utils

Pnt2 (class)

Signature

export declare class Pnt2

clone (static method)

clone point

Signature

static clone(p: Point2): Point2

spr (static method)

spread point components

Signature

static spr(p: Point2): [number, number]

neg (static method)

get negation of the point

Signature

static neg(p: Point2): Point2

add (static method)

add point b to point a

Signature

static add(a: Point2, b: Point2): Point2

sub (static method)

subtract point b from point a
