This repository contains:
This repository does not include source code for the OpenSim GUI. The source code for the Opensim GUI can be found here.
Depending on your needs, there are different ways of downloading and setting up OpenSim:
OpenSim's documentation can be found in our Documentation website.
OpenSim's C++ API reference can be found here.
A simple example of an elbow simulation in C++, Python and Matlab can be found in the OpenSim API Example page of this repository's wiki.
Examples and Tutorials for OpenSim can be found in the Examples and tutorials website. These tutorials move from introductory to more advanced, so you can learn OpenSim in a progressive way. Additional OpenSim-based tutorials, homework problems, and project ideas are available on the Biomechanics of Movement classroom site.
This repository contains releases for OpenSim 4.x. You can find all of the OpenSim's releases in the Releases page of this repository.
We provide scripts to build OpenSim on Windows, macOS and Linux (Ubuntu and Debian). The instructions to download and execute the scripts can be found in the Build Instructions page of this repository's wiki.
