For best memory performance: have luaJIT & it's FFI library (this should be built into luaJIT), and add MTUL-CPML 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.
