lua-cqr

Extended idiomatic Lua interface to the CQRlib quaternion library.

This module provides an extended idiomatic Lua interface to the CQRlib library written by Herbert J. Bernstein. It is not a "binding" and access to the original documentation is only required for those who wish to understand the module's C code in cqr.c.

A quaternion is implemented as an immutable userdata consisting of four double precision numbers. The metatable of that module, which is its own __index, is returned by require "cqr".

Full documentation is provided in lua-cqr.html.
