Struct Line3D 

pub struct Line3D { /* private fields */ }

A 3D line defined by origin and direction.

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

Implementations

impl Line3D

pub fn new(origin: Point3, direction: Vec3) -> Result<Self, MathError>

Create a new line.

Errors

Returns an error if direction is zero-length.

pub fn evaluate(&self, t: f64) -> Point3

Evaluate the line at parameter t.

pub const fn tangent(&self) -> Vec3

The tangent direction (constant for a line).

pub fn project(&self, point: Point3) -> f64

Project a point onto the line, returning the parameter.

pub fn distance_to_point(&self, point: Point3) -> f64

Distance from a point to the line.

pub const fn origin(&self) -> Point3

The line origin.

pub const fn direction(&self) -> Vec3

The unit direction.
