Is there any way I can access all the surface coordinates of an imported .stl file?

I would like to see all the surface values of my imported 3d model, like the ones displayed on the left.

[KSSV]

gm = importGeometry(myfile);
gm

Check the LHS gm it has all the data you want.

This? But I need all the X, Y and Z coordinates on the surface...

[KSSV]

p = Halbkugel.Vertices ; 
x = p(:,1); y = p(:,2) ; z = p(:,3) ;

I'm sorry for the miscommunication. My goal is to extract all of the coordinates marked in red:

[KSSV]

What is the creiteria to selecte those points?

[Seb]

data = stlread('HalbeKugel.stl');
s=trisurf(data,'FaceColor','none','EdgeColor','k')
axis equal

s.Vertices

x=s.Vertices(:,1)
y=s.Vertices(:,2)
z=s.Vertices(:,3)

I managed to get the coordinates. The goal is to determine the surfaces characteristics, e.g. the slope.

Thanks for the help so far.
