TetGenSetPointMarkers

TetGenSetPointMarkers[expr,markers]

sets the point markers in a TetGen expression.

Details and Options

  • To use TetGenSetPointMarkers, you first need to load it using Needs["TetGenLink`"].
  • TetGenSetPointMarkers allows you to set markers for points in a TetGen instance.

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 the point and facet markers:

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

This carries out the tetrahedralization, returning a new TetGen instance:

Wolfram Language code: outInst = TetGenTetrahedralize[ inst, "pqa0.1"]

This extracts the points and elements from the tetrahedralization:

Wolfram Language code: coords = TetGenGetPoints[outInst];

This visualizes the points:

Wolfram Language code: Graphics3D[Point[coords], Boxed -> False]

This extracts the point markers:

Wolfram Language code: coordsMarkers = TetGenGetPointMarkers[outInst]

This visualizes some of the surface points:

Wolfram Language code: selectedPoints = {43, 66} Graphics3D[Point[ Pick[coords, coordsMarkers, #] ]& /@ selectedPoints]
