[Gmsh] Generation of Irregular 3D Surface (From DEM or xyz)

Hello,

I'm working on creating a mesh of terrain. I have 3D scatter data
specifying points of terrain elevation (DEM or Digital Elevation Model).

Instead of having Gmsh use every point as a node for triangulation, I'd
like the scatter data be used as a constraint - perhaps the nodes would be
linearly interpolated between the known scatter data.

Eventually, I will have multiple of these surfaces be the surface loop for
a volume.

Any ideas how to accomplish this?

Thanks,
Matt
