<div dir="ltr"><div><div><div><div><div><div>Hello,<br><br></div>I'm working on
creating a mesh of terrain. I have 3D scatter data specifying points of
terrain elevation (DEM or Digital Elevation Model).<br><br></div>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.<br><br></div>Eventually, I will have multiple of these surfaces be the surface loop for a volume.<br><br></div>Any ideas how to accomplish this?<br><br></div>Thanks,<br></div>Matt</div>
