Detailed Description

Class representing a general-purpose node an articulated scene graph.

Remarks: A node in the scene graph is a node in a structured tree. A node contains information about the transformation which will apply to it and all of it's children. Child nodes can have transforms of their own, which are combined with their parent's transformations.

: This is an abstract class - concrete classes are based on this for specific purposes, e.g. SceneNode, Bone

Member Function Documentation

◆ getName()

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

inline

Returns the name of the node.

◆ getParent()

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

inline

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

◆ getOrientation()

const Quaternion& Ogre::Node::getOrientation ( ) const

inline

Returns a quaternion representing the nodes orientation.

◆ setOrientation() [1/2]

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

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
	)

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 )

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). The default is to inherit as with other transforms.

: Note that rotations are oriented around the node's origin.

◆ setPosition() [1/2]

void Ogre::Node::setPosition ( const Vector3 & pos )

inline

Gets the position of the node relative to it's parent.

◆ setScale() [1/2]

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

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.

◆ setScale() [2/2]

void Ogre::Node::setScale	(	Real	x,
		Real	y,
		Real	z
	)

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

◆ setInheritOrientation()

void Ogre::Node::setInheritOrientation ( bool inherit )

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). The default is to inherit as with other transforms.

◆ getInheritOrientation()

bool Ogre::Node::getInheritOrientation ( void ) const

inline

Returns true if this node is affected by orientation applied to the 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). The default is to inherit as with other transforms.; See setInheritOrientation for more info.

◆ setInheritScale()

void Ogre::Node::setInheritScale ( bool inherit )

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. 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.

Parameters

inherit If true, this node's scale will be affected by its parent's scale. If false, it will not be affected.

◆ getInheritScale()

bool Ogre::Node::getInheritScale ( void ) const

inline

Returns true if this node is affected by scaling factors applied to the parent node.

Remarks: See setInheritScale for more info.

References Ogre::Quaternion::IDENTITY, and Ogre::Vector3::ZERO.

◆ scale() [1/2]

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

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.

◆ scale() [2/2]

void Ogre::Node::scale	(	Real	x,

Remarks: This method translates the node by a vector which is relative to a custom set of axes.

Parameters

◆ getChildIterator() [1/2]

ChildNodeIterator Ogre::Node::getChildIterator ( void )

Retrieves an iterator for efficiently looping through all children of this node.

Remarks: Using this is faster than repeatedly calling getChild if you want to go through all (or most of) the children of this node. Note that the returned iterator is only valid whilst no children are added or removed from this node.

virtual

Removes all child Nodes attached to this node.

Does not delete the nodes, just detaches them from this parent, potentially to be reattached elsewhere.

Reimplemented in Ogre::OctreeNode.

◆ _setDerivedPosition()

void Ogre::Node::_setDerivedPosition ( const Vector3 & pos )

Sets the final world position of the node directly.

Remarks: It's advisable to use the local setPosition if possible

◆ _setDerivedOrientation()

void Ogre::Node::_setDerivedOrientation ( const Quaternion & q )

Sets the final world orientation of the node directly.

Remarks: It's advisable to use the local setOrientation if possible, this simply does the conversion for you.

Remarks: This method returns the full transformation matrix for this node, including the effect of any parent node transformations, provided they have been updated using the Node::_update method. This should only be called by a SceneManager which knows the derived transforms have been updated before calling this method. Applications using Ogre should just use the relative transforms.

◆ _update()

virtual void Ogre::Node::_update	(	bool	updateChildren,
		bool	parentHasChanged
	)

virtual

Internal method to update the Node.

Note: Updates this 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 in Ogre::SceneNode, Ogre::PCZSceneNode, and Ogre::BspSceneNode.

◆ setListener()

void Ogre::Node::setListener ( Listener * listener )

inline

Sets a listener for this Node.

◆ setInitialState()

void Ogre::Node::setInitialState ( void )

Sets the current transform of this node to be the 'initial state' ie that position / orientation / scale to be used as a basis for delta values used in keyframe animation.

Remarks: You never need to call this method unless you plan to animate this node. If you do plan to animate it, call this method once you've loaded the node with it's base state, ie the state on which all keyframes are based.

: If you never call this method, the initial state is the identity transform, ie do nothing.

◆ resetToInitialState()

◆ cancelUpdate()

void Ogre::Node::cancelUpdate ( Node * child )

Called by children to notify their parent that they no longer need an update.

◆ getDebugRenderable()

DebugRenderable* Ogre::Node::getDebugRenderable ( Real scaling )

Get a debug renderable for rendering the Node.

Referenced by Ogre::SceneNode::getAutoTrackLocalDirection().

◆ queueNeedUpdate()

static void Ogre::Node::queueNeedUpdate ( Node * n )

static

Queue a 'needUpdate' call to a node safely.

Remarks: You can't call needUpdate() during the scene graph update, e.g. in response to a Node::Listener hook, because the graph is already being updated, and update flag changes cannot be made reliably in that context. Call this method if you need to queue a needUpdate call in this case.

◆ processQueuedUpdates()

static void Ogre::Node::processQueuedUpdates ( void )

static

Process queued 'needUpdate' calls.

◆ setUserAny()

void Ogre::Node::setUserAny ( const Any & anything )

inline

Deprecated:: use UserObjectBindings::setUserAny via getUserObjectBindings() instead.

Sets any kind of user value on this object.

Remarks: This method allows you to associate any user value you like with this Node. This can be a pointer back to one of your own classes for instance.

◆ getUserAny()

const Any& Ogre::Node::getUserAny ( void ) const

inline

Deprecated:: use UserObjectBindings::getUserAny via getUserObjectBindings() instead.

Retrieves the custom user value associated with this object.

◆ getUserObjectBindings() [1/2]

UserObjectBindings& Ogre::Node::getUserObjectBindings ( )

inline

Return an instance of user objects binding associated with this class.

You can use it to associate one or more custom objects with this class instance.

See also: UserObjectBindings::setUserAny.

◆ getUserObjectBindings() [2/2]

const UserObjectBindings& Ogre::Node::getUserObjectBindings ( ) const

inline

Return an instance of user objects binding associated with this class.

You can use it to associate one or more custom objects with this class instance.

See also: UserObjectBindings::setUserAny.
