Member Function Documentation

virtual void Ogre::SceneNode::_addBoundingBoxToQueue RenderQueue queue  )  [virtual, inherited]
 

Add the bounding box to the rendering queue.

virtual void Ogre::OctreeNode::_addToRenderQueue Camera cam,
RenderQueue q,
bool  onlyShadowCasters
[virtual]
 

Adds all the attached scenenodes to the render queue.

void Ogre::SceneNode::_autoTrack void   )  [inherited]
 

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

virtual void Ogre::SceneNode::_findVisibleObjects Camera cam,
RenderQueue queue,
bool  includeChildren = true,
bool  displayNodes = false,
bool  onlyShadowCasters = false
[virtual, inherited]
 

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
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.

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

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

virtual 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.

AxisAlignedBox& Ogre::OctreeNode::_getLocalAABB  ) 
 

Returns the local bounding box of this OctreeNode.

Remarks:
This is used to render the bounding box, rather then the global.

Definition at line 101 of file OgreOctreeNode.h.

References mLocalAABB.

virtual AxisAlignedBox Ogre::SceneNode::_getWorldAABB void   )  const [virtual, inherited]
 

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.

bool Ogre::OctreeNode::_isIn AxisAlignedBox box  ) 
 

Determines if the center of this node is within the given box.

virtual void Ogre::SceneNode::_notifyRootNode void   )  [virtual, inherited]
 

Notifies this SceneNode that it is the root scene node.

Remarks:
Only SceneManager should call this!

Definition at line 159 of file OgreSceneNode.h.

void Ogre::OctreeNode::_removeNodeAndChildren  )  [protected]
 

virtual void Ogre::SceneNode::_update bool  updateChildren,
bool  parentHasChanged
[virtual, inherited]
 

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.

Reimplemented in Ogre::BspSceneNode.

void Ogre::OctreeNode::_updateBounds void   )  [protected, virtual]
 

Internal method for updating the bounds for this OctreeNode.

Remarks:
This method determines the bounds solely from the attached objects, not any children. If the node has changed it's bounds, it is removed from its current octree, and reinserted into the tree.

Reimplemented from Ogre::SceneNode.

virtual void Ogre::Renderable::_updateCustomGpuParameter const GpuProgramParameters::AutoConstantEntry constantEntry,
GpuProgramParameters params
const [virtual, inherited]
 

Update a custom GpuProgramParameters constant which is derived from information only this Renderable knows.

Remarks:
This method allows a Renderable to map in a custom GPU program parameter based on it's own data. This is represented by a GPU auto parameter of ACT_CUSTOM, and to allow there to be more than one of these per Renderable, the 'data' field on the auto parameter will identify which parameter is being updated. The implementation of this method must identify the parameter being updated, and call a 'setConstant' method on the passed in GpuProgramParameters object, using the details provided in the incoming auto constant setting to identify the index at which to set the parameter.
You do not need to override this method if you're using the standard sets of data associated with the Renderable as provided by setCustomParameter and getCustomParameter. By default, the implementation will map from the value indexed by the 'constantEntry.data' parameter to a value previously set by setCustomParameter. But custom Renderables are free to override this if they want, in any case.
Parameters:
constantEntry The auto constant entry referring to the parameter being updated
params The parameters object which this method should call to set the updated parameters.

Reimplemented in Ogre::TerrainRenderable.

Definition at line 219 of file OgreRenderable.h.

Reimplemented in Ogre::TagPoint.

virtual void Ogre::Node::_weightedTransform Real  weight,
const Vector3 translate,
const Quaternion rotate,
const Vector3 scale
[virtual, inherited]
 

Internal weighted transform method.

Remarks:
This method transforms a Node by a weighted amount from it's initial state. If weighted transforms have already been applied, the previous transforms and this one are blended together based on their relative weight. This method should not be used in combination with the unweighted rotate, translate etc methods.

Multiple access to this method when neither the node nor the lights have moved will result in the same list being returned without recalculation. Can be useful when implementing Renderable::getLights.
Parameters:
radius Optional parameter to specify lights intersecting a given radius of this SceneNode's centre.

void Ogre::SceneNode::flipVisibility bool  cascade = true  )  [inherited]
 

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, inherited]
 

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, inherited]
 

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 ConstObjectIterator Ogre::SceneNode::getAttachedObjectIterator void   )  const [virtual, inherited]
 

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 ObjectIterator Ogre::SceneNode::getAttachedObjectIterator void   )  [virtual, inherited]
 

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.

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

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.

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.

Definition at line 138 of file OgreRenderable.h.

virtual unsigned short Ogre::Renderable::getNumWorldTransforms void   )  const [virtual, inherited]
 

Returns the number of world transform matrices this renderable requires.

Remarks:
When a renderable uses vertex blending, it uses multiple world matrices instead of a single one. Each vertex sent to the pipeline can reference one or more matrices in this list with given weights. If a renderable does not use vertex blending this method returns 1, which is the default for simplicity.

const Quaternion orientation,
Matrix4 destMatrix
[protected, inherited]
 

Internal method for building an inverse Matrix4 from orientation / scale / position.

Remarks:

const Vector3 scale,
const Quaternion orientation,
Matrix4 destMatrix
const [protected, inherited]
 

Internal method for building a Matrix4 from orientation / scale / position.

Remarks:
Transform is performed in the order rotate, scale, translation, i.e. translation is independent of orientation axes, scale does not affect size of translation, rotation and scaling are always centered on the origin.

virtual void Ogre::Node::needUpdate  )  [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.

virtual void Ogre::Node::pitch const Radian angle,
TransformSpace  relativeTo = TS_LOCAL
[virtual, inherited]
 

Rotate the node around the X-axis.

virtual void Ogre::Node::removeAllChildren void   )  [virtual, inherited]

virtual void Ogre::SceneNode::removeAndDestroyAllChildren void   )  [virtual, inherited]
 

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 unsigned short  index  )  [virtual, inherited]
 

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 void Ogre::SceneNode::removeAndDestroyChild const String name  )  [virtual, inherited]
 

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::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::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.

void Ogre::SceneNode::setAutoTracking bool  enabled,
SceneNode target = 0,
const Vector3 localDirectionVector = Vector3::NEGATIVE_UNIT_Z,
const Vector3 offset = Vector3::ZERO
[inherited]
 

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.

void Ogre::Renderable::setCustomParameter size_t  index,
const Vector4 value
[inherited]
 

Sets a custom parameter for this Renderable, which may be used to drive calculations for this specific Renderable, like GPU program parameters.

Remarks:
Calling this method simply associates a numeric index with a 4-dimensional value for this specific Renderable. This is most useful if the material which this Renderable uses a vertex or fragment program, and has an ACT_CUSTOM parameter entry. This parameter entry can refer to the index you specify as part of this call, thereby mapping a custom parameter for this renderable to a program parameter.
Parameters:
index The index with which to associate the value. Note that this does not have to start at 0, and can include gaps. It also has no direct correlation with a GPU program parameter index - the mapping between the two is performed by the ACT_CUSTOM entry, if that is used.
value The value to associate.

void Ogre::SceneNode::setDirection const Vector3 vec,
TransformSpace  relativeTo = TS_LOCAL,
const Vector3 localDirectionVector = Vector3::NEGATIVE_UNIT_Z
[inherited]
 

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

void Ogre::SceneNode::setDirection Real  x,
Real  y,
Real  z,
TransformSpace  relativeTo = TS_LOCAL,
const Vector3 localDirectionVector = Vector3::NEGATIVE_UNIT_Z
[inherited]
 

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

void Ogre::SceneNode::setFixedYawAxis bool  useFixed,
const Vector3 fixedAxis = Vector3::UNIT_Y
[inherited]
 

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::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 both the size and position 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 and position 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 and relative position). The default is to inherit as with other transforms.
Parameters:
inherit If true, this node's scale and position 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::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 both the size and position 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 and position 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 and relative position). The default is to inherit as with other transforms.
Note that like rotations, scalings are oriented around the node's origin.

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

i.e. the identity matrix.
x,y,z Translation components relative to the axes above.
relativeTo The space which this transform is relative to.

virtual void Ogre::Node::translate const Matrix3 axes,
const Vector3 move,
TransformSpace  relativeTo = TS_PARENT
[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
i.e. the identity matrix.

virtual bool Ogre::Renderable::useIdentityProjection void   )  const [virtual, inherited]
 

Returns whether or not to use an 'identity' projection.

Remarks:
Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not override this.

Reimplemented in Ogre::BorderRenderable, Ogre::OverlayElement, and Ogre::Rectangle2D.

Definition at line 114 of file OgreRenderable.h.

virtual bool Ogre::Renderable::useIdentityView void   )  const [virtual, inherited]
 

Returns whether or not to use an 'identity' projection.

Remarks:
Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not override this.
