NOTE: This repository contains the source code of OpenSim Java GUI 4.x and cannot be used to build OpenSim 3.x or earlier.
OpenSim is software that lets users develop models of musculoskeletal structures and create dynamic simulations of movement.
More information can be found at our websites:
- OpenSim website, in particular the support page.
- SimTK project website.
This repository does not include source code for the OpenSim core API. The source code for the OpenSim core API can be found here.
You can download OpenSim GUI from the simtk website:
- OpenSim GUI
- Looking for help?
OpenSim's documentation can be found in our Documentation website.
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 GUI 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.
Due to the small development team working on the GUI, we do not provide support for building or altering the OpenSim GUI source code. The provided build instructions may get out of date occasionally. The defacto instructions are those included/used by the Continuous Integration (CI) build scripts. See the OpenSim Confluence Wiki for additional information.
There are many ways in which you can participate in this project. For example:
- Report bugs and request features by submitting a GitHub Issue.
- Ask and answer questions on our Forum.
- Review and test new Pull Requests.
- Review the Documentation and the Wiki by reporting typos, confusing explanations and adding/suggesting new content.
- Fix bugs and contribute to OpenSim GUI's source code by creating a Pull Requests.
