Detailed Description

Class representing a node in the scene graph.

Remarks: A SceneNode is a type of Node which is used to organise objects in a scene. It has the same hierarchical transformation properties of the generic Node class, but also adds the ability to attach world objects to the node, and stores hierarchical bounding volumes of the nodes in the tree. Child nodes are contained within the bounds of the parent, and so on down the tree, allowing for fast culling.

Reimplemented in Ogre::BspSceneNode.

◆ isInSceneGraph()

bool Ogre::SceneNode::isInSceneGraph ( void ) const

inline

Determines whether this node is in the scene graph, i.e.

whether it's ultimate ancestor is the root scene node.

◆ _notifyRootNode()

void Ogre::SceneNode::_notifyRootNode ( void )

inline

Notifies this SceneNode that it is the root scene node.

Remarks: Only SceneManager should call this!

◆ _update()

void Ogre::SceneNode::_update	(	bool	updateChildren,
		bool	parentHasChanged
	)

virtual

Internal method to update the Node.

Note: Updates this scene node and any relevant children to incorporate transforms etc. Don't call this yourself unless you are writing a SceneManager implementation.

Parameters

updateChildren	If true, the update cascades down to all children. Specify false if you wish to update children separately, e.g. because of a more selective SceneManager implementation.
parentHasChanged	This flag indicates that the parent transform has changed, so the child should retrieve the parent's transform and combine it with its own even if it hasn't changed itself.

Reimplemented from Ogre::Node.

Reimplemented in Ogre::PCZSceneNode, and Ogre::BspSceneNode.

◆ _updateBounds()

virtual void Ogre::SceneNode::_updateBounds ( void )

virtual

Tells the SceneNode to update the world bound info it stores.

◆ _findVisibleObjects()

void Ogre::SceneNode::_findVisibleObjects	(	Camera *	cam,
		RenderQueue *	queue,
		VisibleObjectsBoundsInfo *	visibleBounds,
		bool	includeChildren = `true`,
		bool	displayNodes = `false`,
		bool	onlyShadowCasters = `false`
	)

Internal method which locates any visible objects attached to this node and adds them to the passed in queue.

Remarks: Should only be called by a SceneManager implementation, and only after the _updat method has been called to ensure transforms and world bounds are up to date. SceneManager implementations can choose to let the search cascade automatically, or choose to prevent this and select nodes themselves based on some other criteria.

Parameters

cam	The active camera
queue	The SceneManager's rendering queue
visibleBounds	bounding information created on the fly containing all visible objects by the camera
includeChildren	If true, the call is cascaded down to all child nodes automatically.
displayNodes	If true, the nodes themselves are rendered as a set of 3 axes as well as the objects being rendered. For debugging purposes.
onlyShadowCasters

◆ _getWorldAABB()

const AxisAlignedBox& Ogre::SceneNode::_getWorldAABB ( void ) const

inline

Gets the axis-aligned bounding box of this node (and hence all subnodes).

Remarks: Recommended only if you are extending a SceneManager, because the bounding box returned from this method is only up to date after the SceneManager has called _update.

◆ getAttachedObjectIterator() [1/2]

ObjectIterator Ogre::SceneNode::getAttachedObjectIterator ( void )

inline

Deprecated:: use getAttachedObjects()

◆ getAttachedObjectIterator() [2/2]

ConstObjectIterator Ogre::SceneNode::getAttachedObjectIterator ( void ) const

inline

Deprecated:: use getAttachedObjects()

◆ getAttachedObjects()

const ObjectMap& Ogre::SceneNode::getAttachedObjects ( ) const

inline

Gets the creator of this scene node.

Remarks: This method returns the SceneManager which created this node. This can be useful for destroying this node.

◆ removeAndDestroyChild() [1/3]

void Ogre::SceneNode::removeAndDestroyChild ( const String & name )

This method removes and destroys the named child and all of its children.

Remarks: Unlike removeChild, which removes a single named child from this node but does not destroy it, this method destroys the child and all of it's children.

: Use this if you wish to recursively destroy a node as well as detaching it from it's parent. Note that any objects attached to the nodes will be detached but will not themselves be destroyed.

◆ removeAndDestroyChild() [2/3]

void Ogre::SceneNode::removeAndDestroyChild ( unsigned short index )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ removeAndDestroyChild() [3/3]

void Ogre::SceneNode::removeAndDestroyChild ( SceneNode * child )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ removeAndDestroyAllChildren()

void Ogre::SceneNode::removeAndDestroyAllChildren ( void )

Removes and destroys all children of this node.

Remarks: Use this to destroy all child nodes of this node and remove them from the scene graph. Note that all objects attached to this node will be detached but will not be destroyed.

◆ loadChildren()

void Ogre::SceneNode::loadChildren ( const String & filename )

◆ saveChildren()

void Ogre::SceneNode::saveChildren ( const String & filename )

Save the scene hierarchy starting at this node to file.

Parameters

filename destination file

◆ showBoundingBox()

void Ogre::SceneNode::showBoundingBox ( bool bShow )

inline

Allows the showing of the node's bounding box.

Remarks: Use this to show or hide the bounding box of the node.

◆ hideBoundingBox()

void Ogre::SceneNode::hideBoundingBox ( bool bHide )

inline

Deprecated:: this function will disappear with 1.13

◆ _addBoundingBoxToQueue()

void Ogre::SceneNode::_addBoundingBoxToQueue ( RenderQueue * queue )

Deprecated:: this function will disappear with 1.13

◆ getShowBoundingBox()

bool Ogre::SceneNode::getShowBoundingBox ( ) const

inline

This allows scene managers to determine if the node's bounding box should be added to the rendering queue.

Remarks: Scene Managers that implement their own _findVisibleObjects will have to check this flag and then use _addBoundingBoxToQueue to add the bounding box wireframe.

◆ createChildSceneNode() [1/2]

virtual SceneNode* Ogre::SceneNode::createChildSceneNode	(	const Vector3 &	translate = `Vector3::ZERO`,
		const Quaternion &	rotate = `Quaternion::IDENTITY`
	)

virtual

Creates an unnamed new SceneNode as a child of this node.

Parameters

translate	Initial translation offset of child relative to parent
rotate	Initial rotation relative to parent

Reimplemented in Ogre::PCZSceneNode.

◆ createChildSceneNode() [2/2]

virtual SceneNode* Ogre::SceneNode::createChildSceneNode	(	const String &	name,
		const Vector3 &	translate = `Vector3::ZERO`,
		const Quaternion &	rotate = `Quaternion::IDENTITY`
	)

virtual

Creates a new named SceneNode as a child of this node.

Remarks: This creates a child node with a given name, which allows you to look the node up from the parent which holds this collection of nodes.

Parameters

name	name of the node
translate	Initial translation offset of child relative to parent
rotate	Initial rotation relative to parent

Reimplemented in Ogre::PCZSceneNode.

◆ findLights()

void Ogre::SceneNode::findLights	(	LightList &	destList,
		Real	radius,
		uint32	lightMask = `0xFFFFFFFF`
	)		const

Allows retrieval of the nearest lights to the centre of this SceneNode.

Remarks: This method allows a list of lights, ordered by proximity to the centre of this SceneNode, to be retrieved. Can be useful when implementing MovableObject::queryLights and Renderable::getLights.

: Note that only lights could be affecting the frustum will take into account, which cached in scene manager.

See also: SceneManager::_getLightsAffectingFrustum; SceneManager::_populateLightList

Parameters

destList	List to be populated with ordered set of lights; will be cleared by this method before population.
radius	Parameter to specify lights intersecting a given radius of this SceneNode's centre.
lightMask	The mask with which to include / exclude lights

◆ setFixedYawAxis()

void Ogre::SceneNode::setFixedYawAxis	(	bool	useFixed,
		const Vector3 &	fixedAxis = `Vector3::UNIT_Y`
	)

Tells the node whether to yaw around it's own local Y axis or a fixed axis of choice.

Remarks: This method allows you to change the yaw behaviour of the node - by default, it yaws around it's own local Y axis when told to yaw with TS_LOCAL, this makes it yaw around a fixed axis. You only really need this when you're using auto tracking (see setAutoTracking, because when you're manually rotating a node you can specify the TransformSpace in which you wish to work anyway.

Parameters

useFixed	If true, the axis passed in the second parameter will always be the yaw axis no matter what the node orientation. If false, the node returns to it's default behaviour.
fixedAxis	The axis to use if the first parameter is true.

◆ yaw()

void Ogre::SceneNode::yaw	(	const Radian &	angle,
		TransformSpace	relativeTo = `TS_LOCAL`
	)

virtual

Rotate the node around the Y-axis.

Reimplemented from Ogre::Node.

◆ setDirection() [1/2]

void Ogre::SceneNode::setDirection	(	Real	x,
		Real	y,
		Real	z,
		TransformSpace	relativeTo = `TS_LOCAL`,
		const Vector3 &	localDirectionVector = `Vector3::NEGATIVE_UNIT_Z`
	)

Sets the node's direction vector ie it's local -z.

Remarks: Note that the 'up' vector for the orientation will automatically be recalculated based on the current 'up' vector (i.e. the roll will remain the same). If you need more control, use setOrientation.

Parameters

x,y,z	The components of the direction vector
relativeTo	The space in which this direction vector is expressed
localDirectionVector	The vector which normally describes the natural direction of the node, usually -Z

◆ setDirection() [2/2]

void Ogre::SceneNode::setDirection	(	const Vector3 &	vec,
		TransformSpace	relativeTo = `TS_LOCAL`,
		const Vector3 &	localDirectionVector = `Vector3::NEGATIVE_UNIT_Z`
	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ lookAt()

void Ogre::SceneNode::lookAt	(	const Vector3 &	targetPoint,
		TransformSpace	relativeTo,
		const Vector3 &	localDirectionVector = `Vector3::NEGATIVE_UNIT_Z`
	)

Points the local -Z direction of this node at a point in space.

Parameters

targetPoint	A vector specifying the look at point.
relativeTo	The space in which the point resides
localDirectionVector	The vector which normally describes the natural direction of the node, usually -Z

◆ setAutoTracking()

void Ogre::SceneNode::setAutoTracking	(	bool	enabled,
		SceneNode *const	target = `0`,
		const Vector3 &	localDirectionVector = `Vector3::NEGATIVE_UNIT_Z`,
		const Vector3 &	offset = `Vector3::ZERO`
	)

Enables / disables automatic tracking of another SceneNode.

Remarks: If you enable auto-tracking, this SceneNode will automatically rotate to point it's -Z at the target SceneNode every frame, no matter how it or the other SceneNode move. Note that by default the -Z points at the origin of the target SceneNode, if you want to tweak this, provide a vector in the 'offset' parameter and the target point will be adjusted.

Parameters

enabled	If true, tracking will be enabled and the next parameter cannot be null. If false tracking will be disabled and the current orientation will be maintained.
target	Pointer to the SceneNode to track. Make sure you don't delete this SceneNode before turning off tracking (e.g. SceneManager::clearScene will delete it so be careful of this). Can be null if and only if the enabled param is false.
localDirectionVector	The local vector considered to be the usual 'direction' of the node; normally the local -Z but can be another direction.
offset	If supplied, this is the target point in local space of the target node instead of the origin of the target node. Good for fine tuning the look at point.

◆ getAutoTrackTarget()

SceneNode* Ogre::SceneNode::getAutoTrackTarget ( void ) const

inline

Get the auto tracking target for this node, if any.

◆ getAutoTrackOffset()

const Vector3& Ogre::SceneNode::getAutoTrackOffset ( void ) const

inline

Get the auto tracking offset for this node, if the node is auto tracking.

◆ getAutoTrackLocalDirection()

const Vector3& Ogre::SceneNode::getAutoTrackLocalDirection ( void ) const

inline

Get the auto tracking local direction for this node, if it is auto tracking.

◆ _autoTrack()

void Ogre::SceneNode::_autoTrack ( void )

Internal method used by OGRE to update auto-tracking cameras.

◆ getParentSceneNode()

SceneNode* Ogre::SceneNode::getParentSceneNode ( void ) const

Gets the parent of this SceneNode.

◆ setVisible()

void Ogre::SceneNode::setVisible	(	bool	visible,
		bool	cascade = `true`
	)		const

Makes all objects attached to this node become visible / invisible.

Remarks: This is a shortcut to calling setVisible() on the objects attached to this node, and optionally to all objects attached to child nodes.

Parameters

visible	Whether the objects are to be made visible or invisible
cascade	If true, this setting cascades into child nodes too.

◆ flipVisibility()

void Ogre::SceneNode::flipVisibility ( bool cascade = true ) const

Inverts the visibility of all objects attached to this node.

Remarks: This is a shortcut to calling setVisible(!isVisible()) on the objects attached to this node, and optionally to all objects attached to child nodes.

Parameters

cascade If true, this setting cascades into child nodes too.

◆ setDebugDisplayEnabled()

void Ogre::SceneNode::setDebugDisplayEnabled	(	bool	enabled,
		bool	cascade = `true`
	)		const

Tells all objects attached to this node whether to display their debug information or not.

Remarks: This is a shortcut to calling setDebugDisplayEnabled() on the objects attached to this node, and optionally to all objects attached to child nodes.

Parameters

enabled	Whether the objects are to display debug info or not
cascade	If true, this setting cascades into child nodes too.
