This is in reference to #11 I used the reference numpy code and changed it to work with your library

Enhancement for converting to yaw-pitch-roll

2

Hi, I saw that this library offers the function `yaw_pitch_roll` to get the Euler angles from a quaternion. However I see they are calculated based on a fixed application of...

There appears to be an error in the section about quaternion chaining in [Basic Usage](http://kieranwynn.github.io/pyquaternion/#basic-usage). Either pyQuaternion does not follow standard quaternion multiplication conventions (I don't think so) or the...

Quaternion.distance seems to produce incorrect result

3

I'm evaluating the angular distance between two quaternions and it seems that values produced by `Quaternion.distance` are twice less in comparison with this formula: The UTs checking angular distance for...

What to do when matrix is not quite within orthogonality tolerance

2

Hi, Thanks for writing this library. I use it all the time and love its simplicity for 3D representations. I have lately been dealing with an issue pretty commonly where...

To enable deterministic sampling of orientations it is necessary to pass a seeded rng to the function. This is important for example in machine learning, when orientations need to be...

Optimise slerp() and intermediates(), make other parts more concise

1

The optimisation of `slerp()` (four fewer allocations, no inversion of one input quaternion necessary) is based on my independent derivation for my 3D engine [here](https://github.com/DroneBetter/Perspective3Dengine/blob/24b5dc4f49c8160265b4c3e479587c9703e5f6ad/perspective%203D%20engine.py#L186) `intermediates()` needs only for the...
