func Adjacency Uses

func Adjacency(r1, r2 Rectangle) bool

Adjacency detects whether two rectangles, r1, and r2, are adjacent. Adjacency is defined as the sharing of a side

func Containment Uses

func Containment(r1, r2 Rectangle) bool

Containment returns whether r2 is contained inside of r1

func Intersection Uses

func Intersection(r1, r2 Rectangle) []Point

Intersection determine whether two rectangles, r1 and r2, have one or more intersecting lines and produce a result, []Point, identifying the points of intersection

type Point Uses

type Point struct {
    X, Y float64

Point is a struct defining a coordinates position on a 2D plane

type Rectangle Uses

type Rectangle struct {
    P1, P2, P3, P4 Point

Rectangle struct defines a plane figure with four straight sides and four right angles, which contains 4 vertixes points, P1 through P4

func (Rectangle) IsRect Uses

func (r Rectangle) IsRect() bool

IsRect determins if the rectangle provided really is a rectangle, which by definition means a plane figure with four straight sides and four right angles.
