EULER ANGLESPOLAR ANGLESDIRECTION COSINESRotation is a core crystallographic operation. Two sets of Cartesian coordinates of each point of a rotated object, those before and after rotation, are linearly related, and the coefficients of these linear combinations can be represented in matrix form. This...
When converting any rotation controller to an Euler controller it is possible for sign flips to occur in the resulting animation. This is due to the fact that one single rotation matrix can be expressed through many different triplets of Euler angles. Sometimes the produced Euler angles are not...

We are especially interested in the 3D rotation group\textrm{SO}(3). Every rotation matrix can be written as the rotation around an axis{{\varvec{n}}}\in \mathbb {S}^2with an angle\omega \in \mathbb {T}{:=\mathbb {R}/(2\pi \mathbb {Z})}, i.e., ...
