Detailed Description

The details of a topological region which is the highest level of partitioning for this class.

Remarks
The size & shape of regions entirely depends on the SceneManager specific implementation. It is a MovableObject since it will be attached to a node based on the local centre - in practice it won't actually move (although in theory it could).

void Ogre::StaticGeometry::Region::assign ( QueuedSubMesh qmesh)

Assign a queued mesh to this region, read for final build.

◆ build()

void Ogre::StaticGeometry::Region::build ( bool  stencilShadows)

inline

Get the region ID of this region.

◆ getCentre()

const Vector3& Ogre::StaticGeometry::Region::getCentre ( void  ) const
inline

Get the centre point of the region.

◆ getMovableType()

const String& Ogre::StaticGeometry::Region::getMovableType ( void  ) const
virtual

Returns the type name of this object.

Implements Ogre::MovableObject.

◆ _notifyCurrentCamera()

void Ogre::StaticGeometry::Region::_notifyCurrentCamera ( Camera cam)
virtual

Internal method to notify the object of the camera to be used for the next rendering operation.

Remarks
Certain objects may want to do specific processing based on the camera position. This method notifies them in case they wish to do this.

Reimplemented from Ogre::MovableObject.

◆ getBoundingBox()

const AxisAlignedBox& Ogre::StaticGeometry::Region::getBoundingBox ( void  ) const
virtual

Retrieves the local axis-aligned bounding box for this object.

Remarks
This bounding box is in local coordinates.

Implements Ogre::MovableObject.

◆ getBoundingRadius()

Real Ogre::StaticGeometry::Region::getBoundingRadius ( void  ) const
virtual

Retrieves the radius of the origin-centered bounding sphere for this object.

Implements Ogre::MovableObject.

◆ _updateRenderQueue()

void Ogre::StaticGeometry::Region::_updateRenderQueue ( RenderQueue queue)
virtual

Internal method by which the movable object must add Renderable subclass instances to the rendering queue.

Remarks
The engine will call this method when this object is to be rendered. The object must then create one or more Renderable subclass instances which it places on the passed in Queue for rendering.

Implements Ogre::MovableObject.

◆ visitRenderables()

void Ogre::StaticGeometry::Region::visitRenderables ( Renderable::Visitor visitor,
bool  debugRenderables = false 
)
virtual

Method to allow a caller to abstractly iterate over the Renderable instances that this MovableObject will add to the render queue when asked, if any.

Parameters
visitorPointer to a class implementing the Renderable::Visitor interface which will be called back for each Renderable which will be queued. Bear in mind that the state of the Renderable instances may not be finalised depending on when you call this.
debugRenderablesIf false, only regular renderables will be visited (those for normal display). If true, debug renderables will be included too.

Implements Ogre::MovableObject.

◆ isVisible()

bool Ogre::StaticGeometry::Region::isVisible ( void  ) const
virtual

Returns whether or not this object is supposed to be visible or not.

Remarks
Takes into account both upper rendering distance and visible flag.

Reimplemented from Ogre::MovableObject.

◆ getTypeFlags()

uint32 Ogre::StaticGeometry::Region::getTypeFlags ( void  ) const
virtual

Get the 'type flags' for this MovableObject.

Remarks
A type flag identifies the type of the MovableObject as a bitpattern. This is used for categorical inclusion / exclusion in SceneQuery objects. By default, this method returns all ones for objects not created by a MovableObjectFactory (hence always including them); otherwise it returns the value assigned to the MovableObjectFactory. Custom objects which don't use MovableObjectFactory will need to override this if they want to be included in queries.

Reimplemented from Ogre::MovableObject.

◆ getLODIterator()

LODIterator Ogre::StaticGeometry::Region::getLODIterator ( void  )

◆ getLODBuckets()

const LODBucketList& Ogre::StaticGeometry::Region::getLODBuckets ( ) const

const Light light,
HardwareIndexBufferSharedPtr indexBuffer,
size_t *  indexBufferUsedSize,
bool  extrudeVertices,
Real  extrusionDist,
unsigned long  flags = 0 
)
overridevirtual

Define a default implementation of method from ShadowCaster which implements no shadows.

Reimplemented from Ogre::MovableObject.

◆ getEdgeList()

EdgeData* Ogre::StaticGeometry::Region::getEdgeList ( void  )
overridevirtual

Returns details of the edges which might be used to determine a silhouette.

Reimplemented from Ogre::MovableObject.

◆ _releaseManualHardwareResources()

void Ogre::StaticGeometry::Region::_releaseManualHardwareResources ( )
overridevirtual

Notifies the movable object that hardware resources were lost.

Remarks
Called automatically by RenderSystem if hardware resources were lost and can not be restored using some internal mechanism. Among affected resources are nested shadow renderables, ManualObjects, etc.

Reimplemented from Ogre::MovableObject.

◆ _restoreManualHardwareResources()

void Ogre::StaticGeometry::Region::_restoreManualHardwareResources ( )
overridevirtual

Notifies the movable object that hardware resources should be restored.

Remarks
Called automatically by RenderSystem if hardware resources were lost and can not be restored using some internal mechanism. Among affected resources are nested shadow renderables, ManualObjects, etc.
