[![Coverage Status](https://coveralls.io/repos/github/excessive/cpml/badge.svg?branch=master)](https://coveralls.io/github/excessive/cpml?branch=master)

Various useful bits of game math. 3D line intersections, ray casting, 2d/3d vectors, 4x4 matrices, quaternions, etc.

Intended to be used with LuaJIT and LÖVE (this is the backbone of LÖVE3D).

Online documentation can be found [here](http://excessive.github.io/cpml/) or you can generate them yourself using `ldoc -c doc/config.ld -o index .`

# Installation

Clone the repository and require it, or if you prefer luarocks: `$ luarocks install --server=http://luarocks.org/dev cpml`. Add `--tree=whatever` for a local install.

# Versions

This library has a major compatibility break at version 1.0. Up to version 0.10, composition `a*b` means "apply b, then a" for quaternions and "apply a, then b" for matrices. Now as of version 1.0, the two are consistent and matrix `a*b` means "apply b, then a".
