Conform Points To Background Layer's Mesh Surface

[SA9R]

What is the easiest way to conform that points in a foreground layer to the mesh surface of a background layer?

It should achieve the same effect as in the GIF below.

The background mesh needs enough divisions though for the points to conform smoothly.

There is a a commercial advanced heatshrink plus from 3rd powers also, but natively you could try the free options first.

Thank you. I tried that again, and it worked because I had to set parameters to:
Offset: 0
Mode: Y

Otherwise, before, I was not getting exactly the right shape or it was distorting the splines. Actually, both.

Yes...for many cases you would use sphere or normals, but it would distort it in other directions, so correct, Y-direction mode it should be in this case, you only want deform on that axis since you have a curve that needs to maintain it´s shape in the other directions.

RMB to adjust tolerance,
then LMB in the perspective viewport project points from fg layer to bg layer.
Eventually move mouse holding LMB, to slide them conforming to the background layer.
