Detailed Description

Allows the rendering of a chain of connected billboards.

Remarks:
A billboard chain operates much like a traditional billboard, i.e. its segments always face the camera; the difference being that instead of a set of disconnected quads, the elements in this class are connected together in a chain which must always stay in a continuous strip. This kind of effect is useful for creating effects such as trails, beams, lightning effects, etc.
A single instance of this class can actually render multiple separate chain segments in a single render operation, provided they all use the same material. To clarify the terminology: a 'segment' is a separate sub-part of the chain with its own start and end (called the 'head' and the 'tail'. An 'element' is a single position / colour / texcoord entry in a segment. You can add items to the head of a chain, and remove them from the tail, very efficiently. Each segment has a max size, and if adding an element to the segment would exceed this size, the tail element is automatically removed and re-used as the new item on the head.
This class has no auto-updating features to do things like alter the colour of the elements or to automatically add / remove elements over time - you have to do all this yourself as a user of the class. Subclasses can however be used to provide this kind of behaviour automatically.

Internal Ogre never supports non-affine matrix for world transform matrix/matrices, the behavior is undefined if returns non-affine matrix here.

Matrix4::isAffine.

Implements Ogre::Renderable.

const LightList& Ogre::BillboardChain::getLights ( void   )  const [virtual]

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.

void Ogre::BillboardChain::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:
visitor Pointer 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.
debugRenderables If false, only regular renderables will be visited (those for normal display). If true, debug renderables will be included too.

Implements Ogre::MovableObject.

virtual const String& Ogre::MovableObject::getName ( void   )  const [virtual, inherited]

Returns the name of this object.

Reimplemented in Ogre::Camera.

Definition at line 178 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 void Ogre::MovableObject::detatchFromParent ( void   )  [virtual, inherited]

Detaches an object from a parent SceneNode or TagPoint, if attached.

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

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

Internal method called to notify the object that it has been moved.

Reimplemented in Ogre::Light.

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

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 visibility 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 visibility 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 bool Ogre::MovableObject::isVisible ( void   )  const [virtual, inherited]

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 in Ogre::InstancedGeometry::BatchInstance, and Ogre::StaticGeometry::Region.

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 280 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 286 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 294 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 298 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 310 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 314 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 342 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 346 of file OgreMovableObject.h.

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

As setQueryFlags, except the flags passed as parameters are removed from the existing flags on this object.

Definition at line 350 of file OgreMovableObject.h.

virtual uint32 Ogre::MovableObject::getQueryFlags ( void   )  const [virtual, inherited]

Returns the query flags relevant for this object.

Definition at line 353 of file OgreMovableObject.h.

static void Ogre::MovableObject::setDefaultQueryFlags ( uint32  flags  )  [static, inherited]

Set the default query flags for all future MovableObject instances.

Definition at line 357 of file OgreMovableObject.h.

static uint32 Ogre::MovableObject::getDefaultQueryFlags (  )  [static, inherited]

Get the default query flags for all future MovableObject instances.

Definition at line 361 of file OgreMovableObject.h.

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

Sets the visiblity flags for this object.

Remarks:
As well as a simple true/false value for visibility (as seen in setVisible), you can also set visiblity flags which when 'and'ed with the SceneManager's visibility mask can also make an object invisible.

Definition at line 370 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::addVisibilityFlags ( uint32  flags  )  [virtual, inherited]

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

Definition at line 374 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::removeVisibilityFlags ( uint32  flags  )  [virtual, inherited]

As setVisibilityFlags, except the flags passed as parameters are removed from the existing flags on this object.

Definition at line 378 of file OgreMovableObject.h.

virtual uint32 Ogre::MovableObject::getVisibilityFlags ( void   )  const [virtual, inherited]

static uint32 Ogre::MovableObject::getDefaultVisibilityFlags (  )  [static, inherited]

Get the default visibility flags for all future MovableObject instances.

Definition at line 389 of file OgreMovableObject.h.

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

Sets a listener for this object.

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

Definition at line 396 of file OgreMovableObject.h.

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

Gets the current listener for this object.

Definition at line 400 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.

virtual LightList* Ogre::MovableObject::_getLightList (  )  [virtual, inherited]

Returns a pointer to the current list of lights for this object.

Remarks:
You should not modify this list outside of MovableObject::Listener::objectQueryLights (say if you want to use it to implement this method, and use the pointer as a return value) and for reading it's only accurate as at the last frame.

Definition at line 428 of file OgreMovableObject.h.

EdgeData* Ogre::MovableObject::getEdgeList ( void   )  [virtual, inherited]

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

Implements Ogre::ShadowCaster.

Reimplemented in Ogre::Entity, Ogre::ManualObject, and Ogre::StaticGeometry::Region.

Implements Ogre::ShadowCaster.

Reimplemented in Ogre::Entity, Ogre::ManualObject, and Ogre::StaticGeometry::Region.

const Light light,
HardwareIndexBufferSharedPtr indexBuffer,

) [virtual, inherited]

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

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 456 of file OgreMovableObject.h.

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

Returns whether shadow casting is enabled for this object.

Implements Ogre::ShadowCaster.

Definition at line 458 of file OgreMovableObject.h.

bool Ogre::MovableObject::getReceivesShadows (  )  [inherited]

Returns whether the Material of any Renderable that this MovableObject will add to the render queue will receive shadows.

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

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

Implements Ogre::ShadowCaster.

virtual uint32 Ogre::MovableObject::getTypeFlags ( void   )  const [virtual, inherited]

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 in Ogre::BillboardSet, Ogre::Entity, Ogre::Frustum, Ogre::Light, Ogre::ParticleSystem, and Ogre::StaticGeometry::Region.

virtual void Ogre::MovableObject::setDebugDisplayEnabled ( bool  enabled  )  [virtual, inherited]

Sets whether or not the debug display of this object is enabled.

Remarks:
Some objects aren't visible themselves but it can be useful to display a debug representation of them. Or, objects may have an additional debug display on top of their regular display. This option enables / disables that debug display. Objects that are not visible never display debug geometry regardless of this setting.

Definition at line 500 of file OgreMovableObject.h.

virtual bool Ogre::MovableObject::isDebugDisplayEnabled ( void   )  const [virtual, inherited]

Gets whether debug display of this object is enabled.

Definition at line 502 of file OgreMovableObject.h.

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 homogeneous (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, i.e. 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 method 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

virtual const String& Ogre::AnimableObject::getAnimableDictionaryName ( void   )  const [protected, virtual, inherited]

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.
See also:
Renderable::getUseIdentityProjection

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.

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.

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

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.
