TetGenSetFacets

TetGenSetFacets[expr,vertices]

sets the facets for a TetGen expression.

Details and Options

  • To use TetGenSetFacets, 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.

Examples

Basic Examples  (1)

First, load the package:

Wolfram Language code: Needs["TetGenLink`"]

This creates an instance of a TetGen expression:

Wolfram Language code: inst = TetGenCreate[]

This loads points into the TetGen expression:

Wolfram Language code: pts = {{0., 0., 0.}, {2., 0., 0.}, {2., 0., 2.}, {0., 0., 2.}, {0., 12., 0.}, {2., 12., 0.}, {2., 12., 2.}, {0., 12., 2.}}; TetGenSetPoints[inst, pts];

This defines and loads facets into the TetGen expression:

Wolfram Language code: verts = {{{1, 2, 3, 4}}, {{5, 6, 7, 8}}, {{1, 5, 6, 2}}, {{2, 6, 7, 3}}, {{3, 7, 8, 4}}, {{4, 8, 5, 1}}};TetGenSetFacets[inst, verts];

The following plots the shape that was loaded into a TetGen expression:
