Tetgen with just points
by Matthew B
Hello all,
I am trying to make a hollow 3D dome (just triangles, not tets) by placing
points around a circle and then random points on the dome. I don't want to
keep up with all of the facets. I basically have two problems:
1) I am able to do with with tetgen on the command line by just
concatenating the .node file I create with the .face file it creates, but
there is a bottom to the dome.
2) If I try to use meshpy with just points using
mesh_info = MeshInfo()
mesh_info.add_points(points)
mesh = build(info)
Then np.array(mesh.facets) and np.array(mesh.points) are both empty.
I know there are ways to keep up with the facets, but I have been wanting
to use meshpy with just points for awhile now, so I wanted to see if I was
missing anything. Thanks to all who took the time to read! Any help is
greatly appreciated.
