 Dear developer,

 I am using Scipy.spatial.Delaunay to do some analysis.
 I found that the Delaunay model can not produce the tetrahedron for
 my simulated 3D particles which is at the center of a halo. Lots of it do
 not include in the tri.vertices. For example, I select about ~2300
 particles in the center, and do the triangulation. But the tri.vertices
 only have a shape of (484, 4)! I think this should be a problem of the
 Hull's accuracy setting. Can I know where I can tune this?
 Thanks.
 ilaudy
