Thanks, I'll take a look. Unfortunately I'm not very well-versed in C++ which is why I'm working in MATLAB to begin with. At some point I'll bite the bullet and convert the code to C++...

Chris - Bringing this thread back to life. I've played around with some of you suggestions, and am still running into issues visualizing everything correctly. I have a MATLAB demo zipped up and posted here if you have a chance to take a look, although it requires you have the 4.0 MATLAB API set up: ...

Thanks so much for response, I will play around with some of your ideas and let you know how it goes. To answer some of your questions, I was planning on using the global frame for each state, just because that is how I am used to operating in Unity. Also, I'm using MATLAB right now as I'm more comf...

Thanks for the responses! What I'm trying to do is visualize the OpenSim model in Unity, which I'll eventually use to build a Hololens app. My thought process was that I could convert all geometries attached to each body from .vtp to .blend which is accepted by unity, then use the getTranformInGroun...

They are methods for the body class but are new to the 4.0 AP I. Actually it is getTranformInGround instead of getRotationInGround, was going from memory.

Hi all, Just wanted to clarify, when working with the 4.0 API, do these methods return the translations and rotations of the geometry file with respect to the CAD space of the VTP file? As for the rotation, what is the origin, (0,0,0)? Otherwise, if the origin based on the geometric center of the ge...

This worked, thank you very much.

Worked like a charm, thanks Tom.

Hi all, I'm working on post-processing some simulation results in MATLAB, and I need to load in some previously run simulations. Right now my workflow is to load and initialize the .osim model, then read in the .mot file using a generic MATLAB parse command, loop through and update model coordinates...

Hello, I am working on some MATLAB code which uses the OpenSim 4.0 API to read in an existing model, but I can't figure out how to get the visible object files associated with each body. Right now I have: % Import opensim classes import org.opensim.modeling.* % Read in model from file model_file = '...
