The main problem with openGL, is two group have been work in parallel. When we merge the demo work on my version of NBGLProgram. And we keep the version of Roassal3D, the demo do not work anymore, I expected as the code has been change, the small demo have been ported too. It is not working anymore sorry. I will spend time to fix that.
If you want to put energy in it. your are welcome. Should not be hard If you know the C openGL The calls should be correct just the API and "how" it should be used have been change, NBProgram NBBuffer NBShader have been change so the demo code should be updated too... By example the on: method do not exist anymore now we need to instantiate and set the stateTracker. I do not have a real internet connection. I take a look when I have one.
