You might want to consider a different approach. This one comes to mind:

Gradient of points between two curves

It occurs to me that adding a Graph Mapper can magnify the effect of distance from the boundary: [gradient_points_2020Apr6a] gradient_points_2020Apr6a.gh (13.6 KB)

Gradient Point Clouds

Whereas adapting the model I posted to 3D isn’t all that difficult. Took only a few minutes. [gradient_points_2020May14a] gradient_points_2020May14a.gh (24.3 KB)
