## 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.

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

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
  | rotate | Initial rotation relative to parent

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

Creates a new named SceneNode as a child of this node.

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.

|  | bool | cascade = `true` |
| ) |  |  | `[virtual]`

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

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

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:
  Orientatings, unlike other transforms, are not always inherited by child nodes. Whether or not orientatings 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.

The default is to inherit as with other transforms.

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

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

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

Remarks:

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.

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::setScale | ( | Real | x,
|  | Real | y,
|  | Real | z |
| ) |  |  | `[virtual, inherited]`

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

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

Remarks:
  Orientatings, unlike other transforms, are not always inherited by child nodes. Whether or not orientatings affect the orientation of the child nodes depends on the setInheritOrientation option of the child.

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,

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

Scales the node, combining it's current scale with the passed in scaling factor.

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.

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.

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

Gets the worldspace orientation of this renderable; this is used in order to more efficiently update parameters to vertex & fragment programs, since inverting Quaterion and Vector in order to derive object-space positions / directions for cameras and lights is much more efficient than inverting a complete 4x4 matrix, and also eliminates problems introduced by scaling.

Implements Ogre::Renderable.

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

Gets the worldspace position of this renderable; this is used in order to more efficiently update parameters to vertex & fragment programs, since inverting Quaterion and Vector in order to derive object-space positions / directions for cameras and lights is much more efficient than inverting a complete 4x4 matrix, and also eliminates problems introduced by scaling.

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]`

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.

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 73 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 111 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.

  Renderable::getUseIdentityProjection

Definition at line 122 of file OgreRenderable.h.

bool Ogre::Renderable::getUseIdentityProjection | ( | void |  | ) | const`[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 change this.

Definition at line 136 of file OgreRenderable.h.

void Ogre::Renderable::setUseIdentityView | ( | bool | useIdentityView | ) | `[inherited]`

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.

See also:
  Renderable::getUseIdentityView

Definition at line 147 of file OgreRenderable.h.

bool Ogre::Renderable::getUseIdentityView | ( | void |  | ) | const`[inherited]`

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

Remarks:

virtual bool Ogre::Renderable::getNormaliseNormals | ( | void |  | ) | const`[virtual, inherited]`

Reimplemented in Ogre::SubEntity.

Definition at line 171 of file OgreRenderable.h.

virtual const PlaneList& Ogre::Renderable::getClipPlanes | ( |  | ) | const`[virtual, inherited]`

Definition at line 179 of file OgreRenderable.h.

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.

Definition at line 187 of file OgreRenderable.h.

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 204 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.

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::SubEntity.

virtual void Ogre::Renderable::setPolygonModeOverrideable | ( | bool | override | ) | `[virtual, inherited]`

Sets whether this renderable's chosen detail level can be overridden (downgraded) by the camera setting.

Parameters:

  | override | true means that a lower camera detail will override this renderables detail level, false means it won't.

virtual bool Ogre::Renderable::getPolygonModeOverrideable | ( | void |  | ) | const`[virtual, inherited]`
