Class IntersectionDescriptor

java.lang.Object

com.amalgamasimulation.geometry.IntersectionDescriptor

public class IntersectionDescriptor
extends Object

Class representing all contextual information about one intersection point of two geometric primitives, each of them can be a Point, a Segment, or a Polyline.

This class stores the intersection Point itself, as well as absolute and relative offsets of this point on both intersection operands.
