EarClippingTriangulator (gdx 1.12.1 API)

java.lang.Object
- com.badlogic.gdx.math.EarClippingTriangulator

```
public class EarClippingTriangulator
extends java.lang.Object
```
A simple implementation of the ear cutting algorithm to triangulate simple polygons without holes. For more information:

- http://www.geometrictools.com/Documentation /TriangulationByEarClipping.pdf
If the input polygon is not simple (self-intersects), there will be output but it is of unspecified quality (garbage in, garbage out).
If the polygon vertices are very large or very close together then GeometryUtils.isClockwise(float[], int, int) may not be able to properly assess the winding (because it uses floats). In that case the vertices should be adjusted, eg by finding the smallest X and Y values and subtracting that from each vertex.

```
    Triangulates the given (convex or concave) simple polygon to a list of triangle vertices.
    
    Parameters:
    
    vertices - pairs describing vertices of the polygon, in either clockwise or counterclockwise order.
    
    Returns:
    
    triples of triangle indices in clockwise order. Note the returned array is reused for later calls to the same method.
