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.

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.

See Node.

Implements Ogre::Node.

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

Reports the number of objects attached to this node.

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 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::detachObject ( unsigned short  index  )  [virtual]

Detaches the indexed object from this scene node.

Remarks:
Detaches by index, see the alternate version to detach by name. Object indexes may change as other objects are added / removed.

Detaches the named object from this node and returns a pointer to it.

virtual void Ogre::SceneNode::detachAllObjects ( void   )  [virtual]

Detaches all objects attached to this node.

virtual bool Ogre::SceneNode::isInSceneGraph ( void   )  const [virtual]

Determines whether this node is in the scene graph, i.e.

whether it's ultimate ancestor is the root scene node.

Definition at line 157 of file OgreSceneNode.h.

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 163 of file OgreSceneNode.h.

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::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 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 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.

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 241 of file OgreSceneNode.h.

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 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::showBoundingBox ( bool  bShow  )  [virtual]

Allows the showing of the node's bounding box.

Remarks:
Use this to show or hide the bounding box of the node.

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

Add the bounding box to the rendering queue.

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.

virtual SceneNode* Ogre::SceneNode::createChildSceneNode ( const Vector3 translate = Vector3::ZERO,
const Quaternion rotate = Quaternion::IDENTITY 
) [virtual]

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

Parameters:
translate Initial translation offset of child relative to parent

virtual SceneNode* Ogre::SceneNode::createChildSceneNode ( const String name,
const Vector3 translate = Vector3::ZERO,
const Quaternion rotate = Quaternion::IDENTITY 
) [virtual]

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 void Ogre::SceneNode::findLights ( LightList destList,
Real  radius 
) const [virtual]

Allows retrieval of the nearest lights to the centre of this SceneNode.

Remarks:
This method allows a list of lights, ordered by proximity to the centre of this SceneNode, to be retrieved. Can be useful when implementing MovableObject::queryLights and Renderable::getLights.
Note that only lights could be affecting the frustum will take into account, which cached in scene manager.
See also:
SceneManager::_getLightsAffectingFrustum

SceneManager::_populateLightList

Parameters:
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.

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::SceneNode::yaw ( const Radian angle,
TransformSpace  relativeTo = TS_LOCAL 
) [virtual]

Rotate the node around the Y-axis.

Reimplemented from Ogre::Node.

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::lookAt ( const Vector3 targetPoint,
TransformSpace  relativeTo,
const Vector3 localDirectionVector = Vector3::NEGATIVE_UNIT_Z 
) [virtual]

Points the local -Z direction of this node at a point in space.

Parameters:
targetPoint A vector specifying the look at point.
relativeTo The space in which the point resides
localDirectionVector The vector which normally describes the natural direction of the node, usually -Z

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.

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

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.

Returns a quaternion representing the nodes orientation.

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

Resets the nodes orientation (local axes as world axes, no rotation).

Remarks:
Orientations, unlike other transforms, are not always inherited by child nodes.

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 ( 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).

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.

See setInheritOrientation for more info.

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

Tells the node whether it should inherit scaling factors from it's parent node.

Remarks:
See setInheritScale for more info.

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.

const Vector3 translate = Vector3::ZERO,
const Quaternion rotate = Quaternion::IDENTITY

rotate Initial rotation relative to parent

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.

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

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.

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 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.

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.

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

Sets a listener for this Node.

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

Definition at line 618 of file OgreNode.h.

Definition at line 622 of file OgreNode.h.

const MaterialPtr& Ogre::Node::getMaterial ( void   )  const [virtual, inherited]

Overridden from Renderable.

Remarks:
This is only used if the SceneManager chooses to render the node. This option can be set for SceneNodes at SceneManager::setDisplaySceneNodes, and for entities based on skeletal models using Entity::setDisplayBones()

Implements Ogre::Renderable.

void Ogre::Node::getRenderOperation ( RenderOperation op  )  [virtual, inherited]

Overridden from Renderable.

Remarks:
This is only used if the SceneManager chooses to render the node. This option can be set for SceneNodes at SceneManager::setDisplaySceneNodes, and for entities based on skeletal models using Entity::setDisplaySkeleton()

Implements Ogre::Renderable.

void Ogre::Node::getWorldTransforms ( Matrix4 xform  )  const [virtual, inherited]

Overridden from Renderable.

Remarks:
This is only used if the SceneManager chooses to render the node. This option can be set for SceneNodes at SceneManager::setDisplaySceneNodes, and for entities based on skeletal models using Entity::setDisplaySkeleton()

Implements Ogre::Renderable.

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::resetToInitialState ( void   )  [virtual, inherited]

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

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

Implements Ogre::Renderable.

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 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::cancelUpdate ( Node child  )  [virtual, inherited]

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

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.

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

Process queued 'needUpdate' calls.

const LightList& Ogre::Node::getLights ( void   )  const [virtual, inherited]

Gets a list of lights, ordered relative to how close they are to this renderable.

Remarks:
Directional lights, which have no position, will always be first on this list.

Implements Ogre::Renderable.

Reimplemented in Ogre::TagPoint.

virtual Technique* Ogre::Renderable::getTechnique ( void   )  const [virtual, inherited]

Retrieves a pointer to the Material Technique this renderable object uses.

Remarks:
This is to allow Renderables to use a chosen Technique if they wish, otherwise they will use the best Technique available for the Material they are using.

Reimplemented in Ogre::InstancedGeometry::GeometryBucket, Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.

Definition at line 87 of file OgreRenderable.h.

virtual bool Ogre::Renderable::preRender ( SceneManager sm,
RenderSystem rsys 
) [virtual, inherited]

Called just prior to the Renderable being rendered.

Remarks:
OGRE is a queued renderer, so the actual render commands are executed at a later time than the point at which an object is discovered to be visible. This allows ordering & grouping of renders without the discovery process having to be aware of it. It also means OGRE uses declarative render information rather than immediate mode rendering - this is very useful in that certain effects and processes can automatically be applied to a wide range of scenes, but the downside is that special cases are more difficult to handle, because there is not the declared state to cope with it.
This method allows a Renderable to do something special at the actual point of rendering if it wishes to. When this method is called, all the material render state as declared by this Renderable has already been set, all that is left to do is to bind the buffers and perform the render. The Renderable may modify render state itself if it wants to (and restore it in the postRender call) before the automated render happens, or by returning 'false' from this method can actually suppress the automatic render and perform one of its own.
Returns:
true if the automatic render should proceed, false to skip it on the assumption that the Renderable has done it manually.

Definition at line 116 of file OgreRenderable.h.

virtual void Ogre::Renderable::postRender ( SceneManager sm,
RenderSystem rsys 
) [virtual, inherited]

Called immediately after the Renderable has been rendered.

Definition at line 119 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.

Reimplemented in Ogre::BorderRenderable, Ogre::InstancedGeometry::GeometryBucket, and Ogre::SubEntity.

Definition at line 143 of file OgreRenderable.h.

void Ogre::Renderable::setUseIdentityProjection ( bool  useIdentityProjection  )  [inherited]

Sets 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 change this. The default is false.

Sets whether or not to use an 'identity' view.

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 change this. The default is false.

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

Method which reports whether this renderable would normally cast a shadow.

Remarks:
Subclasses should override this if they could have been used to generate a shadow.

Reimplemented in Ogre::InstancedGeometry::GeometryBucket, Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.

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.

Definition at line 231 of file OgreRenderable.h.

const Vector4& Ogre::Renderable::getCustomParameter ( size_t  index  )  const [inherited]

Gets the custom value associated with this Renderable at the given index.

Parameters:
@see setCustomParaemter for full details.

References Ogre::Exception::ERR_ITEM_NOT_FOUND, and OGRE_EXCEPT.

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.
