Struct parry2d::query::Ray

pub struct Ray {
    pub origin: Point<Real>,
    pub dir: Vector<Real>,
}

A Ray.

Fields

origin: Point<Real>

Starting point of the ray.

dir: Vector<Real>

Direction of the ray.

Implementations

impl Ray

pub fn new(origin: Point<Real>, dir: Vector<Real>) -> Ray

Creates a new ray starting from origin and with the direction dir. dir must be normalized.

pub fn transform_by(&self, m: &Isometry<Real>) -> Self

Transforms this ray by the given isometry.

pub fn inverse_transform_by(&self, m: &Isometry<Real>) -> Self

Transforms this ray by the inverse of the given isometry.

pub fn translate_by(&self, v: Vector<Real>) -> Self

Translates this ray by the given vector. Its direction is left unchanged.

pub fn point_at(&self, t: Real) -> Point<Real>

Computes the point at the given parameter on this line.

This computes self.origin + self.dir * t.
