TanGA
Geometric algebra library with a C++ core and a Python interface (pytanga).
→ Full documentation — C++ and Python API guides, architecture overview, notebooks, and developer workflows.
Key Features
-
High-dimensional algebras — Sparse blade encoding for vector spaces up to 31 dimensions with arbitrary signature. Storage proportional to non-zero coefficients, not the full $2^D$ blade space.
-
C++ template header library — 100 % C++17 headers with
constexpr-friendly templates. Compile-time dimension and signature let the compiler inline blade arithmetic down to machine instructions. -
On‑demand Python compilation — pytanga generates, compiles, and caches pybind11 bindings on first use. Pre‑compiled wheels for common configurations ship with the package — zero-setup
pip installfor most users. -
GA formula solving — Convert product equations into linear systems, solve with Gaussian elimination (floating-point or modular), and reconstruct the unknown multivector.
-
Matrix and tensor pipelines — Blade-mask-aware matrices and labeled tensors with Einsum-style contractions, broadcasts, and slicing on multivector data.
-
Geometry analysis and creation —
analyze()extracts geometric meaning from a multivector;create()builds one from primitives. Works across E3, P3, N3, and PGA3 algebras. -
Interactive 3D visualization — Live WebSocket-driven Three.js visualizer in the browser. Export to standalone HTML, glTF/GLB, PNG, or MP4.
Installation
pip install tanga-py
No C++ compiler or build tools required. pytanga ships with precompiled bindings for the five most common algebra configurations on Linux (x86_64) and Windows (win_amd64).
If you need a custom algebra not covered by the precompiled set, add the
compile extra (pip install "tanga-py[compile]") — see the
installation guide
for per-platform compiler setup instructions.
AI Tool Documentation Access
When pytanga is installed, the markdown documentation is packaged inside the
wheel. AI coding tools can expose it by calling pytanga.install_docs(), which
creates a symlink at .dep-docs/pytanga/ in the current repository root.
