Joints coordinates definition for a binocular model
Posted: Tue May 30, 2023 5:45 am
Dear all,
I am working on the Opensim Oculomotor Model for kinematics and dynamics simulation, and I have been trying to convert this model into a binocular model for the past few days.
My issue is with the ExpressionBasedForces I believe. Indeed, I managed to translate the origin of the model between the two eyes, and create a left eye with the same properties as the right one. Yet, my activation simulations seem wrong, due to the expression based forces. I believe that, since they use the coordinates of the joint, I don't manage to translate the referential to the new position of my eyes, in order to obtain valid expression within the eye joint reference frame.
Does anyone know how to address this issue ?
Thank you for your kind help,
Julien
