LjES : 3D framework for LuaJIT on Raspberry Pi

LjES is a small 3D framework for Raspberry Pi built on top of the
OpenGL ES 2.0. LjES is written by 100% LuaJIT. The goal of this
framework is to make 3D graphics programming easy. The Raspbian
Linux disk image contains the LuaJIT-2.0. You don't need to install
any packages on Raspberry Pi to use LjES.

 o  LjES-2.0 supports Collada file loading and skeletal animation. 
 o  ColladaShape class can load the collada format exported by Blender.
 o  BonePhong shader supports up to 40 bones per mesh.

Usage :
  tar zxf ljes-2.01.tar.gz
  cd ljes-2.01
  cd examples
  luajit demo_spheres.lua
  luajit hand.lua

Example :

  package.path = "../LjES/?.lua;" .. package.path
  local demo = require("demo")

  demo.screen(0, 0)
  local aSpace = demo.getSpace()
  local eye = aSpace:addNode(nil, "eye")
  eye:setPosition(0, 0, 30)
  demo.backgroundColor(0.2, 0.2, 0.4)

  local shape = Shape:new()
  shape:donut(8, 3, 16, 16)
  shape:endShape()
  shape:shaderParameter("color", {1.0, 0.5, 0.6, 1.0})

  local node = aSpace:addNode(nil, "node1")
  node:setPosition(0, 0, 0)
  node:addShape(shape)

  function draw()
    node:rotateX(0.1)
    aSpace:draw(eye)
  end

  demo.loop(draw, true)
  demo.exit()
