"""This package creates a quaternion type in python, and further enables
|
|
numpy to create and manipulate arrays of quaternions. The usual algebraic
|
|
operations (addition and multiplication) are available, along with numerous
|
|
properties like norm and various types of distance measures between two
|
|
quaternions. There are also additional functions like "squad" and "slerp"
|
|
interpolation, and conversions to and from axis-angle, matrix, and
|
|
Euler-angle representations of rotations. The core of the code is written in
|
|
C for speed."""
