I just don't understand why not, pattern functions seemed the natural 
choice, and the function is quite simple. Maybe it would be more easily 
understood this way:


//clamps the value x to the range [y,z]
#declare clamp = function {max(y,min(z,x))}

//old style bozo, complete with plateaus
#declare OldBozo =
function {clamp(noise3d(x,y,z)/0.48985582 - 1.05242 + 0.5, 0, 1)}

Or are you talking about the "noise3d(x,y,z)/0.48985582 - 1.05242 + 0.5" 
part? That was just the mapping copied from Nathans post.
