[SceneGraph / SceneNode] What is the idea of this ?

[Arch1eN]

Hi !

I am reading SFML Game Development Book and i am really interested in SceneNodes, however i cant quite understand the concept. Thus i have few questions about this topic which. I was looking for some information on the internet, but i cant find any comprehensive article about it.

1. What is the idea of SceneNodes ?
2. Why is it called SceneNode and what "node" means in programming ?
3. What is the difference between SceneNodes and eg. StateManager ?
4. Could You describe the process of what SceneNode is doing ?

Any kind of help will be apreciated, and thanks in advance

1. What is the idea of SceneNodes ?

This is explained in the book, so can you be more specific concerning what you don't understand?

2. Why is it called SceneNode and what "node" means in programming ?

A node is an "element" in a tree data structure, or more general a graph. See Wikipedia.

3. What is the difference between SceneNodes and eg. StateManager ?

These are completely unrelated concepts, it doesn't make sense to ask that question.

4. Could You describe the process of what SceneNode is doing ?

Again, this is described in the book, so please read the chapter and tell us exactly which parts you struggle with.
