Struct Line2D 

pub struct Line2D { /* private fields */ }

A 2D line defined by origin and direction.

Parameterized as P(t) = origin + t * direction.

Implementations

impl Line2D

pub fn new(origin: Point2, direction: Vec2) -> Result<Self, MathError>

Creates a new 2D line.

Errors

Returns MathError::ZeroVector if direction has zero length.

pub fn evaluate(&self, t: f64) -> Point2

Evaluates the line at parameter t.

pub const fn tangent(&self, _t: f64) -> Vec2

Returns the (constant) tangent direction.

pub fn project(&self, point: Point2) -> f64

Projects a point onto the line, returning the closest parameter.

pub fn distance_to_point(&self, point: Point2) -> f64

Returns the perpendicular distance from a point to the line.

pub const fn origin(&self) -> Point2

Returns the origin point.

pub const fn direction(&self) -> Vec2

Returns the direction vector.
