Here is an image created with a function pattern.
The source of the texture is following. FN is a cyclic
function in this case (0<=FN(x,y,z)<1).
texture{
pigment{ function {FN(x,y,z)+abs(f_noise3d(x*12,y*12,z*12)-0.5)*0.8}
color_map{
[0 color <0,0.3,0.5>*.35] [.25 color <1,1,1>*.4]
[.5 color <1,0.8,0.6>*.6] [.75 color <0.6,1,0.8>*.8]
[1 color <0.5,0.3,0.7>*.75]
}
}
normal{ function {FN(x,y,z)}
slope_map{
[0, <0,1>] [0.5, <1,-1>] [1, <0,1>]
}
}
finish{phong 0.60 phong_size 90}
}
