Struct makepad_geometry::Point

pub struct Point {
    pub x: f32,
    pub y: f32,
}

A point in 2-dimensional Euclidian space.

A point represents a position, whereas a vector represents a displacement. That is, the result of subtracting two points is a vector. Moreover, the result of adding/subtracting a vector to/from a point is another point. However, adding two points is not defined. Similarly, whereas a point can be scaled, rotated, and translated, a vector can only be scaled and rotated.

Fields

x: f32

y: f32

Methods

impl Point

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

Creates a new point with the given coordinates.

pub fn origin() -> Point

Returns the point at the origin.

pub fn to_vector(self) -> Vector

Converts self to a vector.

This is equivalent to subtracting self from the origin.

pub fn lerp(self, other: Point, t: f32) -> Point

Linearly interpolate between self and other with parameter t.
