I am studying the deformation/distortion of a welded plate and I have a txt file with the displacement and coordinates of several points,
The data is obtained through an optical system and identifys points introduced in the plate.. I take two measurements one before welding as a reference and another after welding and the software stores coordinates and displacement of the several points detected in the plate in a txt file.
I wanted to do something similar to the attached file. I haven't started yet but I leave this question for some advice to know where to start.
Sincerely
Daniel Sousa

It looks like a surf plot. However you probably need scatteredInterpolant or its friends if you only have a few scattered values rather than a grid, or one of the gridded interpolation functions if your data are regularly-spaced on a grid to get the detailed surfaces in the attachment.

I’m still sort of lost.
One possibility (if I’m understanding you correctly — no promises there) is to use the rotate function.
