smallvectors is a lightweight library that implements linear algebra operations in low dimensions. These objects were create to be used in a game engine, but may be useful elsewhere.

The library has an opt-in process for optimizing code with C-extensions written in Cython. The optimized version of the library is (or will be) one of the fastest Python packages for low dimensional linear algebra operations.

Small vectors supports:

• Vector, point and direction types
• Arbitrary matrices and some specialized ones (square matrices, unitary matrices, rotational matrices, etc).
• Affine transforms
• Quaternions
