Hello, Paul. Yes, I have read that part you mentioned, and it indeed gives the idea of a scene graph, no trouble there. My complaint, and mind you, that is not only about your book, is that I couldn't find explanations, not only on how to render simple objects, but the whole logical process behind it. And that's not only about knowing the theory of a scene graph. By reading a book on OSG, my objective is to be able to understand as thorough as possible the syntax, which I believe is more important than, for instance, memory management, which you deal with in your book even before you teach how to create geometry nodes.
Please, I didn't mean you any harm. Forgive me if I was a bit rude in my previous message. Renan M Z Mendes
