## 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.

## Member Function Documentation

virtual void Ogre::SceneNode::_addBoundingBoxToQueue | ( | RenderQueue * | queue | ) | `[virtual]`

Add the bounding box to the rendering queue.

void Ogre::SceneNode::_autoTrack | ( | void |  | ) |

Internal method used by OGRE to update auto-tracking cameras.

virtual void Ogre::SceneNode::_findVisibleObjects | ( | Camera * | cam,
|  | RenderQueue * | queue,
|  | VisibleObjectsBoundsInfo * | visibleBounds,
|  | bool | includeChildren = `true`,
|  | bool | displayNodes = `false`,
|  | bool | onlyShadowCasters = `false` |
| ) |  |  | `[virtual]`

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:

  | cam | The active camera
  | queue | The SceneManager's rendering queue
  | visibleBounds | bounding information created on the fly containing all visible objects by the camera
  | includeChildren | If true, the call is cascaded down to all child nodes automatically.
  | displayNodes | If true, the nodes themselves are rendered as a set of 3 axes as well as the objects being rendered. For debugging purposes.

virtual const Quaternion& Ogre::Node::_getDerivedOrientation | ( | void |  | ) | const`[virtual, inherited]`

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

virtual const Vector3& Ogre::Node::_getDerivedPosition | ( | void |  | ) | const`[virtual, inherited]`

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

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

virtual const Matrix4& Ogre::Node::_getFullTransform | ( | void |  | ) | const`[virtual, inherited]`

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 const AxisAlignedBox& Ogre::SceneNode::_getWorldAABB | ( | void |  | ) | const`[virtual]`

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.

virtual void Ogre::SceneNode::_notifyRootNode | ( | void |  | ) | `[virtual]`

Notifies this SceneNode that it is the root scene node.

Remarks:
  Only SceneManager should call this!

Definition at line 169 of file OgreSceneNode.h.

virtual void Ogre::Node::_setDerivedOrientation | ( | const Quaternion & | q | ) | `[virtual, inherited]`

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, inherited]`

Sets the final world position of the node directly.

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

virtual 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:

  | 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 xform has changed, so the child should retrieve the parent's xform and combine it with its own even if it hasn't changed itself.

Reimplemented from Ogre::Node.

virtual void Ogre::SceneNode::_updateBounds | ( | void |  | ) | `[virtual]`

Tells the SceneNode to update the world bound info it stores.

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

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, inherited]`

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

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

  | destList | List to be populated with ordered set of lights; will be cleared by this method before population.
  | radius | Parameter to specify lights intersecting a given radius of this SceneNode's centre.
  | lightMask | The mask with which to include / exclude lights

virtual void Ogre::SceneNode::flipVisibility | ( | bool | cascade = `true` | ) | `[virtual]`

Inverts the visibility of all objects attached to this node.

Remarks:
  This is a shortcut to calling setVisible(!isVisible()) on the objects attached to this node, and optionally to all objects attached to child nodes.

Parameters:

  | cascade | If true, this setting cascades into child nodes too.

virtual MovableObject* Ogre::SceneNode::getAttachedObject | ( | const String & | name | ) | `[virtual]`

Retrieves a pointer to an attached object.

Remarks:
  Retrieves by object name, see alternate version to retrieve by index.

virtual MovableObject* Ogre::SceneNode::getAttachedObject | ( | unsigned short | index | ) | `[virtual]`

Retrieves a pointer to an attached object.

Remarks:
  Retrieves by index, see alternate version to retrieve by name. The index of an object may change as other objects are added / removed.

virtual ObjectIterator Ogre::SceneNode::getAttachedObjectIterator | ( | void |  | ) | `[virtual]`

Retrieves an iterator which can be used to efficiently step through the objects attached to this node.

Remarks:
  This is a much faster way to go through all the objects attached to the node than using getAttachedObject. But the iterator returned is only valid until a change is made to the collection (ie an addition or removal) so treat the returned iterator as transient, and don't add / remove items as you go through the iterator, save changes until the end, or retrieve a new iterator after making the change. Making changes to the object returned through the iterator is OK though.

virtual ConstObjectIterator Ogre::SceneNode::getAttachedObjectIterator | ( | void |  | ) | const`[virtual]`

Retrieves an iterator which can be used to efficiently step through the objects attached to this node.

Remarks:
  This is a much faster way to go through all the objects attached to the node than using getAttachedObject. But the iterator returned is only valid until a change is made to the collection (ie an addition or removal) so treat the returned iterator as transient, and don't add / remove items as you go through the iterator, save changes until the end, or retrieve a new iterator after making the change. Making changes to the object returned through the iterator is OK though.

virtual const Vector3& Ogre::SceneNode::getAutoTrackLocalDirection | ( | void |  | ) | `[virtual]`

Definition at line 423 of file OgreSceneNode.h.

virtual SceneNode* Ogre::SceneNode::getAutoTrackTarget | ( | void |  | ) | `[virtual]`

Get the auto tracking target for this node, if any.

Definition at line 421 of file OgreSceneNode.h.

virtual Node* Ogre::Node::getChild | ( | unsigned short | index | ) | const`[virtual, inherited]`

Gets a pointer to a child node.

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

virtual Node* Ogre::Node::getChild | ( | const String & | name | ) | const`[virtual, inherited]`

Gets a pointer to a named child node.

virtual ChildNodeIterator Ogre::Node::getChildIterator | ( | void |  | ) | `[virtual, inherited]`

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 ConstChildNodeIterator Ogre::Node::getChildIterator | ( | void |  | ) | const`[virtual, inherited]`

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.

SceneManager* Ogre::SceneNode::getCreator | ( | void |  | ) | const

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.

Definition at line 247 of file OgreSceneNode.h.

virtual DebugRenderable* Ogre::SceneNode::getDebugRenderable | ( |  | ) | `[virtual]`

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

virtual DebugRenderable* Ogre::Node::getDebugRenderable | ( | Real | scaling | ) | `[virtual, inherited]`

Get a debug renderable for rendering the Node.

virtual bool Ogre::Node::getInheritOrientation | ( | void |  | ) | const`[virtual, inherited]`

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, inherited]`

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

Gets the scaling factor of this node.

virtual bool Ogre::SceneNode::getShowBoundingBox | ( |  | ) | const`[virtual]`

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.

Real Ogre::Node::getSquaredViewDepth | ( | const Camera * | cam | ) | const`[inherited]`

Helper function, get the squared view depth.

virtual const Any& Ogre::Node::getUserAny | ( | void |  | ) | const`[virtual, inherited]`

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

Definition at line 754 of file OgreNode.h.

const UserObjectBindings& Ogre::Node::getUserObjectBindings | ( |  | ) | const`[inherited]`

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.

Definition at line 766 of file OgreNode.h.

UserObjectBindings& Ogre::Node::getUserObjectBindings | ( |  | ) | `[inherited]`

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.

|  | TransformSpace | relativeTo,
|  | const Vector3 & | localDirectionVector = `Vector3::NEGATIVE_UNIT_Z` |
| ) |  |  | `[virtual]`

virtual void Ogre::Node::needUpdate | ( | bool | forceParentUpdate = `false` | ) | `[virtual, inherited]`

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 unsigned short Ogre::SceneNode::numAttachedObjects | ( | void |  | ) | const`[virtual]`

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

Rotate the node around the X-axis.

static void Ogre::Node::processQueuedUpdates | ( | void |  | ) | `[static, inherited]`

Process queued 'needUpdate' calls.

static void Ogre::Node::queueNeedUpdate | ( | Node * | n | ) | `[static, inherited]`

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, inherited]`

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 void Ogre::SceneNode::removeAndDestroyAllChildren | ( | void |  | ) | `[virtual]`

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.

virtual void Ogre::SceneNode::removeAndDestroyChild | ( | const String & | name | ) | `[virtual]`

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.

virtual void Ogre::SceneNode::removeAndDestroyChild | ( | unsigned short | index | ) | `[virtual]`

This method removes and destroys the 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.

virtual Node* Ogre::Node::removeChild | ( | const String & | name | ) | `[virtual, inherited]`

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, inherited]`

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, inherited]`

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, inherited]`

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, 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). 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, inherited]`

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, inherited]`

Rotate the node around the Z-axis.

virtual void Ogre::Node::rotate | ( | const Vector3 & | axis,

|  | TransformSpace | relativeTo = `TS_LOCAL` |
| ) |  |  | `[virtual, inherited]`

Rotate the node around an arbitrary axis.

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

Rotate the node around an aritrary axis using a Quarternion.

virtual void Ogre::Node::scale | ( | const Vector3 & | scale | ) | `[virtual, 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.

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

virtual void Ogre::SceneNode::setAutoTracking | ( | bool | enabled,
|  | SceneNode * | target = `0`,
|  | const Vector3 & | localDirectionVector = `Vector3::NEGATIVE_UNIT_Z`,
|  | const Vector3 & | offset = `Vector3::ZERO` |
| ) |  |  | `[virtual]`

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:

  | enabled | If 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.
  | target | Pointer 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.
  | localDirectionVector | The local vector considered to be the usual 'direction' of the node; normally the local -Z but can be another direction.
  | offset | If 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.

virtual void Ogre::SceneNode::setDebugDisplayEnabled | ( | bool | enabled,
|  | bool | cascade = `true` |
| ) |  |  | `[virtual]`

Tells all objects attached to this node whether to display their debug information or not.

Remarks:
  This is a shortcut to calling setDebugDisplayEnabled() on the objects attached to this node, and optionally to all objects attached to child nodes.

Parameters:

  | enabled | Whether the objects are to display debug info or not
  | cascade | If true, this setting cascades into child nodes too.

virtual void Ogre::SceneNode::setDirection | ( | Real | x,
|  | Real | y,
|  | Real | z,
|  | TransformSpace | relativeTo = `TS_LOCAL`,
|  | const Vector3 & | localDirectionVector = `Vector3::NEGATIVE_UNIT_Z` |
| ) |  |  | `[virtual]`

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,z | The components of the direction vector
  | relativeTo | The space in which this direction vector is expressed
  | localDirectionVector | The vector which normally describes the natural direction of the node, usually -Z

virtual void Ogre::SceneNode::setDirection | ( | const Vector3 & | vec,
|  | TransformSpace | relativeTo = `TS_LOCAL`,
|  | const Vector3 & | localDirectionVector = `Vector3::NEGATIVE_UNIT_Z` |
| ) |  |  | `[virtual]`

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:

  | vec | The direction vector
  | relativeTo | The space in which this direction vector is expressed
  | localDirectionVector | The vector which normally describes the natural direction of the node, usually -Z

virtual void Ogre::SceneNode::setFixedYawAxis | ( | bool | useFixed,
|  | const Vector3 & | fixedAxis = `Vector3::UNIT_Y` |
| ) |  |  | `[virtual]`

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:

  | useFixed | If 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.
  | fixedAxis | The axis to use if the first parameter is true.

virtual void Ogre::Node::setInheritOrientation | ( | bool | inherit | ) | `[virtual, 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). 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, 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. 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, inherited]`

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::SceneNode::setInSceneGraph | ( | bool | inGraph | ) | `[protected, virtual]`

Internal method for setting whether the node is in the scene graph.

virtual void Ogre::Node::setListener | ( | Listener * | listener | ) | `[virtual, inherited]`

Definition at line 660 of file OgreNode.h.

virtual void Ogre::Node::setOrientation | ( | const Quaternion & | q | ) | `[virtual, 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.

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

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.

Reimplemented from Ogre::Node.

virtual void Ogre::Node::setPosition | ( | const Vector3 & | pos | ) | `[virtual, inherited]`

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

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

virtual void Ogre::Node::setScale | ( | const Vector3 & | scale | ) | `[virtual, 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.

virtual void Ogre::Node::setUserAny | ( | const Any & | anything | ) | `[virtual, inherited]`

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.

virtual void Ogre::SceneNode::setVisible | ( | bool | visible,
|  | bool | cascade = `true` |
| ) |  |  | `[virtual]`

Remarks:
  This is a shortcut to calling setVisible() on the objects attached to this node, and optionally to all objects attached to child nodes.

Parameters:

  | visible | Whether the objects are to be made visible or invisible
  | cascade | If true, this setting cascades into child nodes too.

virtual void Ogre::SceneNode::showBoundingBox | ( | bool | bShow | ) | `[virtual]`

                      1 0 0
                      0 1 0
                      0 0 1
  i.e. the identity matrix.

| ) |  |  | `[virtual, inherited]`

Moves the node along arbitrary axes.

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

Parameters:

  | axes | A 3x3 Matrix containg 3 column vectors each representing the axes X, Y and Z respectively. In this format the standard cartesian axes would be expressed as:
                      1 0 0
                      0 1 0
                      0 0 1

| ) |  |  | `[virtual, inherited]`

Moves the node along the Cartesian axes.

  This method moves the node by the supplied vector along the world Cartesian axes, i.e. along world x,y,z

Parameters:

  | x |
  | y |
  | z | Real x, y and z values representing the translation.
  | relativeTo | The space which this transform is relative to.

void Ogre::SceneNode::updateFromParentImpl | ( | void |  | ) | const`[protected, virtual]`

Class-specific implementation of _updateFromParent.

Remarks:
  Splitting the implementation of the update away from the update call itself allows the detail to be overridden without disrupting the general sequence of updateFromParent (e.g. raising events)

.

Reimplemented from Ogre::Node.

virtual void Ogre::SceneNode::yaw | ( | const Radian & | angle,
|  | TransformSpace | relativeTo = `TS_LOCAL` |
| ) |  |  | `[virtual]`
