Interface PolygonalChain

All Known Implementing Classes:

PolygonalChainByArray

public interface PolygonalChain

A polygonal chain, polygonal curve, polygonal path, or piecewise linear curve, is a connected series of line segments. More formally, a polygonal chain P is a curve specified by a sequence of points called its vertices so that the curve consists of the line segments connecting the consecutive vertices.

This interface represents a polygonal chain, in an arbitrary dimensional Cartesian space. It is specified by a finite, ordered list of points.
