The Lua API consists out of several modules. For linear algebra operations, we provide bindings to the C++ library, GLM, in the glm module. The window module is used to get information about and manipulate the application's window. Various values related to the keyboard and mouse, are stored in the keyboard and mouse modules. Finally, and most importantly, the scene module contains functionality for manipulating the scene as well as various objects for building a scene and displaying text on the screen. Note that if you find Lua to be too slow for some operations, you can write your own modules in C.
