# [−][src]Struct ncollide3d::query::Ray

A Ray.

## Fields

`origin: Point<N>`

Starting point of the ray.

`dir: Vector<N>`

Direction of the ray.

## Methods

`impl<N: Real> Ray<N>`

[src]

`impl<N: Real> Ray<N>`

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

[src]

`pub fn new(origin: Point<N>, dir: Vector<N>) -> 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>) -> Self`

[src]

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

Transforms this ray by the given isometry.

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

[src]

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

Transforms this ray by the inverse of the given isometry.

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

[src]

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

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

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

[src]

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

Computes the point at the given parameter on this line.

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

.
