Node Class
Represents an element in the scene graph. A scene graph is a tree of Node objects. The tree management services are self contained in this class. Note the Aspose.3D SDK does not test the validity of the constructed scene graph. It is the responsibility of the caller to make sure that it does not generate cyclic graphs in a node hierarchy. Besides the tree management, this class defines all the properties required to describe the position of the object in the scene. This information include the basic Translation, Rotation and Scaling properties and the more advanced options for pivots, limits, and IK joints attributes such the stiffness and dampening. When it is first created, the Node object is "empty" (i.e: it is an object without any graphical representation that only contains the position information). In this state, it can be used to represent parents in the node tree structure but not much more. The normal use of this type of objects is to add them an entity that will specialize the node (see the "Entity"). The entity is an object in itself and is connected to the the Node. This also means that the same entity can be shared among multiple nodes. Camera, Light, Mesh, etc... are all entities and they all derived from the base class Entity.

Initializes a new instance of the Node class.
Public methodNode(String)
Initializes a new instance of the Node class.
Public methodNode(String, Entity)
Initializes a new instance of the Node class.
Public propertyAssetInfo
Per-node asset info
Public propertyChildNodes
Gets the children nodes.
Public propertyEntities
Gets all node entities.
Public propertyEntity
Gets or sets the first entity attached to this node, if sets, will clear other entities.
Public propertyExcluded
Gets or sets whether to exclude this node and all child nodes/entities during exporting.
Public propertyGlobalTransform
Gets the global transform.
Public propertyMaterial
Gets or sets the first material associated with this node, if sets, will clear other materials
Public propertyMaterials

Public methodCreateChildNode
Creates a child node
Public methodCreateChildNode(String)
Create a new child node with given node name
Public methodCreateChildNode(Entity)
Create a new child node with given entity attached
Public methodCreateChildNode(String, Entity)
Create a new child node with given node name
Public methodCreateChildNode(String, Entity, Material)
Create a new child node with given node name, and attach specified entity and a material
Public methodEquals (Inherited from Object.)
Public methodEvaluateGlobalTransform
