Straight-forward LuaJIT FFI bindings for OpenGL
For usage in a purely LuaJIT environment:
local gl = require("libs/gl") ("libGL.so")
...
gl.Begin(gl.GL_TRIANGLES)
gl.Color3f(1., 0., 0.)
gl.Vertex3f(-0.6, -0.4, 0.)
gl.Color3f(0., 1., 0.)
gl.Vertex3f(0.6, -0.4, 0.)
gl.Color3f(0., 0., 1.)
gl.Vertex3f(0., 0.6, 0.)
gl.End()
...However, if you intend to run your script from an embedded LuaJIT environment which has OpenGL already linked, you can omit the library name argument from the import:
local gl = require("libs/gl") ()
