Work with relief

Hello everybody
Found a video by Mariusz Hermansdorfer.
I am interested in how the relief is reconstructed and how the trimmed area is distinguished by color.
I have an algorithm for building relief from the created points, but I don’t know how to separate the clipped relief.
Thank you.

The deformation in the video was made with a surface attractor.

Thanks, I’ll try your option.
How is the changed geometry colored in your version?

Search the forum to get knowledge on how to add color attributes to a mesh.

Unfortunately, I did not find what I needed on the forum.
