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.

Member Function Documentation

◆ attachObject()

void AngelOgre::SceneNode::attachObject ( MovableObject@ obj )

Adds an instance of a scene object to this node.

Remarks: Scene objects can include Entity objects, Camera objects, Light objects, ParticleSystem objects etc. Anything that subclasses from MovableObject.

◆ createChildSceneNode() [1/2]

SceneNode AngelOgre::SceneNode::createChildSceneNode	(	const string &	name,
		const vector3 &	translate = `vector3(0.f, 0.f, 0.f)`,
		const Quaternion &	rotate = `quaternion()`
	)

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

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

◆ createChildSceneNode() [2/2]

SceneNode AngelOgre::SceneNode::createChildSceneNode	(	const vector3 &	translate = `vector3(0.f, 0.f, 0.f)`,
		const Quaternion &	rotate = `quaternion()`
	)

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

◆ detachAllObjects()

void AngelOgre::SceneNode::detachAllObjects ( void )

Detaches all objects attached to this node.

◆ detachObject() [1/3]

MovableObject AngelOgre::SceneNode::detachObject ( const string & name )

Detaches the named object from this node and returns a pointer to it.

◆ detachObject() [2/3]

void AngelOgre::SceneNode::detachObject ( MovableObject@ obj )

Detaches an object by pointer.

◆ detachObject() [3/3]

MovableObject AngelOgre::SceneNode::detachObject ( uint16 index )

Detaches the indexed object from this scene node.

Remarks: Detaches by index, see the alternate version to detach by name. Object indexes may change as other objects are added / removed.

◆ flipVisibility()

void AngelOgre::SceneNode::flipVisibility ( bool cascade = true )

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.

◆ getAttachedObject()

MovableObject AngelOgre::SceneNode::getAttachedObject ( const string & name )

Retrieves a pointer to an attached object.

Remarks: Retrieves by object name, see alternate version to retrieve by index.

◆ getAttachedObjects()

MovableObjectArray AngelOgre::SceneNode::getAttachedObjects ( )

The MovableObjects attached to this node.

This is a much faster way to go through all the objects attached to the node than using getAttachedObject.

◆ getAutoTrackLocalDirection()

const vector3& AngelOgre::SceneNode::getAutoTrackLocalDirection ( void )

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

◆ getAutoTrackOffset()

const vector3& AngelOgre::SceneNode::getAutoTrackOffset ( void )

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

◆ getAutoTrackTarget()

SceneNode AngelOgre::SceneNode::getAutoTrackTarget ( void )

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

◆ getCreator()

SceneManager AngelOgre::SceneNode::getCreator ( void ) const

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.

◆ getParentSceneNode()

SceneNode AngelOgre::SceneNode::getParentSceneNode ( void )

Gets the parent of this SceneNode.

◆ getShowBoundingBox()

bool AngelOgre::SceneNode::getShowBoundingBox ( ) const

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.

◆ hideBoundingBox()

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

Allows the overriding of the node's bounding box over the SceneManager's bounding box setting.

Remarks: Use this to override the bounding box setting of the node.

◆ isInSceneGraph()

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

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

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

◆ lookAt()

void AngelOgre::SceneNode::lookAt	(	const vector3 &	targetPoint,
		TransformSpace	relativeTo,
		const vector3 &	localDirectionVector = `vector3(0.f, 0.f, -1.f)`
	)

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

◆ removeAndDestroyAllChildren()

void AngelOgre::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.

◆ removeAndDestroyChild() [1/3]

void AngelOgre::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 AngelOgre::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.

◆ removeAndDestroyChild() [3/3]

void AngelOgre::SceneNode::removeAndDestroyChild ( uint16 index )

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

◆ setAutoTracking()

void AngelOgre::SceneNode::setAutoTracking	(	bool	enabled,
		SceneNode@ const	target = `0`,
		const vector3 &	localDirectionVector = `vector3(0.f, 0.f, -1.f)`,
		const vector3 &	offset = `vector3(0.f, 0.f, 0.f)`
	)

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.

◆ setDebugDisplayEnabled()

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

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.

◆ setDirection()

void AngelOgre::SceneNode::setDirection	(	const vector3 &	vec,
		TransformSpace	relativeTo = `TS_LOCAL`,
		const vector3 &	localDirectionVector = `vector3(0.f, 0.f, -1.f)`
	)

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

vec	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

◆ setFixedYawAxis()

void AngelOgre::SceneNode::setFixedYawAxis	(	bool	useFixed,
		const vector3 &	fixedAxis = `vector3(0.f, 1.f, 0.f)`
	)

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 floatly 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.

◆ setVisible()

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

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.

◆ showBoundingBox()

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

Allows the showing of the node's bounding box.

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

◆ yaw()

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

Rotate the node around the Y-axis.
