Description: Perl routines to handle operations on quaternions
Math::Quaternion lets you create and manipulate quaternions. A quaternion is a
mathematical object developed as a kind of generalization of complex numbers,
usually represented by an array of four real numbers, and is often used to
represent rotations in three-dimensional space.
.
See, for example, http://mathworld.wolfram.com/Quaternion.html for more
details on the mathematics of quaternions.
.
Quaternions can be added, subtracted, and scaled just like complex numbers or
vectors -- they can also be multiplied, but quaternion multiplication DOES
NOT COMMUTE. That is to say, if you have quaternions $q1 and $q2, then in
general $q1*$q2 != $q2*$q1. This is related to their use in representing
rotations, which also do not commute.
