Nodes and the Scene Graph

This section presents the scene graph and scene element manipulation.

More specifically, this section will:

Introduce the FBX scene graph.
Present how to traverse the nodes in the scene.
Present how to manipulate the scene elements.
Present how the FBX SDK handles relationships between nodes.
Introduce coordinate systems as well as translation, rotation, and scaling.
Synthesize the contents of this section with ashort tutorial on how to merge two scenes.

Introducing the FBX scene
FBX nodes and node attributes
Creating a scene and getting its root node
Getting child nodes recursively
Most relationships are two-way
Getting the properties of a node as a point in space
Getting the attribute type and contents of a node
Merging Two Scenes
This topic presents how to merge two imported scenes. It also provides basic insight on manipulating a scene and the nodes within it, and will initiate the reader to the concept of connections and connection management.
Getting the transformation matrix for a node
How transformation matrices are computed
Creating metadata about nodes
