triangulation

Triangulate polyshape

Syntax

T = triangulation(polyin)

Description

T = triangulation(polyin) returns a 2-D triangulation object of a polyshape object. T has properties that describe the vertices and connectivity of triangles that make up polyin. For more information, see triangulation.

Examples

Polygon Triangulation

Create and triangulate a polygon.

t = 0.05:0.5:2*pi;
x1 = cos(t);
y1 = sin(t);
x2 = 0.5*cos(t);
y2 = 0.5*sin(t);
polyin = polyshape({x1,x2},{y1,y2})

polyin = 
  polyshape with properties:

      Vertices: [27x2 double]
    NumRegions: 1
      NumHoles: 1

plot(polyin)

T = triangulation(polyin)

T = 
  triangulation with properties:

              Points: [26x2 double]
    ConnectivityList: [26x3 double]
