}

A trait for a generic rotation. A rotation is a transformation that creates a circular motion, and preserves at least one point in the space.

Required Associated Types

type Space: EuclideanSpace

Required Methods

fn look_at(
    dir: <Self::Space as EuclideanSpace>::Diff,
    up: <Self::Space as EuclideanSpace>::Diff
) -> Self

Create a rotation to a given direction with an ‘up’ vector.

fn between_vectors(
    a: <Self::Space as EuclideanSpace>::Diff,
    b: <Self::Space as EuclideanSpace>::Diff
) -> Self

Create a shortest rotation to transform vector ‘a’ into ‘b’. Both given vectors are assumed to have unit length.

fn rotate_vector(
    &self,
    vec: <Self::Space as EuclideanSpace>::Diff
) -> <Self::Space as EuclideanSpace>::Diff

Rotate a vector using this rotation.

fn invert(&self) -> Self

Create a new rotation which “un-does” this rotation. That is, r * r.invert() is the identity.

Provided Methods

fn rotate_point(&self, point: Self::Space) -> Self::Space

Rotate a point using this rotation, by converting it to its representation as a vector.
