Thanks for your reply!

The maximum in this particular case can't be 34.5012, as plugging <1,0,0,> into
the function results in a value of 3.808.

I was hoping for a general method that I could apply anywhere, but I see now
that there could possibly be multiple maximums--or no maximum at all!--unless a
strict range were also given. This is not an issue in this case, however, since
the function is not continuous.

Through trial and error I came up with an equation that is pretty close (less
than 1% error in many cases), but is still in need of some work:

#declare max_value = pow(Blob_threshold,-pow(Blob_radius,2))/2 +
pow(Blob_threshold,-pow(Blob_radius,2))/2
