The SceneHelper type exposes the following members.

Methods

	Name	Description
	ClearLastPose	Clears the LastPoseWorld property of the current scene node (and its descendants).
	ClearLastScale	Clears the LastScaleWorld property of the current scene node (and its descendants).
	Contains	Determines whether whether a scene node contains another scene node in its subtree.
	GetAncestors	Gets the ancestors of the given scene node.
	GetChildren	Gets the children of the given scene node.
	GetDescendants(SceneNode)	Gets the descendants of the given scene node using a depth-first search.
	GetDescendants(SceneNode, Boolean)	Gets the descendants of the given scene node using a depth-first or a breadth-first search.
	GetLeaves	Gets the leaves of the scene node.
	GetRoot	Gets the root node.
	GetSceneNode	Gets a scene node by name from the subtree of the specified scene node.
	GetSelfAndAncestors	Gets the scene node and its ancestors scene.
	GetSubtree(SceneNode)	Gets the subtree (the given scene node and all of its descendants) using a depth-first search.
	GetSubtree(SceneNode, Boolean)	Gets the subtree (the given scene node and all of its descendants) using a depth-first or a breadth-first search.
	GetSubtreeAabb	Gets the AABB of the current subtree.
	LookAt(SceneNode, Vector3F, Vector3F)	Rotates the scene node so that it faces a certain direction (in world space).
	LookAt(SceneNode, Vector3F, Vector3F, Vector3F)	Moves and rotates the scene node so that it faces a certain direction (in world space).
	SetInstanceAlpha	Sets the opacity (alpha) of a scene node - see remarks.
	SetLastPose	Sets LastPoseWorld to the current PoseWorld.
	SetLastScale	Sets LastScaleWorld to the current ScaleWorld.
	SupportsInstanceAlpha	Determines whether the opacity of the scene node can be changed using SetInstanceAlpha(SceneNode, Single).
