[Gmsh] Creating 3D geometry

[Max Orok]

Hi Deepa,

This is sort of a half-baked idea, but if you could get the positions of a
bunch of center points,
maybe you could add lines between them and use that as a sort of extrude
profile for whatever shape you want to use.

You can base a mesh off of a picture's colour, so maybe that's a good way
to get some centerline points.
There is a picture example here that might be helpful

Sincerely,
Max
