You may use MITK to create iso-surface from volumetric images e.g. CT-scans.

I am trying to generate the surface mesh of a 3D binary segmented volumetric
label(the voxel value is 0 and 1) using the code in
Surface_mesher/mesh_a_3d_gray_image.cpp
<https://doc.cgal.org/latest/Surface_mesher/Surface_mesher_2mesh_a_3d_gray_image_8cpp-example.html>
. When I tried different isovalues ranging from 0.1-0.9, I get different
surface meshes with different vertices and facets.

It seems that the the isovalues was used to get the signs of f(p)-isovalue,
but what is the function f and how the isovalue can impact the meshing
result?

Thank you.
