TetGenGetFacetMarkers

TetGenGetFacetMarkers[expr]

returns the facet markers for a TetGen expression.

Details and Options

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 sets up points and facets to use:

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 sets the points and facets in the TetGen instance:

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

This sets facet markers:

Wolfram Language code: TetGenSetFacetMarkers[inst, {43, 66, 4, 2, 5, 3}];

This retrieves facet markers:

Wolfram Language code: TetGenGetFacetMarkers[inst]

Note that no facet markers are present in a tetrahedralized TetGen expression:

Wolfram Language code: out = TetGenTetrahedralize[ inst, "pq1.414a0.1"]; TetGenGetFacetMarkers[out]

Extract the face markers of a tetrahedralized TetGen expression:
