euclid3

What it is and what it does

euclid3 is a pure-Python mathematics library for 2D and 3D geometric operations. It provides vector, matrix, quaternion, and basic geometry primitives, originally written for Python 2 and updated for Python 3 in 2014. The library is abandoned—no releases or updates since 2014-05-14—and carries no specified Python version support, making its compatibility with modern Python versions uncertain.

The package has no runtime dependencies and installs with high friction due to its age and lack of maintenance signals. It is positioned as a lightweight alternative for small-scale geometric calculations, though its long dormancy means it has not benefited from bug fixes, performance improvements, or compatibility updates that modern libraries have received.

Use it for:

• Lightweight 2D/3D vector and matrix math in legacy Python projects that cannot migrate to modern libraries.
• Quaternion operations for rotation calculations in graphics or physics simulations in older codebases.
• Educational purposes to understand basic Euclidean geometry and linear algebra concepts in Python.
• Prototyping geometric algorithms when other libraries are unavailable or unsuitable for the task.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides 2D and 3D vector, matrix, quaternion, and geometry math operations for Python, updated for Python 3 compatibility.

No. The package is abandoned (no updates since 2014-05-14), has unclear license metadata, no specified Python version support, and high install friction. Modern alternatives are actively maintained, better documented, and more reliable. Install only if you are maintaining legacy code that already depends on it.

Install

Installing euclid3

Before you install

High install friction: the package is abandoned (last release 2014-05-14, no activity for 4475 days) with no specified Python version support. The distribution format suggests potential compatibility issues with modern Python tooling.

License in practice

License treatment is unclear—the raw metadata shows 'UNKNOWN' with no SPDX identifier, though the description excerpt indicates LGPL 2.1. Verify the actual license terms before use in proprietary or copyleft-sensitive projects.

Quickstart

pip install euclid3
import euclid3
v = euclid3.Vector3(1, 2, 3)
print(v.magnitude())

No Python version specified; compatibility with modern Python versions is unverified. The package has not been maintained since 2014-05-14.

Verify before relying

• Whether euclid3 actually works on current Python versions despite the 2014 release date.
• Whether the LGPL 2.1 license stated in the description is the authoritative license or if 'UNKNOWN' metadata indicates a licensing issue.
• Performance characteristics and numerical stability compared to alternatives.
