I need a function to use in densities that is like the existing spherical
density, but gets weaker based on the square of the distance instead of a linear
radius.

I couldn't find one in "functions.inc" unless I missed it.

Thanks!!

Something like this:

#declare f_Example = function{ 1/(x*x + y*y + z*z) }
