WebJun 24, 2024 · The rule contradicts the plain facts of quaternions, so it must not be a correct rule to apply to quaternions. To put it another way: put two six-sided dice on the table in front of you, oriented the same way. Rotate one a quarter turn around the x -axis and then a quarter turn around the y -axis. WebBasically the idea is this: every rotation in 3-space is specified by an axis of rotation and the angle you rotate about that axis. To find your customized u, you first compute a unit quaternion h which is normal to the plane of rotation, and then an expression like u = cos ( θ / 2) + h sin ( θ / 2) turns out to be what you want.

Just interpolating rotation matrices doesn't work, because you won't always get a rotation matrix as result. WebMay 5, 2016 · As a side note of "adding quaternions": quaternions are actually points on a 3-dimensional manifold (unit Hamiltonian hypersphere or whatever it is called). When points on a space that is not Euclidean (i.e. flat) are added, the result is no longer a point in the space of their origin.. unless the points are really close together and adding ... chris carmack just my luck
