Struct makepad_vector::geometry::Vector

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

A vector 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: f64

y: f64

Implementations

impl Vector

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

Creates a new vector with the given coordinates.

pub fn zero() -> Vector

Returns the zero vector.

pub fn to_point(self) -> Point

Converts self to a point.

This is equivalent to adding self to the origin.

pub fn length(self) -> f64

Returns the length of self.

pub fn normalize(self) -> Option<Vector>

Returns the unit vector in the direction of self, or None if self is the zero vector.

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

Returns the dot product of self and other.

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

Returns the cross product of self and other.

pub fn scale(self, v: Vector) -> Vector

Non-uniformly scales self with the scale vector v.
