And you completely took away our saying we are green with envy...
These look great and are much more detailed with respect to the head
shape than what I did with the ghost image. As to your last statement
about warp { turbulence }, remember Jamie's trick to scale turbulence
with respect to an object/pattern. It is a trick I used in the ghost
image. Namely:
// Credit: Jaime Vives Piqueres for warp turbulence scaling. Tierra zip.
www.ignorancia.org.
#macro WarpShapesA_2 ()
scale 1.0/0.9000
warp {
turbulence 0.1500
octaves 6
lambda 2.0000
omega 0.6500
}
scale 0.9
#end
So to have a lot of scaled down, but heavier, turbulence, you first
scale the "thing" up, apply the turbulence warp, then scale everything
back to the original size.
