manim

Manim Community (ManimCE) is a community-maintained Python framework for producing explanatory mathematical animations programmatically. It is a fork of the original 3b1b/manim project created by Grant Sanderson, and the README recommends this edition for its continued development, improved features, enhanced documentation, and active community maintenance. Key capabilities evidenced in the README: - Scene-based animation API: users define Python classes subclassing Scene and implement a construct method, composing geometric objects such as Circle and Square and animation calls like Create, Transform, and FadeOut. - Command-line interface: scenes are rendered with commands such as `manim -p -ql example.py SquareToCircle`. Flags include -p for previewing the rendered video, -ql for faster lower-quality rendering, -s to show only the final frame, -n to skip to the n-th animation, and -f to reveal the file in a file browser. - Jupyter integration: a `%%manim` IPython magic allows rendering inside JupyterLab and classic Jupyter notebooks, with an online Binder example available. - Distribution: installable from PyPI and available as a Docker image (manimcommunity/manim) on DockerHub, with installation instructions per operating system in the documentation. - Documentation and examples: hosted on ReadTheDocs, including an official example gallery, configuration guide, and contributing guide. - Community support: Discord server and Reddit community for help, plus issue tracking for bug reports and feature requests. - Development workflow: contributors commonly use uv for environment management, with a dedicated development installation guide. - Licensing: dual-licensed under the MIT license, with copyright held by 3blue1brown LLC and by Manim Community Developers. The README notes that the project is undergoing a major refactor and that new-feature contributions are generally not being accepted during this period. It also cautions that installation instructions differ between this community edition and the original 3b1b/manim repository, and that mixing them causes problems.
