Great! Thank you for your reply!

Kind regards,

Hi, I am trying to evaluate the sensitivity of the kinematics to error in the modeling of the vertebral alignment. Therefore I would like to check if the following reasoning is correct: In reference to the figure below, if I would be able to move body B without changing the absolute position or orie...

We have concluded that two the reviewer was confused by an ambiguous term in our manuscript: "Total angle", which would have been correcter as "individually summed angles".


Thank you all for your help.

Hi Chris! Thanks for taking a look! If the coefficients of the linear function would have been set as shown in tabel A1.4. A , then I indeed would have had to set the only remaining independent degrees of freedom to 30, 20, 10 degrees. However, I expressed the dependent coordinates relative to this ...

Dear Ton, Thank your for taking the time to look at my issue! Although I agree with the math behind the addition of Euler angles, I believe that this is not the way OpenSim is doing the rotations when joint constraints are applied. As you suggested I applied larger angles (almost the maximum of the ...

Hi, I am hoping to get some help on a question regarding the way joint constraints are being used in relation to Euler angles. I have a thoracolumbar spine model in which the intervertebral (IV) joints are modeled as ball-and-socket joints (3 rotational degrees of freedom, no translations, red spher...

Dear Ayman, Thank you! This worked very well! I used the following line to transform my assembly relative to the world reference system: transform = _osimModel.getSimbodyEngine().getTransform(si, bodyTemp); assembly.SetUserTransform(ConvertTransformFromSim2VTK(transform)); However, when I afterwards...

Dear Ayman, Thank you for your reply. This is indeed the kind of method I am looking for. I am using the API from OpenSim 3.3. Could you point me to the method I need use, in the doxygen? (Because there exist a lot of methods such as Transform, TransformAxis, TransformPosition,...) Or maybe even wri...

Hi, I am working on some research software to make image-based personalizations to a generic musculoskeletal model. As you can see in the attachment, I have already created a pilot version in which I reconstruct this generic model in a VTK render window. Thereafter, I can manually adjust the positio...

This works!
Thank you!
