WebNov 8, 2010 · Introduction. Instead of matrices, quaternions are often used to represent the orientation of three-dimensional entities in games and simulations. Quaternions require only 4 floats as opposed to the 9 floats required by a 3x3 matrix. Quaternion multiplication also requires only 16 multiplications and 12 additions versus the 27 multiplications ...
