Geometry

FbxGeometry is the base class for geometric objects which support control point deformations. Instances of FbxGeometry can be bound to FbxNode objects as node attributes to via FbxNode::SetNodeAttribute(). Classes which inherit from FbxGeometry include FbxMesh, FbxNurb, FbxPatch, and FbxLine. For a full list of the classes which inherit from FbxGeometry, consult the class hierarchy in the C++ Reference. For more information, consult the Meshes, Materials and Textures section.
