## Package math.geom2d.polygon Description

Definitions and implementations of shapes composed several line segments: polylines, rings, polygons. Contains several polygon implementations, to manage the different types of polygons.

Package organization:

- Polygons:
- Polygon2D: main interface for all polygonal shapes
- SimplePolygon2D: implementation for simply connected polygons
- MultiPolygon2D: implementation for polygons composed of several pieces

- Polylines:
- LinearCurve2D: abstract class for any type of polyline
- Polyline2D: implementation for open polyline
- LinearRing2D: implementation for closed polylines, typically polygon boundaries

- Utility class:
- Polygons2D: utilities for polygons
- Polylines2D: utilities for polylines
