Graphmath is a library for handling common 2D and 3D operations, usually with an eye towards vector arithmetic for graphics and simulation.
It's designed to be comfortable to use, reasonably fast, and something which will benefit game developers and graphics programmers, though it may also be useful for robotocists and anyone attempting large-scale simluations which exist in R2 or R3.
This package is available from the hex package manager.
Just add it to your mix.exs
file like so:
def project do
[app: myapp,
version: "x.y.z",
elixir: "~> 1.0",
description: "description",
package: ...,
deps: [
...,
{:graphmath, "~> 1.0.2" },
...
] ]
end
All mathematics are done in a right-handed coordinate system--that is to say, +Z is the cross-product of +X with +Y.
All operations are accompanied by tests and documentation.

Bask in the glory of having helped create content on one of the best platforms ever devised.
C/SIMD native extensions (probably want to live in a different, API-compatible library).
Left-handed coordinate system support (don't care enough right now, but some interop would appreciate it).
Functions to convert to packed 32-bit and 64-bit float byte arrays.
