Class Inclusive2DIntersectionVerifier

java.lang.Object
  cmsc420.geom.Inclusive2DIntersectionVerifier

public class Inclusive2DIntersectionVerifier
extends java.lang.Object

The InclusiveIntersectionVerifier class provides static methods used to determine if two shapes intersect. Unlike the java.awt.geom methods, bounds are included in all intersection checks.

Method Summary

static boolean	intersects(Circle2D c1, Circle2D c2) Returns true if a circle intersects with another circle.
static boolean	intersects(java.awt.geom.Line2D seg1, java.awt.geom.Line2D seg2) Returns true if two line segments intersect.
static boolean	intersects(java.awt.geom.Line2D seg, java.awt.geom.Rectangle2D rect) Returns true if any part of a segment intersects inclusively within the rectangle's bounds.
static boolean	intersects(java.awt.geom.Point2D point, Circle2D circle) Returns true if a point lies inclusively within a circle's bounds.
static boolean	intersects(java.awt.geom.Point2D point, java.awt.geom.Line2D line) Returns true if a point intersects with a line segment.
static boolean	intersects(java.awt.geom.Point2D pt1, java.awt.geom.Point2D pt2) Returns true if a point intersects with another point.
static boolean	intersects(java.awt.geom.Point2D point, java.awt.geom.Rectangle2D rect) Returns true if a point lies inclusively within a rectangle's bounds.
static boolean	intersects(java.awt.geom.Rectangle2D rect, Circle2D circle) Returns true if a rectangle and circle intersect.
