Getting child nodes recursively

 

Traversing the Scene Graph > 

Creating a scene and getting its root node

FBX applications using create the scene object immediately after creating the SDK Manager object:

// Declarations

KFbxSdkManager* gSdkManager = NULL;

KFbxScene*      gScene      = NULL;

const KFbxNode* gRootNode   = NULL;

...

// Create SDK manager to manage memory

gSdkManager = KFbxSdkManager::Create();

// Create scene object

gScene = KFbxScene::Create(gSdkManager, "");

In FBX, a scene has exactly one root node. KFbxScene has a function GetRootNode() which returns a reference to the root node of a scene:

//Get the scene’s root node

KFbxNode* gScene->GetRootNode();

All nodes in an FBX scene graph are, directly or indirectly, children of the root node:

The root node referenced by a KFBXScene object is not saved in an exported file. So if you want, for example, to apply a global translation to all objects in the scene:

1. Create a node (named, for example, RootNodeForGlobals) below RootNode and above the BallNode, HoopNode, etc.
2. Apply the global translation to RootNodeForGlobals.

RootNodeForGlobals will be saved with the global translation properties.
