A rapid test here :-)
#declare F_HF_01 =
function {
pigment {
image_map {png "And_Concentric pattern.png" gamma 1.0
map_type 0
interpolate 2
}
scale 2
translate -0.5
}
}
height_field {
function 2000, 2000 {F_HF_01(x,y,z).hf}
pigment {gradient y pigment_map {[0.0 rgb <0,0.2,0>][1.0 rgb <1,1,0>]}}
finish {diffuse 0.8 specular 0.1 roughness 0.001}
scale <500, 50/7.5, 500>
translate <-500/2, 0, -500/2>
scale <1, 1, -1>
