returns the facets for a TetGen expression.


  • To use TetGenGetFacets, you first need to load it using Needs["TetGenLink`"].
  • Each facet is a list of indices into the point specification.
  • Each facet represents a polygonal region. It may have any number of sides and may be nonconvex, possibly with holes, segments, and vertices in it.
  • Each facet must be coplanar.

First, load the package:

This finds a sample data file in the TetGenLink installation:

To load the data file, you must first create an instance of a TetGen expression to hold the result:

This loads the data file into the instance:

This extracts the points from the instance:

This extracts the vertices from the instance:

Here, the shape is plotted:
