Expand description

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.

Associated Types

Required methods

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

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

Rotate a vector using this rotation.

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

Provided methods

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