## Detailed Description

Subclass of BillboardChain which automatically leaves a trail behind one or more Node instances.

Remarks:
  An instance of this class will watch one or more Node instances, and automatically generate a trail behind them as they move. Because this class can monitor multiple modes, it generates its own geometry in world space and thus, even though it has to be attached to a SceneNode to be visible, changing the position of the scene node it is attached to makes no difference to the geometry rendered.

  The 'head' element grows smoothly in size until it reaches the required size, then a new element is added. If the segment is full, the tail element shrinks by the same proportion as the head grows before disappearing.

  Elements can be faded out on a time basis, either by altering their colour or altering their alpha. The width can also alter over time.

  'v' texture coordinates are fixed at 0.0 if used, meaning that you can use a 1D texture to 'smear' a colour pattern along the ribbon if you wish. The 'u' coordinates are by default (0.0, 1.0), but you can alter this using setOtherTexCoordRange if you wish.

|  | const Element & | billboardChainElement |
| ) |  |  | `[virtual, inherited]`

void Ogre::BillboardChain::_notifyCurrentCamera | ( | Camera * | cam | ) | `[virtual, inherited]`

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.

Real Ogre::BillboardChain::getSquaredViewDepth | ( | const Camera * | cam | ) | const`[virtual, inherited]`

Returns the camera-relative squared depth of this renderable.

Remarks:
  Used to sort transparent objects. Squared depth is used rather than actual depth to avoid having to perform a square root on the result.

Implements Ogre::Renderable.

Real Ogre::BillboardChain::getBoundingRadius | ( | void |  | ) | const`[virtual, inherited]`

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

Implements Ogre::MovableObject.

const AxisAlignedBox& Ogre::BillboardChain::getBoundingBox | ( | void |  | ) | const`[virtual, inherited]`

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

Implements Ogre::MovableObject.

void Ogre::BillboardChain::getRenderOperation | ( | RenderOperation & | op | ) | `[virtual, inherited]`

Gets the render operation required to send this object to the frame buffer.

Implements Ogre::Renderable.

void Ogre::BillboardChain::getWorldTransforms | ( | Matrix4 * | xform | ) | const`[virtual, inherited]`

Gets the world transform matrix / matrices for this renderable object.

Remarks:
  If the object has any derived transforms, these are expected to be up to date as long as all the SceneNode structures have been updated before this is called.

  This method will populate xform with 1 matrix if it does not use vertex blending. If it does use vertex blending it will fill the passed in pointer with an array of matrices, the length being the value returned from getNumWorldTransforms.

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

See also:
  Matrix4::isAffine.

Implements Ogre::Renderable.

const Quaternion& Ogre::BillboardChain::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::BillboardChain::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.

const LightList& Ogre::BillboardChain::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.

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 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]`

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 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 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]`

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

Definition at line 342 of file OgreMovableObject.h.

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

Returns the query flags relevant for this object.

Definition at line 345 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 349 of file OgreMovableObject.h.

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

Get the default query flags for all future MovableObject instances.

Definition at line 353 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 362 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 366 of file OgreMovableObject.h.

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

Definition at line 370 of file OgreMovableObject.h.

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

Returns the visibility flags relevant for this object.

Definition at line 373 of file OgreMovableObject.h.

Set the default visibility flags for all future MovableObject instances.

Definition at line 377 of file OgreMovableObject.h.

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

Get the default visibility flags for all future MovableObject instances.

Definition at line 381 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 388 of file OgreMovableObject.h.

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.

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.

Definition at line 415 of file OgreMovableObject.h.

bool Ogre::MovableObject::hasEdgeList | ( | 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.

Definition at line 417 of file OgreMovableObject.h.

ShadowRenderableListIterator Ogre::MovableObject::getShadowVolumeRenderableIterator | ( | ShadowTechnique | shadowTechnique,
|  | const Light * | light,
|  | HardwareIndexBufferSharedPtr * | indexBuffer,
|  | bool | extrudeVertices,
|  | Real | extrusionDist,
|  | unsigned long | flags = `0` |
| ) |  |  | `[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.

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]`

Returns whether shadow casting is enabled for this object.

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.

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::Light, Ogre::ParticleSystem, and Ogre::StaticGeometry::Region.

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

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.

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.

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.

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.

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.

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.

virtual bool Ogre::MovableObject::Listener::objectRendering | ( | const MovableObject * | ,
|  | const Camera * |  |
| ) |  |  | `[virtual, inherited]`

Called when the movable object of the camera to be used for rendering.

Returns:
  true if allows queue for rendering, false otherwise.

Definition at line 76 of file OgreMovableObject.h.

virtual const LightList* Ogre::MovableObject::Listener::objectQueryLights | ( | const MovableObject * |  | ) | `[virtual, inherited]`

Called when the movable object needs to query a light list.

Remarks:
  If you want to customize light finding for this object, you should override this method and hook into MovableObject via MovableObject::setListener. Be aware that the default method caches results within a frame to prevent unnecessary recalculation, so if you override this you should provide your own cacheing to maintain performance.

Note:
  If you use texture shadows, there is an additional restriction - since the lights which should have shadow textures rendered for them are determined based on the entire frustum, and not per-object, it is important that the lights returned at the start of this list (up to the number of shadow textures available) are the same lights that were used to generate the shadow textures, and they are in the same order (particularly for additive effects).

Returns:
  A pointer to a light list if you populated the light list yourself, or NULL to fall back on the default finding process.
