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

Constructor & Destructor Documentation

Ogre::Node::Node ( )

Constructor, should only be called by parent, not directly.

Remarks:: Generates a name.

Ogre::Node::Node ( const String & name )

Constructor, should only be called by parent, not directly.

Remarks:: Assigned a name.

virtual Ogre::Node::~Node ( ) [virtual]

Member Function Documentation

virtual const Quaternion& Ogre::Node::_getDerivedOrientation ( void ) const [virtual]

Gets the orientation of the node as derived from all parents.

virtual const Vector3& Ogre::Node::_getDerivedPosition ( void ) const [virtual]

Gets the position of the node as derived from all parents.

virtual const Vector3& Ogre::Node::_getDerivedScale ( void ) const [virtual]

Gets the scaling factor of the node as derived from all parents.

virtual const Matrix4& Ogre::Node::_getFullTransform ( void ) const [virtual]

Gets the full transformation matrix for this node.

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.

virtual void Ogre::Node::_setDerivedOrientation ( const Quaternion & q ) [virtual]

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.

virtual void Ogre::Node::_setDerivedPosition ( const Vector3 & pos ) [virtual]

Sets the final world position of the node directly.

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

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.

virtual void Ogre::Node::_updateFromParent ( void ) const [protected, virtual]

Triggers the node to update it's combined transforms.

: This method is called internally by Ogre to ask the node to update it's complete transformation based on it's parents derived transform.

virtual void Ogre::Node::addChild ( Node * child ) [virtual]

Adds a (precreated) child scene node to this node.

If it is attached to another node, it must be detached first.

Parameters:

child

The Node which is to become a child node of this one

virtual void Ogre::Node::cancelUpdate ( Node * child ) [virtual]

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

virtual Quaternion Ogre::Node::convertLocalToWorldOrientation ( const Quaternion & localOrientation ) [virtual]

Gets the world orientation of an orientation in the node local space useful for simple transforms that don't require a child node.

virtual Vector3 Ogre::Node::convertLocalToWorldPosition ( const Vector3 & localPos ) [virtual]

		const Vector3 &	translate = `Vector3::ZERO`,
		const Quaternion &	rotate = `Quaternion::IDENTITY`
	)			`[virtual]`

Creates a new named Node 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

virtual Node* Ogre::Node::createChild	(	const Vector3 &	translate = `Vector3::ZERO`,
		const Quaternion &	rotate = `Quaternion::IDENTITY`
	)			`[virtual]`

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

Parameters:

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

virtual Node* Ogre::Node::createChildImpl ( const String & name ) [protected, pure virtual]

Internal method for creating a new child node - must be overridden per subclass.

Implemented in Ogre::Bone, and Ogre::SceneNode.

virtual Node* Ogre::Node::createChildImpl ( void ) [protected, pure virtual]

Internal method for creating a new child node - must be overridden per subclass.

Implemented in Ogre::Bone, and Ogre::SceneNode.

virtual Node* Ogre::Node::getChild ( const String & name ) const [virtual]

Gets a pointer to a named child node.

virtual Node* Ogre::Node::getChild ( unsigned short index ) const [virtual]

Gets a pointer to a child node.

Remarks:: There is an alternate getChild method which returns a named child.

virtual ConstChildNodeIterator Ogre::Node::getChildIterator ( void ) const [virtual]

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. Thus you should not store this returned iterator for later use, nor should you add / remove children whilst iterating through it; store up changes for later. Note that calling methods on returned items in the iterator IS allowed and does not invalidate the iterator.

virtual ChildNodeIterator Ogre::Node::getChildIterator ( void ) [virtual]

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. Thus you should not store this returned iterator for later use, nor should you add / remove children whilst iterating through it; store up changes for later. Note that calling methods on returned items in the iterator IS allowed and does not invalidate the iterator.

virtual DebugRenderable* Ogre::Node::getDebugRenderable ( Real scaling ) [virtual]

Get a debug renderable for rendering the Node.

virtual bool Ogre::Node::getInheritOrientation ( void ) const [virtual]

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.

virtual bool Ogre::Node::getInheritScale ( void ) const [virtual]

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

Remarks:: See setInheritScale for more info.

virtual const Quaternion& Ogre::Node::getInitialOrientation ( void ) const [virtual]

Gets the initial orientation of this node, see setInitialState for more info.

virtual const Vector3& Ogre::Node::getInitialPosition ( void ) const [virtual]

Definition at line 754 of file OgreNode.h.

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

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.

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.

Definition at line 760 of file OgreNode.h.

virtual void Ogre::Node::needUpdate ( bool forceParentUpdate = false ) [virtual]

To be called in the event of transform changes to this node that require it's recalculation.

Remarks:: This not only tags the node state as being 'dirty', it also requests it's parent to know about it's dirtiness so it will get an update next time.

Parameters:

forceParentUpdate

Even if the node thinks it has already told it's parent, tell it anyway

Reimplemented in Ogre::Bone, and Ogre::TagPoint.

virtual void Ogre::Node::pitch	(	const Radian &	angle,
		TransformSpace	relativeTo = `TS_LOCAL`
	)			`[virtual]`

Rotate the node around the X-axis.

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

Process queued 'needUpdate' calls.

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.

virtual void Ogre::Node::removeAllChildren ( void ) [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.

virtual Node* Ogre::Node::removeChild ( const String & name ) [virtual]

Drops the named child from this node.

Remarks:: Does not delete the node, just detaches it from this parent, potentially to be reattached elsewhere.

virtual Node* Ogre::Node::removeChild ( Node * child ) [virtual]

Drops the specified child from this node.

Remarks:: Does not delete the node, just detaches it from this parent, potentially to be reattached elsewhere. There is also an alternate version which drops a named child from this node.

virtual Node* Ogre::Node::removeChild ( unsigned short index ) [virtual]

Drops the specified child from this node.

Remarks:: Does not delete the node, just detaches it from this parent, potentially to be reattached elsewhere. There is also an alternate version which drops a named child from this node.

virtual void Ogre::Node::requestUpdate	(	Node *	child,
		bool	forceParentUpdate = `false`
	)			`[virtual]`

Called by children to notify their parent that they need an update.

Parameters:

forceParentUpdate

Even if the node thinks it has already told it's parent, tell it anyway

virtual void Ogre::Node::resetOrientation ( void ) [virtual]

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.

virtual void Ogre::Node::resetToInitialState ( void ) [virtual]

Resets the position / orientation / scale of this node to it's initial state, see setInitialState for more info.

virtual void Ogre::Node::roll	(	const Radian &	angle,
		TransformSpace	relativeTo = `TS_LOCAL`
	)			`[virtual]`

Rotate the node around the Z-axis.

virtual void Ogre::Node::rotate	(	const Quaternion &	q,
		TransformSpace	relativeTo = `TS_LOCAL`
	)			`[virtual]`

Rotate the node around an aritrary axis using a Quarternion.

virtual void Ogre::Node::rotate	(	const Vector3 &	axis,
		const Radian &	angle,
		TransformSpace	relativeTo = `TS_LOCAL`
	)			`[virtual]`

Rotate the node around an arbitrary axis.

virtual void Ogre::Node::scale	(	Real	x,
		Real	y,
		Real	z
	)			`[virtual]`

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.

virtual void Ogre::Node::scale ( const Vector3 & scale ) [virtual]

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.

virtual void Ogre::Node::setInheritOrientation ( bool inherit ) [virtual]

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.

Parameters:

inherit

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

virtual void Ogre::Node::setInheritScale ( bool inherit ) [virtual]

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.

virtual void Ogre::Node::setInitialState ( void ) [virtual]

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.

virtual void Ogre::Node::setListener ( Listener * listener ) [virtual]

Sets a listener for this Node.

Remarks:: Note for size and performance reasons only one listener per node is allowed.

virtual void Ogre::Node::setOrientation	(	Real	w,
		Real	x,
		Real	y,
		Real	z
	)			`[virtual]`

Sets the orientation of this node via quaternion parameters.

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.

virtual void Ogre::Node::setOrientation ( const Quaternion & q ) [virtual]

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.

virtual void Ogre::Node::setScale	(	Real	x,
		Real	y,
		Real	z
	)			`[virtual]`

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.

virtual void Ogre::Node::setUserAny ( const Any & anything ) [virtual]

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.
