jit.gl.lua integrates Lua scripting with Jitter OpenGL processing. jit.gl.lua has full access to Jitter 3D functionality, including low-level utility functions. There are also built-in bindings to nearly all of the low-level OpenGL functions for direct scripting of OpenGL within Jitter. The functionality of jit.gl.lua can be extended with the Lua module system, so other libraries such as physics simulators, OpenGL gui toolkits, etc. can easily be accessed.
