# [−][src]Struct nphysics2d::algebra::Velocity2

A velocity structure combining both the linear angular velocities of a point.

## Fields

`linear: Vector2<N>`

The linear velocity.

`angular: N`

The angular velocity.

## Methods

`impl<N: RealField> Velocity2<N>`

[src]

`pub fn new(linear: Vector2<N>, angular: N) -> Self`

[src]

Create velocity from its linear and angular parts.

`pub fn new_with_vectors(linear: Vector2<N>, angular: Vector1<N>) -> Self`

[src]

Create velocity from its linear and angular parts.

`pub fn angular(w: N) -> Self`

[src]

Create a purely angular velocity.

`pub fn linear(vx: N, vy: N) -> Self`

[src]

Create a purely linear velocity.

`pub fn zero() -> Self`

[src]

Create a zero velocity.

`pub fn between_positions(`

start: &Isometry2<N>,

end: &Isometry2<N>,

time: N

) -> Self

[src]

start: &Isometry2<N>,

end: &Isometry2<N>,

time: N

) -> Self

Computes the velocity required to move from `start`

to `end`

in the given `time`

.

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

[src]

The angular part of the velocity.

`pub fn integrate(&self, dt: N) -> Isometry2<N>`

[src]

Compute the displacement due to this velocity integrated during the time `dt`

.

`pub fn to_transform(&self) -> Isometry2<N>`

[src]

Compute the displacement due to this velocity integrated during a time equal to `1.0`

.

This is equivalent to `self.integrate(1.0)`

.

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

[src]

This velocity seen as a slice.

The linear part is stored first.

`pub fn as_mut_slice(&mut self) -> &mut [N]`

[src]

This velocity seen as a mutable slice.

The linear part is stored first.

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

[src]

This velocity seen as a vector.

The linear part is stored first.

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

[src]

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`

[src]

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`

[src]

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`

[src]

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`

[src]

Rotate each component of `self`

by `rot`

.

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

[src]

Transform each component of `self`

by `iso`

.
