In p.u.p, we were discussing options for getting a plateau-free noise
function for pov. I was experimenting with the pattern-based pigments
in isosurfaces and wonder if I found something in dents.
The "dents" pattern below almost looks plateau-free, although not
exaclty "smooth" as the ideal function I'm looking for would have.
"Bumps" has plateaus. So how are dents and bumps different?
[This same text and actual images in p.b.i].
// switch to DENTS here
#declare yikes=function{pigment {bumps scale 30}}
#declare funk=
isosurface{
function{
y/100+yikes(x,y,z)/2}
sign 1
accuracy 0.01
threshold 1
clipped_by
{ sphere{0,250}}
}
