Struct rin::scene::physics::Ray

pub struct Ray<N> where
    N: RealField,  {
    pub origin: Point<N, U3>,
    pub dir: Matrix<N, U3, U1, <DefaultAllocator as Allocator<N, U3, U1>>::Buffer>,
}

A Ray.

Fields

origin: Point<N, U3>

Starting point of the ray.

dir: Matrix<N, U3, U1, <DefaultAllocator as Allocator<N, U3, U1>>::Buffer>

Direction of the ray.

Implementations

impl<N> Ray<N> where
    N: RealField, 

pub fn new(
    origin: Point<N, U3>,
    dir: Matrix<N, U3, U1, <DefaultAllocator as Allocator<N, U3, U1>>::Buffer>
) -> Ray<N>

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

pub fn transform_by(&self, m: &Isometry<N, U3, Unit<Quaternion<N>>>) -> Ray<N>

Transforms this ray by the given isometry.

pub fn inverse_transform_by(
    &self,
    m: &Isometry<N, U3, Unit<Quaternion<N>>>
) -> Ray<N>

Transforms this ray by the inverse of the given isometry.

pub fn translate_by(
    &self,
    v: Matrix<N, U3, U1, <DefaultAllocator as Allocator<N, U3, U1>>::Buffer>
) -> Ray<N>

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

pub fn point_at(&self, t: N) -> Point<N, U3>

Computes the point at the given parameter on this line.

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

Trait Implementations

impl<N> Clone for Ray<N> where
    N: Clone + RealField, 

pub fn clone(&self) -> Ray<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N> Debug for Ray<N> where
    N: Debug + RealField, 

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<N> Copy for Ray<N> where
    N: Copy + RealField,
