Detailed Description

Class to import an FBX file into SDK objects.

Normally this class is used as is. But for very special needs a user can override Initialize() for special purpose.

An importer will select the appropriate reader to a particular file. Ex: When an importer must import an FBX 7 file, the importer will ask for all registered readers if an FBX 7 file reader is available, then if a reader is found, the importer will create the specialized FBX 7 reader and read the file. This way, an importer can "read" many different type of files like FBX 5/6/7, 3DS, Obj, Dxf, Collada, etc.

KFbxReader

Typical workflow for using the KFbxImporter class:

  1. create a SDKManager
  2. create an IOSettings object
  3. create an empty scene
  4. create an importer
  5. initialize the importer with a file name and IOSettings
  6. set numerous states, take information, defining how the importer will behave
  7. call KFbxImporter::Import() with an empty scene
     ex:
     // create a SdkManager
     KFbxSdkManager *lSdkManager = KFbxSdkManager::Create();
    
     // create an IOSettings object
     KFbxIOSettings * ios = KFbxIOSettings::Create(lSdkManager, IOSROOT );
    
     // set some IOSettings options 
     ios->SetBoolProp(IMP_FBX_MATERIAL, true);
     ios->SetBoolProp(IMP_FBX_TEXTURE,  true);
    
     // create an empty scene
     KFbxScene* lScene = KFbxScene::Create(lSdkManager,"");
    
     // Create an importer.
     KFbxImporter* lImporter = KFbxImporter::Create(lSdkManager, "");
    
     // Initialize the importer by providing a filename and the IOSettings to use
     lImporter->Initialize("C:\\myfile.fbx", -1, ios);
    
     // Import the scene.
     lImporter->Import(lScene); 
    
     // Destroy the importer.
     lImporter->Destroy(); 
    
Remarks:
According to the file suffix, a specialized reader will be created internally. Ex: for .fbx files a FBX Reader, for .3ds files, a 3ds reader, etc. Supported files formats: FBX 5/6/7 Binary & ASCII, Collada, DXF, OBJ, 3DS
Examples:

Common/Common.cxx, ExportScene05/main.cxx, MyOwnWriterReader/MyOwnWriterReader.cxx, MyOwnWriterReader/MyOwnWriterReader.h, UIExamples/Common/ImportExport.cxx, UIExamples/SceneTreeView/SDK_Utility.cxx, ViewScene/InitScene.cxx, and ViewScene/main.cxx.

Returns:
true on success, false otherwise.
Remarks:
To identify the error that occurred, call KFbxIO::GetLastErrorID(). If the imported file is password protected and the password is not set or wrong, function KFbxIO::GetLastErrorID() returns KFbxIO::ePASSWORD_ERROR.

Return true if the importer is currently importing.
Remarks:
This function will always return false if Import() was called with pNonBlocking set to false. This function should be used only in the context of pNonBlocking set to true. It is very important to periodically check if the import finished using this function, since it will also free up the thread's allocations when its done.
