pub struct Point(_);

A point with two coordinates.

Implementations

impl Point

pub fn distance(&self, b: &Point) -> (f32, f32, f32)

Computes the distance between self and b.

b

a Point

Returns

the distance between the two points

d_x

distance component on the X axis

d_y

distance component on the Y axis

pub fn init(&mut self, x: f32, y: f32)

Initializes self to the given x and y coordinates.

It’s safe to call this function multiple times.

x

the X coordinate

y

the Y coordinate

Returns

the initialized point

pub fn init_from_point(&mut self, src: &Point)

Initializes self with the same coordinates of src.

src

the Point to use

Returns

the initialized point

pub fn init_from_vec2(&mut self, src: &Vec2)

Initializes self with the coordinates inside the given Vec2.

src

a Vec2

Returns

the initialized point

pub fn interpolate(&self, b: &Point, factor: f64) -> Point

Linearly interpolates the coordinates of self and b using the given factor.

b

a Point

factor

the linear interpolation factor

Returns

res

return location for the interpolated point

pub fn near(&self, b: &Point, epsilon: f32) -> bool

Checks whether the two points self and b are within the threshold of epsilon.

b

a Point

epsilon

threshold between the two points

Returns

true if the distance is within epsilon

pub fn to_vec2(&self) -> Vec2

Stores the coordinates of the given Point into a Vec2.

Returns

v

return location for the vertex

pub fn zero() -> Point

Returns a point fixed at (0, 0).

Returns

a fixed point

impl Point

pub fn new(x: f32, y: f32) -> Point

pub fn from_point(src: &Point) -> Point

pub fn from_vec2(src: &Vec2) -> Point

Trait Implementations

impl Clone for Point

fn clone(&self) -> Point

Returns a copy of the value.

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