TetGenExport["file.ext",expr]

exports data from a TetGen expression into a file.

TetGenExport["file",expr,"format"]

exports data in the specified format.

Details and Options

  • To use TetGenExport, you first need to load it using Needs["TetGenLink`"].
  • TetGenExport[File["path"],expr] is also supported.
  • The following formats specific to TetGen are supported by TetGenExport:
  • "node"a list of nodes
    "poly"a list of facets
    "smesh"a simple piecewise linear complex
    "ele"a list of tetrahedra
    "face"a list of triangular faces
    "edge"a list of boundary faces
    "neigh"a list of neighbors

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];

Here is a file name to take the "poly" data:

Wolfram Language code: file = FileNameJoin[{$TemporaryDirectory, "temp.poly"}];

This saves the data into the file:

Wolfram Language code: TetGenExport[file, inst]

This shows the contents of the file:

Wolfram Language code: FilePrint[file]

Here is a new file name to take the "node" data:

Wolfram Language code: file = FileNameJoin[{$TemporaryDirectory, "temp.node"}];

This saves the data into the file:

Wolfram Language code: TetGenExport[file, inst]

This shows the contents of the file:

Wolfram Language code: FilePrint[file]
