How can I plot a 3D displacement field from scattered data?

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

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.

Maybe I was not clear..
the plot I have there that is what I want and thank you for that. But the data I have is not ideal because of the set up method..
What I want now is to rotate the plot or 'drag' the plot to the Plane XY.. As you can see the surfaces I have are in the space in obliquous position all I want is the surfaces to be horizontal or paralel to plane xy. (I.e. Blue plane co-planar or paralel to plane XY)
Best regards

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