Detailed Description

A blender::math::AxisAngle<T> represents a rotation around a unit axis.

It is mainly useful for rotating a point around a given axis or quickly getting the rotation between 2 vectors. It is cheaper to create than a #Quaternion or a matrix rotation.

If the rotation axis is one of the basis axes (eg: {1,0,0}), then most operations are reduced to 2D operations and are thus faster.

Interpolation isn't possible between two blender::math::AxisAngle<T>; they must be converted to other rotation types for that. Converting to blender::math::QuaternionBase<T> is the fastest and more correct option.
