step3:
f_disturb_bump(x,y,z) is another bumps pattern (It has two frequency). I wish
use it to disturb the "f_test" function, so I tried some combine method + - *
/...
And this one is awesome. When I see I feel... great.
#declare f_output2 =
function(x, y, z) {
f_test(
x , y,
pow(
(x*x + y*y)/ (f_disturb_bump(x, y, z)+1)
, 0.75)
)
}
