The Skyline Globe Control has a hierarchy of node objects. Some types of nodes have child nodes of various types. Others are leaf nodes that cannot have anything below them in the Skyline Globe Control hierarchy.
The SGNode class provides objects hierarchy management in the Skyline Globe environment.
When working with objects in the 3D environment such as labels and polygons, the user is working with instances of SGNode, which have specific types.
To create new nodes, use one of the creation methods of the SGWorld.creator property. Once a new node is created, it is possible (not mandatory) to append it to the Skyline Globe Control root hierarchy (see SGWorld.root property). Doing so will allow arranging objects in a logical structure as well as traversing or searching the existing object.
In general, the SGNode class is loosely modeled after the Document Object Model (DOM) node object.
