Hi Igor,

Thanks for your help.
Unfortunately, I do not have much time to dive in the implementation. A student is asking me how he can use OpenGL in Pharo. I would like to give him a simple starting point

What would be a simple piece of code that simply open a cube on the screen? I cannot ask him to go and study SourceCity or the implementation of NBOpenGL. He barely knows Smalltalk but he is very smart.

So, how to show a cube on the screen please?

Cheers,
Alexandre
