Oops! I made a mistake when copying the function. Here's the actual code:

#local Temp_fnc1 = function
{
	1 - min(1, sqrt(x*x + y*y + z*z))
}
#local Temp_fnc3 = function
{
	max(0,min(1,Temp_fnc1(x, log(y + 1) / log(2),z)))
}

And the warp:

warp
{
	turbulence	<1/4,1/64,1/4,>
	octaves		4
	lambda		2
	omega		1/2
}
