Class Description

The clone manager is a utility for cloning entire networks of FbxObject.

Options are available for specifying how the clones inherit the connections of the original.

Networks of FbxObject (inter-connected objects by OO, OP, PO or PP connections) can be cloned. How the connections of clones are handled depends on mSrcPolicy and mExternalDstPolicy.

To clone FbxObject instances and their dependents, put them into a CloneSet and pass the CloneSet to this class:

 FbxCloneManager                  cloneManager;
 FbxCloneManager::CloneSet        cloneSet;
 FbxCloneManager::CloneSetElement defaultCloneOptions(FbxCloneManager::sConnectToClone,
                                       FbxCloneManager::sConnectToOriginal, FbxObject::eDeepClone);
 cloneSet.Insert(someObject, defaultCloneOptions);
 cloneManager.AddDependents(cloneSet, someObject, defaultCloneOptions);
 cloneManager.Clone(cloneSet, scene)

Member Typedef Documentation

The CloneSet is a collection of pointers to objects that will be cloned in Clone() Attached to each object is a CloneSetElement.

Its member variables dictate how the corresponding object will be cloned, and how it will inherit connections on the original object.

Member Function Documentation

static FbxObject* Clone ( const FbxObject pObject,
FbxObject pContainer = NULL 
) [static]

This function simplifies the process of cloning one object and all its depedency graph by automatically preparing the CloneSet and calling the Clone method using the code below:

 FbxCloneManager                  cloneManager;
 FbxCloneManager::CloneSet        cloneSet;
 FbxCloneManager::CloneSetElement defaultCloneOptions(FbxCloneManager::sConnectToClone,
                                                      0, 
                                                      FbxObject::eDeepClone);
 cloneSet.Insert(pObject, defaultCloneOptions);
 cloneManager.AddDependents(cloneSet, pObject, defaultCloneOptions);
 cloneManager.Clone(cloneSet, pContainer)
Parameters:
pObject Object to clone.
pContainer This object (typically a scene or document) will contain the new clones.
Returns:
The clone of pObject if all its depedency graph have been cloned successfully, NULL otherwise.
Remarks:
pContainer should not be an FbxNode used to group the cloned dependency graph. All the cloned objects of the graph will also connect to pContainer so all the node attributes will be interpreted as instances since they will connect to, at least, two FbxNodes. Also, if is left NULL the cloned object should be manually connected to the scene if it is to be saved to disk.

For example:

     FbxNode* lN = FbxNode::Create(lScene, "Clone");
     if (lN)
     {
         lN->LclTranslation.Set(FbxDouble3(50,0,0));
         lScene->GetRootNode()->AddChild(lN);

         FbxObject* cn = NULL;
         FbxObject* n = lScene->FindSrcObject("Mesh");
         if (n) cn = FbxCloneManager::Clone(n, lN);
     }

will generate the following (unexpected) dependency graph:

             "Clone" (FbxNode) 
                /   \               
               /      \
    "Mesh" (FbxNode) -- mesh (FbxNodeAttribute)

To generate the (expected) graph:

             "Clone" (FbxNode) 
                |
             "Mesh" (FbxNode) 
                |
              mesh (FbxNodeAttribute)

The correct code to use is:

     FbxNode* lN = FbxNode::Create(lScene, "Clone");
     if (lN)
     {
         lN->LclTranslation.Set(FbxDouble3(50,0,0));
         lScene->GetRootNode()->AddChild(lN);

         FbxObject* cn = NULL;
         FbxObject* n = lScene->FindSrcObject("Mesh");
         if (n) cn = FbxCloneManager::Clone(n);
         if (cn) lN->AddChild((FbxNode*)cn);
     }
virtual bool Clone ( CloneSet pSet,
FbxObject pContainer = NULL 
) const [virtual]

Clone all objects in the set using the given policies for duplication of connections.

Each CloneSetElement in the set will have its mObjectClone pointer set to the newly created clone.

Parameters:
pSet Set of objects to clone
pContainer This object (typically a scene or document) will contain the new clones
Returns:
true if all objects were cloned, false otherwise.
virtual void AddDependents ( CloneSet pSet,
const FbxObject pObject,
const CloneSetElement pCloneOptions = CloneSetElement(),
FbxCriteria  pTypes = FbxCriteria::ObjectType(FbxObject::ClassId),
int  pDepth = sMaximumCloneDepth 
) const [virtual]

Add all dependents of the given object to the CloneSet.

Dependents of items already in the set are ignored to prevent infinite recursion on cyclic dependencies.

Parameters:
pSet The set to add items.
pObject Object to add dependents to
pCloneOptions
pTypes Types of dependent objects to consider
pDepth Maximum recursive depth. Valid range is [0,sMaximumCloneDepth]
