FBX SDK inheritance tree

FBX SDK Reference provides three kinds of inheritance graphs for the classes in FBX SDK:

• Click FBX SDK Reference > Class Hierarchy for a text-only representation of the full inheritance tree.
• Click FBX SDK Reference > Graphical Class Hierarchy for a diagram of the full inheritance tree.
• For any class that is involved in an inheritance relationship, the reference page will contain an inheritance diagram. Note that for classes with many levels of derived classes (notably KFbxObject), this diagram does not show all derived classes.

This topic will use the inheritance tree to guide you to the classes that deserve careful study.

Notes on the inheritance tree:

• Almost half of the classes in FBX SDK derive from KFbxObject. See FBX Objects and the reference page for class KFbxObject.
• Much of the data contained in an FBX object are stored in FBX properties. See FBX properties and the reference page for class KFbxProperty.
• The FBX scene graph is made up of instances of class KFbxNode. See FBX nodes: class KFbxNode, and the reference page for class KFbxNode.
• Whether an FBX node is a camera, a mesh, a NURBS, etc. is an attribute of the node, i.e., a node attribute. Classes for camera, mesh, NURBS, etc. are derived from KFbxNodeAttribute. See Node attributes: class KFbxNodeAttribute, and the reference page for class KFbxNodeAttribute.
• A take (sometimes called a take node) is a container for animation data (function curves, sometimes called FCurves). KFbxNode, KFbxNodeAttribute, and other classes involved in animation are derived from KFbxTakeNodeContainer. See Tutorial 4: Adding Animation and the reference page for class KFbxTakeNodeContainer.
• Many of the methods for importing and exporting files are in class KFbxIO, which is the base class for KFbxImporter and KFbxExporter. See Tutorial 1: Importing and Exporting, and the reference pages for KFbxIO, KFbxImporter, and KFbxExporter.
• KFbxStreamOptions is the base class for the classes that manage import and export options. See Tutorial 1: Importing and Exporting, and the reference page for class KFbxStreamOptions.
