fn_Form(x*10, y*10, z*10)*Terrain_Height*.05
- fn_Form(x*100, y*100, z*100)*Terrain_Height*.005
}

Wow yes excellent and rich vein!
I'll have a close look to your code ASAP
Congrats for your 2nd POVComp place :)

Yes! Me too, coincidently. Though I think rugged landscapes are a more
satisfying application than Boli mud. LOL! But I really was trying to
find ways to vary scale within a texture. Like on crocodile skin,...or
leather ;)

wow, the formation of the land is great. very believable. the render quality
however... look svery grainy and washed out.
seriously, it's hard to believe that the terrain wasn't meticulously carved
by the old guy in Hitchhikers Guide to the Galaxy who created the coastlines
of earth. amazing work.

These (displacement warp landscapes) are just phenomenal. I hope I get some
time in the next few months to
sit down and puzzle out what's going on and why it works so well (I mean,
besides the fact that your stuff is always great and you really know what
you're doing.)

Every time I feel I've done something cool in Povray Jaime comes along and I
see just how far I still have to go... :)

Looks almost exactly like a photo I took on my last vacation.

You can check his name and portrait in a glacier in Norway.
