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.

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

Reimplemented in Ogre::BspSceneNode.

◆ detachObject() [2/3]

virtual void Ogre::SceneNode::detachObject ( MovableObject obj)
virtual

Detaches an object by pointer.

◆ detachObject() [3/3]

virtual MovableObject* Ogre::SceneNode::detachObject ( const String name)
virtual

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

Reimplemented in Ogre::BspSceneNode.

◆ detachAllObjects()

virtual void Ogre::SceneNode::detachAllObjects ( void  )
virtual

Detaches all objects attached to this node.

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
updateChildrenIf 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.
parentHasChangedThis 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
camThe active camera
queueThe SceneManager's rendering queue
visibleBoundsbounding information created on the fly containing all visible objects by the camera
includeChildrenIf true, the call is cascaded down to all child nodes automatically.
displayNodesIf true, the nodes themselves are rendered as a set of 3 axes as well as the objects being rendered. For debugging purposes.

◆ _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

◆ getAttachedObjectIterator() [2/2]

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

◆ getAttachedObjects()

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

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

◆ getCreator()

SceneManager* Ogre::SceneNode::getCreator ( void  ) 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.

◆ 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

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.

◆ _addBoundingBoxToQueue()

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

Add the bounding box to the rendering queue.

◆ 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.

References Ogre::Quaternion::IDENTITY.

◆ 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
translateInitial translation offset of child relative to parent
rotateInitial 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
namename of the node
translateInitial translation offset of child relative to parent
rotateInitial 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
destListList to be populated with ordered set of lights; will be cleared by this method before population.
radiusParameter to specify lights intersecting a given radius of this SceneNode's centre.
lightMaskThe 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
useFixedIf 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.
fixedAxisThe 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,zThe components of the direction vector
relativeToThe space in which this direction vector is expressed
localDirectionVectorThe 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
targetPointA vector specifying the look at point.
relativeToThe space in which the point resides
localDirectionVectorThe 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
enabledIf 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.
targetPointer 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.
localDirectionVectorThe local vector considered to be the usual 'direction' of the node; normally the local -Z but can be another direction.
offsetIf 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  )
inline

◆ getDebugRenderable() [1/2]

DebugRenderable* Ogre::SceneNode::getDebugRenderable ( )

As Node::getDebugRenderable, except scaling is automatically determined.

◆ getName()

const String& Ogre::Node::getName ( void  ) const
inlineinherited

Returns the name of the node.

◆ getParent()

Node* Ogre::Node::getParent ( void  ) const
inlineinherited

Gets this node's parent (NULL if this is the root).

inlineinherited

Returns a quaternion representing the nodes orientation.

◆ setOrientation() [1/2]

void Ogre::Node::setOrientation ( const Quaternion q)
inherited

Sets the orientation of this node via a quaternion.

Remarks
Orientations, unlike other transforms, are not always inherited by child nodes. Whether or not orientations affect the orientation of the child nodes depends on the setInheritOrientation option of the child. In some cases you want a orientating of a parent node to apply to a child node (e.g. where the child node is a part of the same object, so you want it to be the same relative orientation based on the parent's orientation), but not in other cases (e.g. where the child node is just for positioning another object, you want it to maintain it's own orientation). The default is to inherit as with other transforms.
Note that rotations are oriented around the node's origin.

◆ setOrientation() [2/2]

void Ogre::Node::setOrientation ( Real  w,
Real  x,
Real  y,
Real  z 
)
inherited

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

◆ resetOrientation()

void Ogre::Node::resetOrientation ( void  )
inherited

Resets the nodes orientation (local axes as world axes, no rotation).

Remarks
Orientations, unlike other transforms, are not always inherited by child nodes. Whether or not orientations affect the orientation of the child nodes depends on the setInheritOrientation option of the child. In some cases you want a orientating of a parent node to apply to a child node (e.g. where the child node is a part of the same object, so you want it to be the same relative orientation based on the parent's orientation), but not in other cases (e.g. where the child node is just for positioning another object, you want it to maintain it's own orientation).

◆ setScale() [1/2]

void Ogre::Node::setScale ( const Vector3 scale)
inherited

Sets the scaling factor applied to this node.

Remarks
Scaling factors, unlike other transforms, are not always inherited by child nodes. Whether or not scalings affect the size of the child nodes depends on the setInheritScale option of the child. In some cases you want a scaling factor of a parent node to apply to a child node (e.g. where the child node is a part of the same object, so you want it to be the same relative size based on the parent's size), but not in other cases (e.g. where the child node is just for positioning another object, you want it to maintain it's own size). The default is to inherit as with other transforms.
Note that like rotations, scalings are oriented around the node's origin.

inherited

Tells the node whether it should inherit orientation from it's parent node.

Remarks
Orientations, unlike other transforms, are not always inherited by child nodes. Whether or not orientations affect the orientation of the child nodes depends on the setInheritOrientation option of the child. In some cases you want a orientating of a parent node to apply to a child node (e.g. where the child node is a part of the same object, so you want it to be the same relative orientation based on the parent's orientation), but not in other cases (e.g. where the child node is just for positioning another object, you want it to maintain it's own orientation).

inherited

Tells the node whether it should inherit scaling factors from it's parent node.

Remarks
Scaling factors, unlike other transforms, are not always inherited by child nodes. Whether or not scalings affect the size of the child nodes depends on the setInheritScale option of the child.

◆ scale() [1/2]

void Ogre::Node::scale ( const Vector3 scale)
inherited

Scales the node, combining it's current scale with the passed in scaling factor.

Remarks
This method applies an extra scaling factor to the node's existing scale, (unlike setScale which overwrites it) combining it's current scale with the new one. E.g. calling this method twice with Vector3(2,2,2) would have the same effect as setScale(Vector3(4,4,4)) if the existing scale was 1.
Note that like rotations, scalings are oriented around the node's origin.
