Struct math2d::Point2f

#[repr(C)]
pub struct Point2f {
    pub x: f32,
    pub y: f32,
}

Mathematical point on the 2D (x, y) plane.

Fields

x: f32

Horizontal component

y: f32

Vertical component

Methods

impl Point2f

pub const ORIGIN: Point2f

Mathematical origin point on the real number plane.

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

Construct a point from the components

pub fn to_i32(self) -> Point2i

Casts the point to an integer point. Will truncate integers; if another behavior is desired it should be manually performed on the values before calling this function.

pub fn to_u32(self) -> Point2u

Casts the point to an unsigned integer point. Will truncate integers; if another behavior is desired it should be manually performed on the values before calling this function. Beware this function will not produce reasonable values if the current value is negative.

pub fn to_vector(self) -> Vector2f

pub fn rounded(self) -> Point2f

Rounds the values in the point to the nearest integer, rounding away from zero in the half-way case.

See f32::round

pub fn is_approx_eq(self, other: impl Into<Point2f>, epsilon: f32) -> bool

Determines if the components of two points are less than epsilon distance from each other. Be wary that this does not check the actual distance, but a component-wise distance check. If you desire a more precise distance check, consider subtracting one point from the other and comparing the length(_sq) of the resulting vector.
