Function triangulateShape

Perform triangulation of a (2D) contour polygon with holes.

Example

ShapeUtils.triangulateShape( [
  new Vector2(10,0),  // 0
  new Vector2(0,50),  // 1
  new Vector2(60,60), // 2
  new Vector2(70,10)  // 3
], [])
// [ [ 1, 0, 3 ], [ 3, 2, 1 ] ]

Returns

The triangles over the contour (number[][3]). Each row is a triangle represented as a number[3] array where each value is an index in the contour array.
