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 Methods

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

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

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

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
