Struct rg3d_core::math::Rect

pub struct Rect<T: Scalar> {
    pub position: Vector2<T>,
    pub size: Vector2<T>,
}

Fields

position: Vector2<T>

size: Vector2<T>

Implementations

impl<T> Rect<T> where
    T: Scalar + Add<Output = T> + Sub<Output = T> + Mul<Output = T> + PartialOrd + Copy + AddAssign, 

pub fn new(x: T, y: T, w: T, h: T) -> Self

#[must_use = "this method creates new instance of rect"]

pub fn inflate(&self, dw: T, dh: T) -> Self

#[must_use = "this method creates new instance of rect"]

pub fn deflate(&self, dw: T, dh: T) -> Self

pub fn contains(&self, pt: Vector2<T>) -> bool

pub fn push(&mut self, p: Vector2<T>)

Extends rect to contain given point.

Notes

To build bounding rectangle you should correctly initialize initial rectangle:

let vertices = [Vector2::new(1.0, 2.0), Vector2::new(-3.0, 5.0)];

// This is important part, it must have "invalid" state to correctly
// calculate bounding rect. Rect::default will give invalid result!
let mut bounding_rect = Rect::new(f32::MAX, f32::MAX, 0.0, 0.0);

for &v in &vertices {
    bounding_rect.push(v);
}
