TriangleSetSegments

TriangleSetSegments[expr]

sets the segments for a Triangle expression.

Details and Options

To use TriangleSetSegments, you first need to load it using Needs["TriangleLink`"].
TriangleSetSegments indicates to Triangle where a segment located in a mesh.

First, load the package:

Wolfram Language code: Needs["TriangleLink`"]

This creates an instance of a Triangle expression:

Wolfram Language code: inst = TriangleCreate[]

This sets up points and facets to use:

Wolfram Language code:

pts = {{0., 0.}, {2., 0.}, {2., 2.}, {0., 1.}};
segments = {{1, 2}, {2, 3}, {3, 4}, {4, 1}};

This sets the points and facets in the Triangle instance:

Wolfram Language code:

TriangleSetPoints[inst, pts];
TriangleSetSegments[inst, segments];

This extracts the segments again:

Wolfram Language code: TriangleGetSegments[inst]
