Class HCoordinate

Hierarchy: Object , HCoordinate

public class HCoordinate

Represents a homogeneous coordinate in a 2-D coordinate space. In JTS HCoordinates are used as a clean way of computing intersections between line segments.

public HCoordinate(HCoordinate p1, HCoordinate p2)

public HCoordinate(Coordinate p1, Coordinate p2)

Constructs a homogeneous coordinate which is the intersection of the lines define by the homogenous coordinates represented by two Coordinates.

Parameters:: p1 - p1; p2 - p2

public HCoordinate(Coordinate p1, Coordinate p2, Coordinate q1, Coordinate q2)

public static Coordinate intersection(Coordinate p1, Coordinate p2, Coordinate q1, Coordinate q2)

Computes the (approximate) intersection point between two line segments using homogeneous coordinates.

Note that this algorithm is not numerically stable; i.e. it can produce intersection points which lie outside the envelope of the line segments themselves. In order to increase the precision of the calculation input points should be normalized before passing them to this routine.
