Automatic recreating wave relief from existing splines

[laurent_delrieu]

Here one way to do

I divide each curve, put a line between the 2 borders, it gives me a middle point and a length (useful to move down the point)
Then evaluate each length of line, use Graph Mapper to scale the movement in Z depending on the normalized length of lines, the move the middle point then make a curve

Stacking curves (How To)

Here a little script that enables to stack curves without (or quite) intersections.It was done to answer a question on this forum but as the one who asked doesn’t care I post it here [wavy curves] [wavy curves2] [wavy curves31] The logic is simple Make a list of curve with same extension on X and Y. I used 4Dnoise here. [image] Divide the curves in points (400 points here) and find the minimum distance between 2 consecutive curves. [image] Moves the curves UP [image] wavy curve…
