Overview

OpenSim Creator (osc) is a standalone UI for building and editing
OpenSim models. It's available
as a freestanding all-in-one installer for Windows 10 (>= 1507),
MacOS (>= 14.5, Sonoma), and Ubuntu (>= 22.04, Jammy Jellyfish).
osc started development in 2021 in the Biomechanical Engineering
department at TU Delft. Architecturally, osc is a C++ codebase
that is directly integrated against the OpenSim core C++ API. It
otherwise only uses lightweight open-source libraries that can easily be built from source
(e.g. SDL) to implement the UI on all target platforms. This makes osc
fairly easy to build, integrate, and package.
Citing/Acknowledging
OpenSim Creator doesn't have a central written software publication that you can cite (yet ). However, if you need to directly cite OpenSim Creator (e.g. because you think it's relevant that you built a model with it), the closest thing you can use is our DOI-ed Zenodo releases (metadata available in this repo: CITATION.cff/codemeta.json):
Kewley, A., Beesel, J., & Seth, A. (2025). OpenSim Creator (0.5.25). Zenodo. https://doi.org/10.5281/zenodo.15882091
If you need a general citation for the simulation/modelling technique, you can directly cite OpenSim via this paper:
Seth A, Hicks JL, Uchida TK, Habib A, Dembia CL, et al. (2018) OpenSim: Simulating musculoskeletal dynamics and neuromuscular control to study human and animal movement. PLOS Computational Biology 14(7): e1006223. https://doi.org/10.1371/journal.pcbi.1006223
Sustainability, Archiving, and Mirrors
We have taken the following steps to ensure that you can always access, build, and use every release of OpenSim Creator:
- OSC's central repository is public access and hosted at https://github.com/ComputationalBiomechanicsLab/opensim-creator
- During a release, we:
- Mirror the central repository to https://gitlab.tudelft.nl/computationalbiomechanicslab/opensim-creator
- Upload a snapshot of the release's source code to Zenodo (see citing section, above).
- Upload a snapshot of the release's source code and binaries to https://files.opensimcreator.com/releases/
- Each release of OSC's source code is permissively licensed, verified to be compile-able via
gcc,clang, and MSVC with many warnings/lints enabled to ensure the source code has a strong chance of being compile-able far in the future as architectures, operating systems, and compilers evolve. - The project includes all of its library dependencies in-tree. It doesn't use git submodules, internet downloads, or package managers. This means that everything that's needed to build OpenSimCreator (apart from widely-available compiler toolchains) is available in this repository and not dependent on external services that might change over time.
Contributing
If you would like to contribute to OpenSim Creator then thank you : it's people like you that make open-source awesome! Please consult the contribution section in the official documentation. The development section of the documentation also outlines how to build the project from source!
Acknowledgements
We would like to thank the Chan Zuckerberg Initiative which currently funds OpenSim Creator's development through the "Essential Open Source Software for Science" grant scheme (Chan Zuckerberg Initiative DAF, 2020-218896 (5022)).
We would also like to thank the Department of Biomechanical Engineering at TU Delft, which has provided the necessary institutional support required to keep OpenSim Creator's development supported and stable.
