Dear Paraview users,
Based on the documentation, Delaunay3D will construct a 3D Delaunay
triangulation from a list of input points if alpha=0. But I did an
experiment that gave a different result. Here are the steps:
(1) Sources->Point source, and set Number of points to N (I experiment
with different N=5 and N=20)
(2) Using sphere glyph to display these points
(3) Apply filter "Delaunay 3D" to the points with alpha=0 and display
the resultant unstructured grid as wireframe.
When N=20, I can see some of the points are ignored in the process of
Delauney triangulation.
When N=5, The resultant unstructured grid has 3 cells while I think it
should have only 2 tetrahedra.
Can someone explain it? Thanks a lot.
Weiguang
