TernaryMeshVertices: Vertex Coordinates of Sub-Triangles in Segmented Equilateral Triangle

Description

Given the barycentric centroid coordinates of the sub-triangles in an equilateral triangle subdivided into k^2 equilateral sub-triangles, return the barycentric vertex coordinates of each sub-triangle.

Usage

TernaryMeshVertices(C)

Arguments

C

n by 4 matrix of barycentric centroid coordinates of n=k^2 sub-triangles. Column order: id, p1, p2, p3 with id=1,...,k^2.

k

Number of rows in the segmented equilateral triangle.

Value

A numeric matrix with index, vertex id and barycentric vertex coordinates for each of the k^2 sub-triangles.
