TetGenGetEdges

TetGenGetEdges[expr]

gets the edges in a TetGen expression.

Details and Options

  • To use TetGenGetEdges, you first need to load it using Needs["TetGenLink`"].
  • TetGenGetEdges returns the edges in a TetGenExpression.
  • TetGenGetEdges needs the "e" switch to be set during the call to TetGenTetrahedralize.

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[]

These are points and facets to load into the instance:

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.}}; facets = {{{1, 2, 3, 4}}, {{5, 6, 7, 8}}, {{1, 5, 6, 2}}, {{2, 6, 7, 3}}, {{3, 7, 8, 4}}, {{4, 8, 5, 1}}};

This loads the points and facets into the instance:

Wolfram Language code: TetGenSetPoints[inst, pts]; TetGenSetFacets[inst, facets];

The tetrahedralization is done with the "e" switch to trigger the computation of the edges:

Wolfram Language code: outInst = TetGenTetrahedralize[inst, "pe"]

This extracts and visualizes the edges:

Wolfram Language code: pts = TetGenGetPoints[outInst]; edges = TetGenGetEdges[outInst]; Graphics3D[GraphicsComplex[pts, Line[edges]], Boxed -> False]
