Re: [Pharo-project] fun with NBOpenGL
Great to see 3D on Pharo again! Just a remark, somewhere there should be stated that directly loading vertex one by one with glVertex3f(..); is deprecated in the latest OpenGL. In favor of mechanisms that load the geometry to the renderer as a whole, as for example vertex buffer objects. In short, in the examples is ok to use, for learning the inner workings of OpenGL. Newer examples should make use of current practices of OpenGL. I think that Nehe examples web page states that. I think that a framework such as Lumiere, would be needed to provide higher abstractions and more efficient handling of geometry. Maybe when i finish my Phd, i can continue to work on it.

Excellent. Could you use large fonts :) The idea is that we should be able to see the code and to follow.

I'll go back and recreate the NeHe code for 2-6 using NBOpenGL as soon as I get your updated code installed.

I know it. But as said before in this topic, it is "tip of the iceberg". People who really know how to properly deal with modern OpenGL implementation should know it by themselves. The purpose of NBOpenGL is give them a way to do it in smalltalk. Not less but not more.

When you visit us I would like you to sit and pair program with erwan because we would like have a small code city Stef
