[−][src]Struct nphysics2d::algebra::Inertia2
The inertia of a rigid body grouping both its mass and its angular inertia.
Fields
linear: N
The linear part (mass) of the inertia.
angular: N
The angular inertia.
Methods
impl<N: RealField> Inertia2<N>
[src]
pub fn new(linear: N, angular: N) -> Self
[src]
Creates an inertia from its linear and angular components.
pub fn new_with_angular_matrix(linear: N, angular: Matrix1<N>) -> Self
[src]
Creates an inertia from its linear and angular components.
pub fn mass(&self) -> N
[src]
Get the mass.
pub fn zero() -> Self
[src]
Create a zero inertia.
pub fn angular_matrix(&self) -> &Matrix1<N>
[src]
Get the angular inertia tensor.
pub fn to_matrix(&self) -> Matrix3<N>
[src]
Convert the inertia into a matrix where the mass is represented as a 2x2 diagonal matrix on the upper-left corner, and the angular part as a 1x1 matrix on the lower-rigth corner.
pub fn transformed(&self, _: &Isometry2<N>) -> Self
[src]
Compute the inertia on the given coordinate frame.
pub fn inverse(&self) -> Self
[src]
Inverts this inetia matrix.
Sets the angular part to zero if it is not invertible.
