Method Detail

intersect

public static boolean intersect(Line2D line0,
                                Line2D line1,
                                Point2D relativeLocation,
                                Point2D absoluteLocation)

Computes the intersection of the given lines.

Parameters:

line0 - The first line

line1 - The second line

relativeLocation - Optional location that stores the relative location of the intersection point on the given line segments

absoluteLocation - Optional location that stores the absolute location of the intersection point

Returns:

Whether the lines intersect
