Various useful bits of game math. 3D line intersections, ray casting, vectors, 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 .`

# 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".
