The quaternion represents a vector used to encode three-dimensional physical rotations. It is used to efficiently rotate an object about the (x,y,z) vector by angle theta, where:

w = cos(theta/2)


W - The rotation component of the quaternion.
X - The X value of the vector component of the quaternion.
Y - The Y value of the vector component of the quaternion.
Z - The Z value of the vector component of the quaternion.

Description of the functions


Returns the conjugate of a specified quaternion.


Returns the inverse of a quaternion.


Divides each component of a specified quaternion by its length.
This gives a new quaternion with length 1.


Reverses the sign of each component of the vector.
