This section presents the FBX scene graph and its scene element organization.
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 factors.
A scene element's geometric transformation data is encapsulated by an instance of KFbxNode .
Consider a camera in the scene. In addition to its translation, rotation, and scaling parameters, it must also define the frame width, the frame height, its depth of field, its motion blur, etc.
A scene element's particular parameters are abstracted by a subclass of KFbxNodeAttribute, for example: KFbxMesh, KFbxLight, KFbxCamera, KFbxSkeleton, KFbxLine.
A scene element can therefore be defined by the combination of a KFbxNode and a KFbxNodeAttribute.
