TriangleGetPoints

TriangleGetPoints[expr]

returns the points in a Triangle expression.

Details and Options

To use TriangleGetPoints, you first need to load it using Needs["TriangleLink`"].
The points returned from a Triangle expression are a list of coordinates.
A Triangle expression can have points loaded by TriangleSetPoints or created by TriangleTriangulate.
The memory used by a Triangle expression to hold points and other resources is cleared when you use TriangleDelete.

First, load the package:

Wolfram Language code: Needs["TriangleLink`"]

This creates an instance of a Triangle expression:

Wolfram Language code: inst = TriangleCreate[]

These are points to load to the instance:

Wolfram Language code: pts = {{0., 0.}, {2., 0.}, {2., 2.}, {0., 2.}};

This loads the points to the instance:

Wolfram Language code: TriangleSetPoints[inst, pts]

This retrieves the points from the instance:

Wolfram Language code: TriangleGetPoints[inst]
