Method Detail

intersect

public static void intersect(IRectangle src1,
                             IRectangle src2,
                             Rectangle dst)

Intersects the supplied two rectangles, writing the result into dst.

union

public static void union(IRectangle src1,
                         IRectangle src2,
                         Rectangle dst)

Unions the supplied two rectangles, writing the result into dst.

closestInteriorPoint

public static Point closestInteriorPoint(IRectangle r,
                                         IPoint p,
                                         Point out)

Computes the point inside the bounds of the rectangle that's closest to the given point, writing the result into out.

Returns:

out for call chaining convenience.

closestInteriorPoint

public static Point closestInteriorPoint(IRectangle r,
                                         IPoint p)

Computes and returns the point inside the bounds of the rectangle that's closest to the given point.

pointRectDistanceSq

public static float pointRectDistanceSq(IRectangle r,
                                        IPoint p)

Returns the squared Euclidean distance between the given point and the nearest point inside the bounds of the given rectangle. If the supplied point is inside the rectangle, the distance will be zero.

pointRectDistance

public static float pointRectDistance(IRectangle r,
                                      IPoint p)

Returns the Euclidean distance between the given point and the nearest point inside the bounds of the given rectangle. If the supplied point is inside the rectangle, the distance will be zero.
