#include <fbxmanager.h>

Class Description

SDK object manager.

The SDK manager is in charge of:

scene element allocation, for example, FbxScene::Create(pSdkManager, "").
scene element deallocation, call FbxManager::Destroy() to deallocates all object created by the SDK manager.
scene element search and access, please see GlobalObjectManagement section.

It is possible to override memory allocation functions throughout the FBX SDK by providing system memory allocation functions using the handler set functions below. It must be done before the first FbxManager creation.

FbxSetMallocHandler(); FbxSetCallocHandler(); FbxSetReallocHandler(); FbxSetFreeHandler();

Upon destruction, all objects allocated by the SDK manager and not explicitly destroyed are destroyed as well. A derived class can be defined to allocate and deallocate specialized scene elements.

Remarks: You could create more than one SDK manager. However, it's better to NOT share the same object among different managers.

Examples:: Animation/main.cxx, Audio/main.cxx, Camera/main.cxx, Common/Common.cxx, Common/Common.h, ConvertScene/main.cxx, ExportDocument/main.cxx, ExportScene01/main.cxx, ExportScene02/main.cxx, ExportScene03/main.cxx, ExportScene04/main.cxx, ExportScene05/main.cxx, ExportShader/main.cxx, FileStream/main.cxx, ImportScene/main.cxx, Instances/main.cxx, Layers/main.cxx, MyOwnWriterReader/MyOwnReader.cxx, MyOwnWriterReader/MyOwnReader.h, MyOwnWriterReader/MyOwnWriter.cxx, MyOwnWriterReader/MyOwnWriter.h, MyOwnWriterReader/MyOwnWriterReader.cxx, MyOwnWriterReader/MyOwnWriterReader.h, Normals/main.cxx, Pivot/main.cxx, ProceduralTexture/main.cxx, StereoCamera/main.cxx, SwitchBinding/main.cxx, Transformations/main.cxx, UserProperties/main.cxx, UVSample/main.cxx, and ViewScene/SceneContext.h.
