README

        
This repository contains (work-in-progress) sparse-implementations of 3D

Projective Geometric Algebra, intended for use in computer graphics.

There is an implementation based on rigidgeometricalgebra.org (`rga`), and

there is also an implementation largely based on PGA4CS.pdf on bivector.net

(`ega`).

---

There is basically complete test coverage, and most of the important operators

have been implemented. While `rga` is in a more "complete" state compared to

`ega` it would be possible to use either of the libraries, with the following

caveats:

- Some higher-level/compound operators (sandwich products, &c) do not yet have

  their own sparse implementations;

- there is currently no feature enabling explicit SIMD optimisations;

- some desirable 3rd party traits do not yet have implementations (bytemuck,

  serde, rand, mint);

- aside from the included unit tests, to my knowledge there has been no

  extensive use of these libraries in production code or otherwise.

Other considerations:

- While `mint` serves as a light-weight common interchange interface for

  traditional gamedev math types, it occurs to me that (projective)

  geometric-algebra libraries might be better served by their own interchange

  crate; there-by allowing `ega`, `rga`, and other geometric algebra

  implementations to co-exist.
