## Detailed Description

Representation of a dynamic light source in the scene.

Remarks:
  Lights are added to the scene like any other object. They contain various parameters like type, position, attenuation (how light intensity fades with distance), colour etc.

  The defaults when a light is created is pure white diffues light, with no attenuation (does not decrease with distance) and a range of 1000 world units.

  Lights are created by using the SceneManager::createLight method. They can subsequently be added to a SceneNode if required to allow them to move relative to a node in the scene. A light attached to a SceneNode is assumed to havea base position of (0,0,0) and a direction of (0,0,1) before modification by the SceneNode's own orientation. If not attached to a SceneNode, the light's position and direction is as set using setPosition and setDirection.

  Remember also that dynamic lights rely on modifying the colour of vertices based on the position of the light compared to an object's vertex normals. Dynamic lighting will only look good if the object being lit has a fair level of tesselation and the normals are properly set. This is particularly true for the spotlight which will only look right on highly tesselated models. In the future OGRE may be extended for certain scene types so an alternative to the standard dynamic lighting may be used, such as dynamic lightmaps.

## Member Enumeration Documentation

enum Ogre::Light::LightTypes

  | Defines the type of light. Enumeration values:
  LT_POINT | Point light sources give off light equally in all directions, so require only position not direction.
  LT_DIRECTIONAL | Directional lights simulate parallel light beams from a distant source, hence have direction but no position.
  LT_SPOTLIGHT | Spotlights simulate a cone of light from a source so require position and direction, plus extra values for falloff.

  | 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

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

  | 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

const String& Ogre::Light::getAnimableDictionaryName | ( | void |  | ) | const`[protected, virtual]`

| Gets the details of this light as a 4D vector. Remarks: Getting details of a light as a 4D vector can be useful for doing general calculations between different light types; for example the vector can represent both position lights (w=1.0f) and directional lights (w=0.0f) and be used in the same calculations.

|  | const Light * | light,
|  | HardwareIndexBufferSharedPtr * | indexBuffer,
|  | bool | extrudeVertices,
|  | Real | extrusionDist,
|  | unsigned long | flags = `0`
| ) | `[virtual, inherited]`

void Ogre::Light::initialiseAnimableDictionary | ( | StringVector & | vec | ) | const`[protected, virtual]`

| Reimplemented from Ogre::AnimableObject.

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

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

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 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 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 370 of file OgreMovableObject.h.

void Ogre::Light::resetCustomShadowCameraSetup | ( | void |  | ) |

| Reset the shadow camera setup to the default. See also: ShadowCameraSetup

void Ogre::Light::setAttenuation | ( | Real | range,
|  | Real | constant,
|  | Real | linear,
|  | Real | quadratic
| ) |

  | Sets the attenuation parameters of the light source ie how it diminishes with distance. Remarks: Lights normally get fainter the further they are away. Also, each light is given a maximum range beyond which it cannot affect any objects. Light attentuation is not applicable to directional lights since they have an infinite range and constant intensity. This follows a standard attenuation approach - see any good 3D text for the details of what they mean since i don't have room here! Parameters:
  | range | The absolute upper range of the light in world units
  | constant | The constant factor in the attenuation formula: 1.0 means never attenuate, 0.0 is complete attenuation
  | linear | The linear factor in the attenuation formula: 1 means attenuate evenly over the distance
  | quadratic | The quadratic factor in the attenuation formula: adds a curvature to the attenuation formula.

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.

void Ogre::Light::setCustomShadowCameraSetup | ( | const ShadowCameraSetupPtr & | customShadowSetup | ) |

| Set this light to use a custom shadow camera when rendering texture shadows. Remarks: This changes the shadow camera setup for just this light, you can set the shadow camera setup globally using SceneManager::setShadowCameraSetup See also: ShadowCameraSetup

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 void Ogre::MovableObject::setDefaultVisibilityFlags | ( | uint32 | flags | ) | `[static, inherited]`

| Set the default visibility flags for all future MovableObject instances. Definition at line 377 of file OgreMovableObject.h.

void Ogre::Light::setDiffuseColour | ( | const ColourValue & | colour | ) |

| Sets the colour of the diffuse light given off by this source. Remarks: Material objects have ambient, diffuse and specular values which indicate how much of each type of light an object reflects. This value denotes the amount and colour of this type of light the light exudes into the scene. The actual appearance of objects is a combination of the two. Diffuse light simulates the typical light emenating from light sources and affects the base colour of objects together with ambient light.

void Ogre::Light::setDiffuseColour | ( | Real | red,
|  | Real | green,
|  | Real | blue
| ) |

| Sets the colour of the diffuse light given off by this source. Remarks: Material objects have ambient, diffuse and specular values which indicate how much of each type of light an object reflects. This value denotes the amount and colour of this type of light the light exudes into the scene. The actual appearance of objects is a combination of the two. Diffuse light simulates the typical light emenating from light sources and affects the base colour of objects together with ambient light.

void Ogre::Light::setDirection | ( | const Vector3 & | vec | ) |

| Sets the direction in which a light points. Remarks: Applicable only to the spotlight and directional light types. Note: This will be overridden if the light is attached to a SceneNode.

void Ogre::Light::setDirection | ( | Real | x,
|  | Real | y,
|  | Real | z
| ) |

| Sets the direction in which a light points. Remarks: Applicable only to the spotlight and directional light types. Note: This will be overridden if the light is attached to a SceneNode.

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.

void Ogre::Light::setPosition | ( | const Vector3 & | vec | ) |

| Sets the position of the light. Remarks: Applicable to point lights and spotlights only. Note: This will be overridden if the light is attached to a SceneNode.

void Ogre::Light::setPosition | ( | Real | x,
|  | Real | y,
|  | Real | z
| ) |

| Sets the position of the light. Remarks: Applicable to point lights and spotlights only. Note: This will be overridden if the light is attached to a SceneNode.

void Ogre::Light::setPowerScale | ( | Real | power | ) |

  | Set a scaling factor to indicate the relative power of a light. Remarks: This factor is only useful in High Dynamic Range (HDR) rendering. You can bind it to a shader variable to take it into account, See also: GpuProgramParameters Parameters:
  | power | The power rating of this light, default is 1.0.

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::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 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.

void Ogre::Light::setSpecularColour | ( | const ColourValue & | colour | ) |

| Sets the colour of the specular light given off by this source. Remarks: Material objects have ambient, diffuse and specular values which indicate how much of each type of light an object reflects. This value denotes the amount and colour of this type of light the light exudes into the scene. The actual appearance of objects is a combination of the two. Specular light affects the appearance of shiny highlights on objects, and is also dependent on the 'shininess' Material value.

void Ogre::Light::setSpecularColour | ( | Real | red,
|  | Real | green,
|  | Real | blue
| ) |

| Sets the colour of the specular light given off by this source. Remarks: Material objects have ambient, diffuse and specular values which indicate how much of each type of light an object reflects. This value denotes the amount and colour of this type of light the light exudes into the scene. The actual appearance of objects is a combination of the two. Specular light affects the appearance of shiny highlights on objects, and is also dependent on the 'shininess' Material value.

void Ogre::Light::setSpotlightFalloff | ( | Real | val | ) |

| Sets the falloff between the inner and outer cones of the spotlight.

void Ogre::Light::setSpotlightInnerAngle | ( | const Radian & | val | ) |

| Sets the angle covered by the spotlights inner cone.

void Ogre::Light::setSpotlightOuterAngle | ( | const Radian & | val | ) |

| Sets the angle covered by the spotlights outer cone.

void Ogre::Light::setSpotlightRange | ( | const Radian & | innerAngle,
|  | const Radian & | outerAngle,
|  | Real | falloff = `1.0`
| ) |

  | Sets the range of a spotlight, i.e. the angle of the inner and outer cones and the rate of falloff between them. Parameters:
  | innerAngle | Angle covered by the bright inner cone The inner cone applicable only to Direct3D, it'll always treat as zero in OpenGL.
  | outerAngle | Angle covered by the outer cone
  | falloff | The rate of falloff between the inner and outer cones. 1.0 means a linear falloff, less means slower falloff, higher means faster falloff.

void Ogre::Light::setType | ( | LightTypes | type | ) |

| Sets the type of light - see LightTypes for more info.

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 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 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.

void Ogre::Light::setVisible | ( | bool | visible | ) | `[virtual]`

| Overridden from MovableObject. Remarks: Although lights themselves are not 'visible', setting a light to invisible means it no longer affects the scene. Reimplemented from Ogre::MovableObject.

virtual void Ogre::Light::update | ( | void |  | ) | const`[protected, virtual]`

| internal method for synchronising with parent node (if any)

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
