Struct Point2 

pub struct Point2 {
    pub x: f64,
    pub y: f64,
}

A 2-D point / vector.

Fields

x: f64

X coordinate.

y: f64

Y coordinate.

Implementations

impl Point2

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

Create a new point.

pub fn zero() -> Self

Zero vector.

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

Euclidean distance to another point.

pub fn length(&self) -> f64

Length (norm) of the vector.

pub fn normalized(&self) -> Self

Normalise to unit length. Returns zero if degenerate.

pub fn dot(&self, other: &Self) -> f64

Dot product.

pub fn cross(&self, other: &Self) -> f64

2-D cross product (scalar).

pub fn perp(&self) -> Self

Perpendicular (rotate 90 degrees CCW).

pub fn add(&self, other: &Self) -> Self

Add two points.

pub fn sub(&self, other: &Self) -> Self

Subtract.

pub fn scale(&self, s: f64) -> Self

Scale.

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

Lerp between self and other.

pub fn angle(&self) -> f64

Angle in radians (atan2).

pub fn from_polar(angle: f64, length: f64) -> Self

Create from angle and length.

Trait Implementations

impl Clone for Point2

fn clone(&self) -> Point2

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Point2

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Point2

fn eq(&self, other: &Point2) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
