pub fn angular_vector(&self) -> Vector1<N>

The angular part of the velocity.

pub fn as_slice(&self) -> &[N]

This velocity seen as a slice.

The linear part is stored first.

This velocity seen as a mutable slice.

The linear part is stored first.

pub fn as_vector(&self) -> &Vector3<N>

This velocity seen as a vector.

The linear part is stored first.

pub fn as_vector_mut(&mut self) -> &mut Vector3<N>

This velocity seen as a mutable vector.

The linear part is stored first.

pub fn from_vector<S: Storage<N, U3>>(data: &Vector<N, U3, S>) -> Self

Create a velocity from a vector.

The linear part of the velocity is expected to be first inside of the input vector.

pub fn from_slice(data: &[N]) -> Self

Create a velocity from a slice.

The linear part of the velocity is expected to be first inside of the input slice.

pub fn shift(&self, shift: &Vector2<N>) -> Self

Compute the velocity of a point that is located at the coordinates shift relative to the point having self as velocity.

pub fn rotated(&self, rot: &Rotation2<N>) -> Self

Rotate each component of self by rot.

pub fn transformed(&self, iso: &Isometry2<N>) -> Self

Transform each component of self by iso.
