Method Details

intersects

public static boolean intersects(Rectangle2D_I32 a,
 Rectangle2D_I32 b)

Checks to see if the two rectangles intersect each other

Parameters:

a - Rectangle

b - Rectangle

Returns:

true if intersection

intersection

public static boolean intersection(Rectangle2D_I32 a,
 Rectangle2D_I32 b,
 Rectangle2D_I32 result)

Finds the intersection between two rectangles. If the rectangles don't intersect then false is returned.

Parameters:

a - Rectangle

b - Rectangle

result - Storage for the found intersection

Returns:

true if intersection

containsConvex

public static boolean containsConvex(Polygon2D_I32 polygon,
 Point2D_I32 pt)

Checks to see if the point is contained inside the convex polygon. If the point is an the polygon's perimeter it is considered to NOT be inside.

Parameters:

polygon - Convex polygon. Not modified.

pt - Point. Not modified.

Returns:

True if the point is contained inside the polygon.

containsConcave

public static boolean containsConcave(Polygon2D_I32 polygon,
 Point2D_I32 pt)

Checks to see if the point is contained inside the concave polygon. NOTE: Points which lie along the perimeter may or may not be considered as inside

Parameters:

polygon - Convex polygon. Not modified.

pt - Point. Not modified.

Returns:

True if the point is contained inside the polygon.

contains

public static boolean contains(RectangleLength2D_I32 a,
 int x,
 int y)

True if the point is contained inside the rectangle

Parameters:

a - Rectangle

x - x-coordinate of point

y - y-coordinate of point

Returns:

true if the point is inside and false it is not

contains

public static boolean contains(Rectangle2D_I32 a,
 int x,
 int y)

True if the point is contained inside the rectangle

Parameters:

a - Rectangle

x - x-coordinate of point

y - y-coordinate of point

Returns:

true if the point is inside and false it is not
