Class PolygonTriangulator

Computes a triangulation of each polygon in a {@link Geometry}. A polygon triangulation is a non-overlapping set of triangles which cover the polygon and have the same vertices as the polygon. The priority is on performance rather than triangulation quality, so that the output may contain many narrow triangles.

Holes are handled by joining them to the shell to form a (self-touching) polygon shell with no holes. Although invalid, this can be triangulated effectively.

For better-quality triangulation use ConstrainedDelaunayTriangulator.
