The render tree (tree-like structure of node objects) determines the dependence of transformations of objects relative to each other, as well as the result displayed on the screen. Features of the W4 Game Engine render tree:
- A minimal render tree may consist of the root node only.
- Each node can have zero or more subnodes (“children”), but the node cannot have more than one “parent” (the root node does not have a parent).
- To display the object on the screen and/or recalculate the data, it need to be in the render tree.
- The hierarchy of built-in node types is shown in the diagram below.
