[SciPy-Dev] GSoC 2018 : Rotation formalism

[Divyank Agarwal]

Quaternions as a number system is good idea for 3d rotation.
It takes away Edge cases issues with Euler angles, like gimbal lock.

Quaternions are 4D counterpart of complex numbers.
However their non commutativity makes them a challenge to understand and
visualize,
making mathematics bit complicated.



A specific quaternion library already exist on github.
https://github.com/moble/quaternion
"This Python module adds a quaternion dtype to NumPy."

Advanced functionalities could be added above the library.



Their are good use cases of Quaternions.
If your smartPhone has orientation sensors, It probably uses Quaternions.
