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

◆ _callMemoryChangeListeners()

virtual void Ogre::Node::_callMemoryChangeListeners ( )

pure virtual

Internal use, notifies all attached objects that our memory pointers (i.e.

Transform) may have changed (e.g. during cleanups, change of parent, etc)

Implemented in Ogre::SceneNode.

◆ _getDerivedOrientation()

virtual_l2 Quaternion Ogre::Node::_getDerivedOrientation ( ) const

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

Remarks: Assumes the caches are already updated. Will trigger an assert otherwise. See _getDerivedOrientationUpdated() if you need the update process to be guaranteed

◆ _getDerivedOrientationUpdated()

virtual_l2 Quaternion Ogre::Node::_getDerivedOrientationUpdated ( )

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

Remarks: Unlike _getDerivedOrientation, this function guarantees the cache stays up to date. It is strongly advised against calling this function for a large number of nodes. Refactor your queries so that they happen after SceneManager::UpdateAllTransforms() has been called

◆ _getDerivedPosition()

virtual_l2 Vector3 Ogre::Node::_getDerivedPosition ( ) const

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

Remarks: Assumes the caches are already updated. Will trigger an assert otherwise. See _getDerivedPositionUpdated() if you need the update process to be guaranteed

◆ _getDerivedPositionUpdated()

virtual_l2 Vector3 Ogre::Node::_getDerivedPositionUpdated ( )

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

Remarks: Unlike _getDerivedPosition, this function guarantees the cache stays up to date. It is strongly advised against calling this function for a large number of nodes. Refactor your queries so that they happen after SceneManager::UpdateAllTransforms() has been called

◆ _getDerivedScale()

virtual_l2 Vector3 Ogre::Node::_getDerivedScale ( ) const

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

Remarks: Assumes the caches are already updated. Will trigger an assert otherwise. See _getDerivedScaleUpdated() if you need the update process to be guaranteed

◆ _getDerivedScaleUpdated()

virtual_l2 Vector3 Ogre::Node::_getDerivedScaleUpdated ( )

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

Remarks: Unlike _getDerivedScale, this function guarantees the cache stays up to date. It is STRONGLY advised against calling this function for a large number of nodes. Refactor your queries so that they happen after SceneManager::UpdateAllTransforms() has been called

◆ _getFullTransform()

virtual_l2 FORCEINLINE const Matrix4& Ogre::Node::_getFullTransform ( ) const

inline

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. Assumes the caches are already updated

References Ogre::Transform::mDerivedTransform, Ogre::Transform::mIndex, and OGRE_ASSERT_MEDIUM.

◆ _getFullTransformUpdated()

virtual_l2 const Matrix4& Ogre::Node::_getFullTransformUpdated ( )

See _getDerivedScaleUpdated() remarks.

See also: _getFullTransform

◆ _getTransform()

Transform& Ogre::Node::_getTransform ( )

inline

Returns a direct access to the Transform state.

◆ _notifyStaticDirty()

virtual void Ogre::Node::_notifyStaticDirty ( ) const

virtual

Called by SceneManager when it is telling we're a static node being dirty Don't call this directly.

See also: SceneManager::notifyStaticDirty

Reimplemented in Ogre::SceneNode.

◆ _setDerivedOrientation()

virtual_l2 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.

◆ _setDerivedPosition()

virtual_l2 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

◆ _setNullNodeMemoryManager()

void Ogre::Node::_setNullNodeMemoryManager ( )

inline

Manually set the mNodeMemoryManager to a null ptr.

Remarks: Node doesn't follow the rule of three. This function is useful when you make multiple hard copies but only the destructor must release the mTransform only slots once.

◆ _updateChildren()

void Ogre::Node::_updateChildren ( )

Helper method to update the Node and all children.

Note: Updates this node and all children to incorporate transforms etc. Ogre never call it, preferring full update of all transforms, but there could be situations when scene modifications are known and so small that full update is inefficient.

◆ addChild()

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

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

◆ getChild() [1/2]

Node* Ogre::Node::getChild ( size_t index )

inline

Gets a pointer to a child node.

const Node* Ogre::Node::getChild ( size_t index ) const

inline

◆ getChildIterator() [1/2]

NodeVecIterator Ogre::Node::getChildIterator ( )

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.

◆ getChildIterator() [2/2]

ConstNodeVecIterator Ogre::Node::getChildIterator ( ) const

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.

◆ getIndestructibleByClearScene()

bool Ogre::Node::getIndestructibleByClearScene ( ) const

◆ getInheritOrientation()

virtual_l2 bool Ogre::Node::getInheritOrientation ( ) const

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.

◆ getInheritScale()

virtual_l2 bool Ogre::Node::getInheritScale ( ) const

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

Remarks: See setInheritScale for more info.

◆ getUserAny()

virtual OGRE_DEPRECATED const Any& Ogre::Node::getUserAny ( ) const

inlinevirtual

◆ migrateTo()

void Ogre::Node::migrateTo ( NodeMemoryManager * nodeMemoryManager )

nodeMemoryManager New memory manager to migrate to.

◆ numChildren()

size_t Ogre::Node::numChildren ( ) const

inline

Reports the number of child nodes under this one.

◆ pitch()

virtual_l2 void Ogre::Node::pitch	(	const Radian &	angle,
		TransformSpace	relativeTo = `TS_LOCAL`
	)

Rotate the node around the X-axis.

◆ removeAllChildren()

virtual void Ogre::Node::removeAllChildren ( )

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.

◆ removeChild()

virtual void 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.

: Asserts if child is not one of our children.

◆ resetOrientation()

virtual_l1 void Ogre::Node::resetOrientation ( )

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.

◆ roll()

virtual_l2 void Ogre::Node::roll	(	const Radian &	angle,
		TransformSpace	relativeTo = `TS_LOCAL`
	)

Rotate the node around the Z-axis.

◆ rotate() [1/2]

virtual_l2 void Ogre::Node::rotate	(	const Quaternion &	q,
		TransformSpace	relativeTo = `TS_LOCAL`
	)

Rotate the node around an arbitrary axis using a Quarternion.

◆ rotate() [2/2]

virtual_l2 void Ogre::Node::rotate	(	const Vector3 &	axis,
		const Radian &	angle,
		TransformSpace	relativeTo = `TS_LOCAL`
	)

Rotate the node around an arbitrary axis.

◆ scale() [1/2]

virtual_l2 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]

virtual_l2 void Ogre::Node::scale	(	Real	x,
		Real	y,
		Real	z
	)

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.

◆ setIndestructibleByClearScene()

void Ogre::Node::setIndestructibleByClearScene ( bool indestructible )

Calling SceneManager::clearScene won't destroy this node nor detach its objects (but may still destroy parent and children nodes if they're not indestructible) when this is true.

Remarks

This function provides trivial setter/getters rather than making mIndestructibleByClearScene public for two reasons:

It's rare called
There's a lot of value in debugging when a node is set to indestructible, which could happen by accident; and would thus leak.

◆ setInheritOrientation()

virtual_l2 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.

Parameters

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

◆ setInheritScale()

virtual_l2 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.

◆ setListener()

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

inlinevirtual

Sets a listener for this Node.

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

Reimplemented in Ogre::SceneNode.

◆ setName()

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

inline

Sets a custom name for this node.

Doesn't have to be unique

◆ setOrientation() [1/2]

virtual_l1 void Ogre::Node::setOrientation ( 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. Don't call this function too often, as we need to convert to SoA

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

◆ setOrientation() [2/2]

virtual_l1 void Ogre::Node::setOrientation	(	Real	w,
		Real	x,
		Real	y,
		Real	z
	)

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. Don't call this function too often, as we need to convert to SoA

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

◆ setPosition() [1/2]

virtual_l1 void Ogre::Node::setPosition ( const Vector3 & pos )

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

Remarks: Don't call this function too often, as we need to convert to SoA

◆ setPosition() [2/2]

virtual_l1 void Ogre::Node::setPosition	(	Real	x,
		Real	y,
		Real	z
	)

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

Remarks: Don't call this function too often, as we need to convert to SoA

◆ setScale() [1/2]

virtual_l1 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. Don't call this function too often, as we need to convert to SoA

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

◆ setScale() [2/2]

virtual_l1 void Ogre::Node::setScale	(	Real	x,
		Real	y,
		Real	z
	)

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. Don't call this function too often, as we need to convert to SoA

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

◆ setStatic()

virtual bool Ogre::Node::setStatic ( bool bStatic )

virtual

Turns this Node into static or dynamic.

Remarks: Switching between dynamic and static has some overhead and forces to update all static scene when converted to static. So don't do it frequently. Static objects are not updated every frame, only when requested explicitly. Use this feature if you plan to have this object unaltered for a very long times

: Changing this attribute to a node will cause to switch the attribute to all attached entities (but not children or parent nodes; it's perfectly valid and useful to have dynamic children of a static parent; although the opposite (static children, dynamic parent) is probably a bug.

Returns: True if setStatic made an actual change. False otherwise. Can fail because the object was already static/dynamic, or because switching is not supported

Reimplemented in Ogre::SceneNode.

◆ setUserAny()

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

inlinevirtual

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.

◆ translate() [1/4]

virtual_l2 void Ogre::Node::translate	(	const Matrix3 &	axes,

◆ mGlobalIndex

size_t Ogre::Node::mGlobalIndex

Index in the vector holding this node reference (could be our parent node, or a global array tracking all created nodes to avoid memory leaks).

Used for O(1) removals.

Remarks: It is the parent (or our creator) the one that sets this value, not ourselves. Do NOT modify it manually.

◆ mParentIndex

size_t Ogre::Node::mParentIndex

Index in the vector holding this node reference (could be our parent node, or a global array tracking all created nodes to avoid memory leaks).
