Finally normalizing the rotation axis : When building the global pose of a skeleton from its local pose, as discussed in this blog post. To use a quaternion you have to convert it into a 3x3 rotation matrix.

Instead Of A, B, C, And D, You Will Commonly See:


Determine the product of two quaternions. Q 1, q 2, and q 3 correspond to an axis of rotation about which the angle of rotation is performed.; Multiplying a matrix with a pure quaternion.

Q = A +B.i +C.j + D.k R = E +F.i +G.j + H.k Where The Coefficients A Through H Are Real, The Product Is Given By The Rules:


The conjugate of a quaternion, analogous to the conjugate of a complex number, is ˙q∗ = q 0 −iq x −jq y −kq z. Here the matrix elements of the factors are quaternions, which don’t commute, so the diagonal elements ac − bd * and a * c * − b * d are not conjugates of one. Quaternion multiplication and orthogonal matrix multiplication can both be used to represent rotation, this page aims to show that these two notations are equivalent.

In Each Case, The Representation Given Is One Of A Family Of Linearly Related Representations.


The rotated quaternion p' = q p q −1 needs to be differentiated with respect to the rotating quaternion q, when the rotation is estimated from numerical optimization.the estimation of rotation angle is an essential procedure in 3d object registration or camera calibration. Just as complex numbers can be represented as matrices, so can quaternions. Consider the octonion multiplication, whose factors represented as matrices analogous to the quaternion case above.

Quaternion Multiplication Is Defined As Equation 2.24.


For example, to apply a p quaternion followed by a q quaternion, multiply in the order pq. It is not difficult to verify that multiplication of quaternions is distributive over addition. If the “*” operator is used in vector, matrix or quaternion multiplication in blender 2.8 it throws an error:

Here's A Little Example Using Your Function:


In the terminology of abstract algebra, these are inj… This page discusses the equivalence of quaternion multiplication and orthogonal matrix multiplication. In blender 2.7 the “*” (star) operator is used in the matrix, vector, and quaternion multiplication.
