# Nodes and the Scene Graph

This section presents the FBX scene graph and its scene element organization.

Nodes

The position of a scene element such as a mesh, a light, a camera, a skeleton, or a line can be described by a sequence of translations, rotations, and scaling operations. This geometric transformation data is encapsulated by FbxNode.

Node Attributes

Consider a camera in the scene. In addition to its translation, rotation, and scaling values, it can also define its frame width, frame height, depth of field, motion blur, etc. This additional data is encapsulated by FbxCamera, which is a subclass of FbxNodeAttribute. FbxMesh and FbxLight are also subclasses of FbxNodeAttribute, and may be bound to a FbxNode to specify their location in the scene.
