colored elevation map from STL file

Hi everyone,

I'd like to vizualise the distorsions in a welded plate.

I scanned with Alicona the surface of the plate and I got a STL file (and the corresponding .txt file with coordinates).

I don't know how to get a colored elevation map from this STL file. To be clear, I'd like to obtain something like that:

Do you know how to do it in matlab?

Thanks for your help

A simple example

unzip pringle_top.stl.zip
T = stlread('pringle_top.stl');

trisurf(T);
shading flat; view(10,33)
axis equal; grid on
xlabel('X'); ylabel('Y'); zlabel('Z')
colorbar
