Adapted for Luanti

For best memory performance: have luaJIT & it's FFI library (this should be built into luaJIT), and add LEEF-Math to your trusted list (so it can require() call the FFI library).

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

This is a fork of CPML (for LÖVE/love3d), it's been ported over the minetest so it can be used in whatever you need it for. Documentation can be found here.

For possible future contributors: documentation must be generated manually when a commit is made, because I haven't set up workflows (and have no idea how to).

TODO:

make leef.math.vec3 compatible with core.vector
make memory better memory allocation options for vec3s
improve intersect module runtime memory allocations
finish intersect module documentation
fix documentation errors in color and mat4
