## 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).

const String& Ogre::StaticGeometry::Region::getMovableType | ( | void |  | ) | const`[virtual]`

Returns the type name of this object.

Implements Ogre::MovableObject.

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 incase they wish to do this.

Reimplemented from Ogre::MovableObject.

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.

Real Ogre::StaticGeometry::Region::getBoundingRadius | ( | void |  | ) | const`[virtual]`

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

Implements Ogre::MovableObject.

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.

bool Ogre::StaticGeometry::Region::isVisible | ( | void |  | ) | const`[virtual]`

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

Remarks:

Reimplemented from Ogre::MovableObject.

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.

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

Get an iterator over the LODs in this region.

ShadowRenderableListIterator Ogre::StaticGeometry::Region::getShadowVolumeRenderableIterator | ( | ShadowTechnique | shadowTechnique,
|  | const Light * | light,

|  | bool | extrudeVertices,
|  | Real | extrusionDistance,
|  | unsigned long | flags = `0` |
| ) |  |  | `[virtual]`

Gets an iterator over the renderables required to render the shadow volume.

Remarks:
  Shadowable geometry should ideally be designed such that there is only one ShadowRenderable required to render the the shadow; however this is not a necessary limitation and it can be exceeded if required.

Parameters:

  | shadowTechnique | The technique being used to generate the shadow
  | light | The light to generate the shadow from
  | indexBuffer | The index buffer to build the renderables into, the current contents are assumed to be disposable.
  | extrudeVertices | If true, this means this class should extrude the vertices of the back of the volume in software. If false, it will not be done (a vertex program is assumed).
  | extrusionDistance | The distance to extrude the shadow volume

Dump contents for diagnostics.

virtual void Ogre::MovableObject::_notifyCreator | ( | MovableObjectFactory * | fact | ) | `[virtual, inherited]`

Reimplemented in Ogre::Camera.

Definition at line 173 of file OgreMovableObject.h.

virtual Node* Ogre::MovableObject::getParentNode | ( | void |  | ) | const`[virtual, inherited]`

Returns the node to which this object is attached.

Remarks:
  A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. Both are Node subclasses so this method will return either.

virtual SceneNode* Ogre::MovableObject::getParentSceneNode | ( | void |  | ) | const`[virtual, inherited]`

Returns the scene node to which this object is attached.

Remarks:
  A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. This method will return the scene node of the parent entity if the latter is true.

virtual void Ogre::MovableObject::_notifyAttached | ( | Node * | parent,
|  | bool | isTagPoint = `false` |
| ) |  |  | `[virtual, inherited]`

Internal method called to notify the object that it has been attached to a node.

Reimplemented in Ogre::Entity, Ogre::Light, and Ogre::ParticleSystem.

virtual bool Ogre::MovableObject::isAttached | ( | void |  | ) | const`[virtual, inherited]`

Returns true if this object is attached to a SceneNode or TagPoint.

virtual bool Ogre::MovableObject::isInScene | ( | void |  | ) | const`[virtual, inherited]`

Returns true if this object is attached to a SceneNode or TagPoint, and this SceneNode / TagPoint is currently in an active part of the scene graph.

virtual void Ogre::MovableObject::_notifyMoved | ( | void |  | ) | `[virtual, inherited]`

Reimplemented in Ogre::Light.

virtual const AxisAlignedBox& Ogre::MovableObject::getWorldBoundingBox | ( | bool | derive = `false` | ) | const`[virtual, inherited]`

Retrieves the axis-aligned bounding box for this object in world coordinates.

Implements Ogre::ShadowCaster.

Reimplemented in Ogre::Entity.

virtual const Sphere& Ogre::MovableObject::getWorldBoundingSphere | ( | bool | derive = `false` | ) | const`[virtual, inherited]`

Retrieves the worldspace bounding sphere for this object.

Reimplemented in Ogre::Entity.

virtual void Ogre::MovableObject::setVisible | ( | bool | visible | ) | `[virtual, inherited]`

Tells this object whether to be visible or not, if it has a renderable component.

Note:
  An alternative approach of making an object invisible is to detach it from it's SceneNode, or to remove the SceneNode entirely. Detaching a node means that structurally the scene graph changes. Once this change has taken place, the objects / nodes that have been removed have less overhead to the visbility detection pass than simply making the object invisible, so if you do this and leave the objects out of the tree for a long time, it's faster. However, the act of detaching / reattaching nodes is in itself more expensive than setting an object visibility flag, since in the latter case structural changes are not made. Therefore, small or frequent visbility changes are best done using this method; large or more longer term changes are best done by detaching.

Reimplemented in Ogre::Light.

virtual bool Ogre::MovableObject::getVisible | ( | void |  | ) | const`[virtual, inherited]`

Gets this object whether to be visible or not, if it has a renderable component.

Remarks:
  Returns the value set by MovableObject::setVisible only.

virtual void Ogre::MovableObject::setRenderingDistance | ( | Real | dist | ) | `[virtual, inherited]`

Sets the distance at which the object is no longer rendered.

Parameters:

  | dist | Distance beyond which the object will not be rendered (the default is 0, which means objects are always rendered).

Definition at line 272 of file OgreMovableObject.h.

virtual Real Ogre::MovableObject::getRenderingDistance | ( | void |  | ) | const`[virtual, inherited]`

Gets the distance at which batches are no longer rendered.

Definition at line 278 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setUserObject | ( | UserDefinedObject * | obj | ) | `[virtual, inherited]`

Call this to associate your own custom user object instance with this MovableObject.

Remarks:
  By simply making your game / application object a subclass of UserDefinedObject, you can establish a link between an OGRE instance of MovableObject and your own application classes. Call this method to establish the link.

Definition at line 286 of file OgreMovableObject.h.

virtual UserDefinedObject* Ogre::MovableObject::getUserObject | ( | void |  | ) | `[virtual, inherited]`

Retrieves a pointer to a custom application object associated with this movable by an earlier call to setUserObject.

Definition at line 290 of file OgreMovableObject.h.

References Ogre::any_cast().

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

Sets any kind of user value on this object.

Remarks:
  This method allows you to associate any user value you like with this MovableObject. This can be a pointer back to one of your own classes for instance.

Note:
  This value is shared with setUserObject so don't use both!

Definition at line 302 of file OgreMovableObject.h.

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

Retrieves the custom user value associated with this object.

Definition at line 306 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setRenderQueueGroup | ( | uint8 | queueID | ) | `[virtual, inherited]`

Sets the render queue group this entity will be rendered through.

Remarks:
  Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to the default queue (RenderQueue::getDefaultQueueGroup), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.

  See RenderQueue for more details.

Parameters:

  | queueID | Enumerated value of the queue group to use.

Reimplemented in Ogre::Entity, and Ogre::ParticleSystem.

virtual uint8 Ogre::MovableObject::getRenderQueueGroup | ( | void |  | ) | const`[virtual, inherited]`

Gets the queue group for this entity, see setRenderQueueGroup for full details.

virtual const Matrix4& Ogre::MovableObject::_getParentNodeFullTransform | ( | void |  | ) | const`[virtual, inherited]`

return the full transformation of the parent sceneNode or the attachingPoint node

virtual void Ogre::MovableObject::setQueryFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

Sets the query flags for this object.

Remarks:
  When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

Definition at line 334 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::addQueryFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

As setQueryFlags, except the flags passed as parameters are appended to the existing flags on this object.

Definition at line 338 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::removeQueryFlags | ( | unsigned long | flags | ) | `[virtual, inherited]`

Definition at line 353 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisibilityFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

virtual Listener* Ogre::MovableObject::getListener | ( | void |  | ) | const`[virtual, inherited]`

Gets the current listener for this object.

Definition at line 392 of file OgreMovableObject.h.

virtual const LightList& Ogre::MovableObject::queryLights | ( | void |  | ) | const`[virtual, inherited]`

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

Remarks:
  By default, this method gives the listener a chance to populate light list first, if there is no listener or Listener::objectQueryLights returns NULL, it'll query the light list from parent entity if it is present, or returns SceneNode::findLights if it has parent scene node, otherwise it just returns an empty list.

  The object internally caches the light list, so it will recalculate it only when object is moved, or lights that affect the frustum have been changed (

See also:
  SceneManager::_getLightsDirtyCounter), but if listener exists, it will be called each time, so the listener should implement their own cache mechanism to optimise performance.

  This method can be useful when implementing Renderable::getLights in case the renderable is a part of the movable.

Returns:
  The list of lights use to lighting this object.

const AxisAlignedBox& Ogre::MovableObject::getLightCapBounds | ( | void |  | ) | const`[virtual, inherited]`

Overridden member from ShadowCaster.

Implements Ogre::ShadowCaster.

const AxisAlignedBox& Ogre::MovableObject::getDarkCapBounds | ( | const Light & | light,
|  | Real | dirLightExtrusionDist |
| ) |  |  | const`[virtual, inherited]`

Overridden member from ShadowCaster.

Implements Ogre::ShadowCaster.

void Ogre::MovableObject::setCastShadows | ( | bool | enabled | ) | `[inherited]`

Sets whether or not this object will cast shadows.

Remarks:
  This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.

Note:
  This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

Definition at line 440 of file OgreMovableObject.h.

bool Ogre::MovableObject::getCastShadows | ( | void |  | ) | const`[virtual, inherited]`

Implements Ogre::ShadowCaster.

Definition at line 442 of file OgreMovableObject.h.

Real Ogre::MovableObject::getPointExtrusionDistance | ( | const Light * | l | ) | const`[virtual, inherited]`

Get the distance to extrude for a point/spot light.

Implements Ogre::ShadowCaster.

static void Ogre::ShadowCaster::extrudeVertices | ( | const HardwareVertexBufferSharedPtr & | vertexBuffer,
|  | size_t | originalVertexCount,
|  | const Vector4 & | lightPos,
|  | Real | extrudeDist |
| ) |  |  | `[static, inherited]`

Utility method for extruding vertices based on a light.

Remarks:
  Unfortunately, because D3D cannot handle homogenous (4D) position coordinates in the fixed-function pipeline (GL can, but we have to be cross-API), when we extrude in software we cannot extrude to infinity the way we do in the vertex program (by setting w to 0.0f). Therefore we extrude by a fixed distance, which may cause some problems with larger scenes. Luckily better hardware (ie vertex programs) can fix this.

Parameters:

  | vertexBuffer | The vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
  | originalVertexCount | The count of the original number of vertices, ie the number in the mesh, not counting the doubling which has already been done (by VertexData::prepareForShadowVolume) to provide the extruded area of the buffer.
  | lightPos | 4D light position in object space, when w=0.0f this represents a directional light
  | extrudeDist | The distance to extrude

Real Ogre::ShadowCaster::getExtrusionDistance | ( | const Vector3 & | objectPos,
|  | const Light * | light |
| ) |  |  | const`[protected, inherited]`

Helper moethod for calculating extrusion distance.

virtual void Ogre::ShadowCaster::updateEdgeListLightFacing | ( | EdgeData * | edgeData,
|  | const Vector4 & | lightPos |
| ) |  |  | `[protected, virtual, inherited]`

Tells the caster to perform the tasks necessary to update the edge data's light listing.

Can be overridden if the subclass needs to do additional things.

Parameters:

  | edgeData | The edge information to update
  | lightPos | 4D vector representing the light, a directional light has w=0.0

virtual void Ogre::ShadowCaster::generateShadowVolume | ( | EdgeData * | edgeData,
|  | const HardwareIndexBufferSharedPtr & | indexBuffer,
|  | const Light * | light,
|  | ShadowRenderableList & | shadowRenderables,
|  | unsigned long | flags |
| ) |  |  | `[protected, virtual, inherited]`

Generates the indexes required to render a shadow volume into the index buffer which is passed in, and updates shadow renderables to use it.

Parameters:

  | edgeData | The edge information to use
  | indexBuffer | The buffer into which to write data into; current contents are assumed to be discardable.
  | light | The light, mainly for type info as silhouette calculations should already have been done in updateEdgeListLightFacing
  | shadowRenderables | A list of shadow renderables which has already been constructed but will need populating with details of the index ranges to be used.
  | flags | Additional controller flags, see ShadowRenderableFlags

virtual void Ogre::ShadowCaster::extrudeBounds | ( | AxisAlignedBox & | box,
|  | const Vector4 & | lightPos,
|  | Real | extrudeDist |
| ) |  |  | const`[protected, virtual, inherited]`

Utility method for extruding a bounding box.

Parameters:

  | box | Original bounding box, will be updated in-place
  | lightPos | 4D light position in object space, when w=0.0f this represents a directional light
  | extrudeDist | The distance to extrude
