Frustrated with the documentation :(

I can't seem to find the information I need to find. It's like the core concepts aren't in the documentation. I've read through Torque X Core and Torque X 2d documentation, gone through all the examples and am still no closer to:

1. Understanding the scene graph
2. How objects get rendered
3. How to populate the torque object database from the objects in the scene. It's always empty.

Does anyone have a copy of the image that should be on this page, the image url is incorrect.

I see these a lot in the demo's but how do they get in the render pipeline? Are they pulled from their name (auto-magically)

public T2DSceneObject SceneObject
        {
            get { return Owner as T2DSceneObject; }
        }
        public T2DAnimatedSprite AnimatedSprite
        {
            get { return Owner as T2DAnimatedSprite; }
        }

I could do with a few examples or links to the relevant bit of documentation with conceptual explanations. Examples such as:

Create a component that renders a static sprite.
Create a component that renders an animated sprite.
Create a component that renders an animated sprite and changes between animations.
Create a component that adds link-points and attaches other objects from the scene graph.

I see all this going on in the demo's but just can't get the underlying methodology. I'm sure its simple once you get it but the tutorials don't fully explain what's going on.

Any help or links to the higher level documentation most gratefully recieved :)
