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

Remarks
Generates a name.

◆ Node() [2/2]

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

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

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)

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

◆ setPosition() [2/2]

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 
)

◆ 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
inheritIf 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.

◆ 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]

◆ _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.

◆ _getDerivedOrientation()

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.

◆ _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
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 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()

void Ogre::Node::resetToInitialState ( void  )

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

◆ getInitialPosition()

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.

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.
