# obj2mjcf [![PyPI Python Version][pypi-versions-badge]][pypi] [![PyPI version][pypi-badge]][pypi] [pypi-versions-badge]: https://img.shields.io/pypi/pyversions/obj2mjcf [pypi-badge]: https://badge.fury.io/py/obj2mjcf.svg [pypi]: https://pypi.org/project/obj2mjcf/ `obj2mjcf` is a CLI for proccessing composite Wavefront [OBJ] files for use in [MuJoCo]. It automatically: * Splits an OBJ file into sub-meshes that are grouped by the materials referenced in the OBJ's MTL file * Generates an MJCF XML file that is pre-filled with materials, meshes and geom elements referencing these OBJ files * Optionally generates a collision mesh by performing a convex decomposition of the OBJ using [CoACD] `obj2mjcf` was used to process model meshes for [MuJoCo Menagerie]: <p float="left"> <img src="https://raw.githubusercontent.com/deepmind/mujoco_menagerie/main/anybotics_anymal_c/anymal_c.png" height="200"> <img src="https://raw.githubusercontent.com/deepmind/mujoco_menagerie/main/franka_emika_panda/panda.png" height="200"> </p> ## Motivation As of June 2022, MuJoCo does not support composite OBJ files consisting of groups or objects (`o` or `g` OBJ tags) and only 1 material can be assigned per mesh. This means that you have to manually split your OBJ file into sub-meshes, a process that is tedious and error-prone. This tool is meant to automate this process. ## Installation **Important.** MuJoCo support for OBJ files is only available in versions 2.1.2 and above. Make sure you upgrade to the latest version via the [Releases page](https://github.com/deepmind/mujoco/releases). The recommended way to install this package is via [PyPI](https://pypi.org/project/obj2mjcf/): ```bash pip install --upgrade obj2mjcf ``` ## Usage Type the following at the command line for a detailed description of available options: ```bash obj2mjcf --help ``` [OBJ]: https://en.wikipedia.org/wiki/Wavefront_.obj_file [MuJoCo]: https://github.com/deepmind/mujoco [CoACD]: https://github.com/SarahWeiii/CoACD [MuJoCo Menagerie]: https://github.com/deepmind/mujoco_menagerie
