Implementations

impl Point

pub const ZERO: Point

The point (0, 0).

pub const ORIGIN: Point

The point at the origin; (0, 0).

pub const fn new(x: f64, y: f64) -> Self

Create a new Point with the provided x and y coordinates.

pub const fn to_vec2(self) -> Vec2

Convert this point into a Vec2.

pub fn lerp(self, other: Point, t: f64) -> Point

Linearly interpolate between two points.

pub fn midpoint(self, other: Point) -> Point

Determine the midpoint of two points.

pub fn distance(self, other: Point) -> f64

Euclidean distance.

pub fn round(self) -> Point

Returns a new Point, with x and y rounded to the nearest integer.

Examples

use kurbo::Point;
let a = Point::new(3.3, 3.6).round();
let b = Point::new(3.0, -3.1).round();
assert_eq!(a.x, 3.0);
assert_eq!(a.y, 4.0);
assert_eq!(b.x, 3.0);
assert_eq!(b.y, -3.0);

pub fn ceil(self) -> Point

Returns a new Point, with x and y rounded up to the nearest integer, unless they are already an integer.

Examples

use kurbo::Point;
let a = Point::new(3.3, 3.6).ceil();
let b = Point::new(3.0, -3.1).ceil();
assert_eq!(a.x, 4.0);
assert_eq!(a.y, 4.0);
assert_eq!(b.x, 3.0);
assert_eq!(b.y, -3.0);

pub fn floor(self) -> Point

Returns a new Point, with x and y rounded down to the nearest integer, unless they are already an integer.

Examples

use kurbo::Point;
let a = Point::new(3.3, 3.6).floor();
let b = Point::new(3.0, -3.1).floor();
assert_eq!(a.x, 3.0);
assert_eq!(a.y, 3.0);
assert_eq!(b.x, 3.0);
assert_eq!(b.y, -4.0);

pub fn expand(self) -> Point

Returns a new Point, with x and y rounded away from zero to the nearest integer, unless they are already an integer.

Examples

use kurbo::Point;
let a = Point::new(3.3, 3.6).expand();
let b = Point::new(3.0, -3.1).expand();
assert_eq!(a.x, 4.0);
assert_eq!(a.y, 4.0);
assert_eq!(b.x, 3.0);
assert_eq!(b.y, -4.0);

pub fn trunc(self) -> Point

Returns a new Point, with x and y rounded towards zero to the nearest integer, unless they are already an integer.

Examples

use kurbo::Point;
let a = Point::new(3.3, 3.6).trunc();
let b = Point::new(3.0, -3.1).trunc();
assert_eq!(a.x, 3.0);
assert_eq!(a.y, 3.0);
assert_eq!(b.x, 3.0);
assert_eq!(b.y, -3.0);
