HCoordinate class

Represents a homogeneous coordinate in a 2-D coordinate space. In JTS {@link HCoordinate}s are used as a clean way of computing intersections between line segments.

Constructors

HCoordinate()
HCoordinate.c(Coordinate p)
HCoordinate.from2c(Coordinate p1, Coordinate p2)
Constructs a homogeneous coordinate which is the intersection of the lines define by the homogenous coordinates represented by two {@link Coordinate}s.
