Struct nalgebra::Iso2
[−]
[src]
pub struct Iso2<N> {
pub rotation: Rot2<N>,
pub translation: Vec2<N>,
}Two dimensional isometry.
This is the composition of a rotation followed by a translation. Isometries conserve angles and distances, hence do not allow shearing nor scaling.
Fields
rotation: Rot2<N>
The rotation applicable by this isometry.
translation: Vec2<N>
The translation applicable by this isometry.
Methods

Creates a new isometry from a rotation matrix and a vector.
fn new_with_rotmat(translation: Vec2<N>, rotation: Rot2<N>) -> Iso2<N>
