I would like to be able to visualize non-orthogonal joint axes of rotation in the GUI.
For example, in the MoBL-ARMS Dynamic Upper Limb model, the wrist's radiocarpal joint has two non-orthogonal axes of rotation described in rotation1 [-0.819064 -0.135611 -0.557444] and rotation3 [0.95642673 -0.25220693 0.14710396]. My understanding is that the parent/child frame description on the joint does not allow visualization of both of these axes simultaneously because any input for the orientation_in_parent will transform (and display) the orthogonal coordinate system of the bone. |
