Detailed Description

quaterniond - the rotation around the vector

Quaternions are used in the system of Hypercomplex numbers, form a vector space of dimension four over the field of real numbers. Vector quaternions form a three-dimensional real vector space, which can be used to describe any rotation of this space as the object is rotated around the center of the starting position in the final, at the expense derived from the rotation of the fixed points lying on the straight line and the angle of rotation around it.
