You can see the directions the verts would be pushed in this demo:
Directions

So, I’m not pushing the verts in this, just showing the directions you get from the doublecross.
As you can see, overhangs does not work great so you’ll need to do some if stuff and invert the direction in some cases.

Harmonic Attenuation func:

cos((1 / 2) * Pi * x / L) ^ m * cos(2 * Pi * n * x / L)

L - lenght
x - value [0, L]
m - attenuation power
n - number of waves
