Getting a node’s properties as a point in space

FBX SDK Programmers Guide > Tutorial 2: Traversing the scene graph >

A node represents a point in space. The properties of KFbxNode include ones for the node’s translation, rotation, scaling (TRS). There are also properties that define limits on the TRS properties.

NoteThe TRS properties of a node object are stored as offsets to the TRS properties of the node’s parent, which in turn are stored as offsets of its parent’s TRS properties, and so on.

Properties that are generic to any point in space belong to KFbxNode.

SceneTreeView displays, for each node:

The node’s name (and node attribute type: seeGetting a node’s attribute type and contents).
The location of the node relative to the location of its parent node. This is expressed as the X, Y, and Z values of the node’stranslationfrom its parent.
Whether or not the scene element represented by the node is currently visible.

A node such as RootNode is an exception. It is simply a reference point in the tree: it doesn’t represent a point in space.

Below is the code for getting a node’s location.

Since the location is expressed as a translation from the parent node, we need to get the translation values. More precisely, we are getting thedefault translationvalues: the node’s actual location may be affected by limits on the X, Y, and Z values, by constraints, and by animation curves (fcurves). These are discussed inTutorial 3: Adding Textures, Materials, and Animation.

// to get a string from the node default translation values

KString GetDefaultTranslationInfo(

 const KFbxNode* pNode

 KFbxVector4 v4;

 ((KFbxNode*)pNode)->GetDefaultT(v4);

 return KString("Translation (X,Y,Z): ") + KString(v4.GetAt(0)) + ", " + KString(v4.GetAt(1)) + ", " + KString(v4.GetAt(2));

// to get a string from the node visibility value

KString GetNodeVisibility(

 const KFbxNode* pNode

 return KString("Visibility: ") + (pNode->GetVisibility() ? "Yes":"No");
