TetGenDelaunay

TetGenDelaunay[points]

generates a Delaunay tetrahedralization for a 3D point set.

Details

  • To use TetGenDelaunay, you first need to load it using Needs["TetGenLink`"].
  • TetGenDelaunay returns a list of points and tetrahedra.
  • TetGenDelaunay will find a tetrahedralization that connects all points.

To use TetGenLink it must first be loaded:

This creates some 3D data:

You can compute the Delaunay tetrahedralization of the data with TetGenDelaunay:

The result is a list of points and tetrahedra. The list of tetrahedra is a list of four integers that refer to the coordinate positions. To visualize the tetrahedra as a wireframe, you can use a supporting function:

To use TetGenLink it must first be loaded:

To compute the Delaunay tetrahedralization of the data, use TetGenDelaunay:

Note that the points returned need not be the same as the original input data:
