Rotation angle sequence
Posted: Thu May 19, 2022 1:46 am
Hello,
does anyone know how the sequence of the rotation angles in OpenSim is defined when appliying it on a joint center?
For better understanding: In a python script where I have imported landmarks in the 3D space, I have evaluated all three angles of a body with respect to the origin.
Therefore, I have choosen a random order alpha, beta and gamma in the three axis for the derotation. When setting them know in OpenSim I need to apply them in the reverse order to be correct as far as I know. So, there would be the question how the sequence is defined in OpenSim and how this could be changed.
Many thanks for your help
