Converting a rotation matrix to Euler angles is a bit tricky. The solution is not unique in most cases. Using the code in the previous section you can verify that rotation matrices corresponding to Euler angles ( or in degrees) and ( or in degrees) are actually the same even though the ...

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.

A coordinate system matrix (similar to a segment definition) is then defined and denoted the ‘Progression Frame’. This allows the calculation by Plug-in Gait and Polygon of ‘progression’ related variables (HeadAngles, ThoraxAngles, PelvisAngles, FootProgressAngles, Step Width) in relation to ...
