3d grid distortion / attractor point on curve 3d grid

[Joseph_Oster]

The edge damping (white group) can be minimized or ignored. As I recall, this might work better with Nurbs curves instead of IntCrv?

Nurbs Curves for Grid Distortion in 3 Dimensions

P.S. Adapted to a 3D grid (using interpolated curves instead of NURBs curves, but you can easily change that), with a switch (blue group) to enable/disable edge damping: [nurbs grid_2021May13a] nurbs grid_2021May13a.gh (30.2 KB)
