type OrientationKind Uses

type OrientationKind int

OrientationKind indicates how three points are located in respect to each other.

const (
    // Counterclockwise
    CCW OrientationKind = iota
    // Clockwise

func Orientation Uses

func Orientation(x1, y1, x2, y2, x, y float64) OrientationKind

Orientation returns how the point (x,y) is oriented with respect to the line defined by the points (x1,y1) and (x2,y2).

func (OrientationKind) String Uses

func (o OrientationKind) String() string

type RelativePosition Uses

type RelativePosition int

RelativePosition is the position of a point relative to a circle

const (
    // Inside the circle
    Inside RelativePosition = iota
    // On the circle
    // Outside the circle

func Incircle Uses

func Incircle(x1, y1, x2, y2, x3, y3, x, y float64) RelativePosition

Incircle determines the relative position of the point (x,y) in relation to the circle formed by the three points (x1,y1),(x2,y2) and (x3,y3). The three points have to be ordered counterclockwise or Outside and Inside will be reversed.

func (RelativePosition) String Uses

func (p RelativePosition) String() string
