manim_extensions extends Manim with:

• Chinese formula support — render Chinese characters inside MathTex via xelatex / xeCJK
• Reusable mobjects — labelled dots, braces and arrows tied to formulas, file trees, motion trails, shadows, 3D vectors, tree diagrams, and more
• Geometry helpers — circle / line / arc intersections and tangent points
• Common animations — typewriting, random / reverse writes, highlights, sweep effects, and extra easing functions
• Bundled toolkits — involute gears, mind maps / timelines / catalog diagrams, compass-and-straightedge constructions, algorithm visualisation, automata, circuits, data structures, meshes, neural networks, physics, Rubik's cube, sequence diagrams, and TikZ integration

Installation

pip install manim_extensions

Requires Manim Community Edition (>=0.21). For the Chinese-formula features you also need xelatex with the xeCJK package installed.

Optional extras

Each bundled module only pulls in what it needs. The base install is just manim + numpy; heavy or niche dependencies are lazy-imported and belong to the matching extra:

pip install manim_extensions[all]         # every module at once
pip install manim_extensions[automata]    # xmltodict
pip install manim_extensions[chemistry]   # pandas, xmltodict, requests
pip install manim_extensions[dev]         # pytest for running tests
pip install manim_extensions[docs]        # sphinx + furo for building docs
pip install manim_extensions[meshes]      # trimesh, moderngl
pip install manim_extensions[ml]          # matplotlib, scikit-learn, seaborn, tqdm
pip install manim_extensions[physics]     # pymunk, shapely
pip install manim_extensions[qr]          # segno
pip install manim_extensions[rubikscube]  # kociemba
pip install manim_extensions[svg]         # svgpathtools
pip install manim_extensions[video]       # opencv (VideoMobject)

If a feature is used without its extra installed, the error message names the exact pip install manim_extensions[...] command.

Every vendored module has a same-named extra. The ones below declare no additional dependencies (they work with the base install) but exist so that installs can uniformly request manim_extensions[<module>]: algorithm, arabic, circuit, compass, data_structures, economics, fontawesome, gearbox, mindmap, sequence_diagram, table, tikz, weighted_line.

Why we bundle upstream packages

Most of manim_extensions is vendored: source copied from small, independent upstream Manim extension projects and maintained here as one coherent, tested whole. The motivations:

• Upstream metadata locks. Some upstream packages declare dependency ranges that conflict with reality. For example manim-nerdfont-icons 1.0.x pins manim>=0.19,<0.20 on PyPI even though it works with current manim — it is bundled as manim_extensions.utils.nerdfont instead of being a dependency. manim-mobject-svg similarly declares python<3.13; it stays a lazily-imported plugin for that reason.
• Integration. Vendoring lets us normalise import style, docstring conventions and CI checks across all modules, fix cross-module bugs in one place, and keep every public name importable from a single package.
• Longevity. Several upstream projects are inactive; vendoring decouples this package from their release cadence.
• Lean installs. Because each module's extra dependencies are lazy-imported, the base install stays at two packages while every feature remains a pip install manim_extensions[...] away.

Every vendored package's upstream repository, sync version and local patches are tracked in VENDORED.md; patched files carry a # patched: <reason> marker in their header. Licensing and attribution are kept per-package in REUSE.toml.
