Struct Ray 

pub struct Ray<T, V>
where
    T: Scalar,
    V: Vector<T>,
{
    pub start: V,
    pub direction: V,
    /* private fields */
}

A ray with an origin and direction.

Commonly used for ray casting and intersection tests.

Fields

start: V

Ray origin.

direction: V

Ray direction (typically normalized).

Implementations

impl<T, V> Ray<T, V>

where T: FloatScalar, V: FloatVector<T>,

pub fn new(start: &V, direction: &V, epsilon: T) -> Option<Ray<T, V>>

Creates a new ray with normalized direction.

Returns None if the direction is too small.

impl<T> Ray<T, Vector3<T>>

where T: Scalar,

pub fn intersect_plane(&self, p: &Plane<T>, epsilon: T) -> Option<Vector3<T>>

Computes ray-plane intersection.

Returns the intersection point, or None if the ray doesn’t hit the plane (parallel or pointing away).

Returns None if the ray is parallel to the plane within epsilon.

Trait Implementations

impl<T, V> Clone for Ray<T, V>

where T: Clone + Scalar, V: Clone + Vector<T>,

fn clone(&self) -> Ray<T, V>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T, V> Default for Ray<T, V>

where T: Default + Scalar, V: Default + Vector<T>,

fn default() -> Ray<T, V>

Returns the “default value” for a type.

impl<T> Intersect<Ray<T, Vector3<T>>> for Box3<T>

where T: FloatScalar,

Intersect Queries

fn intersect(&self, other: &Ray<T, Vector3<T>>) -> bool

Returns true when two objects intersect.

impl<T> Intersection<(T, Vector3<T>), Tri3<T>> for Ray<T, Vector3<T>>

where T: FloatScalar,
