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 diffuse 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. Starting Ogre 2.0 all Lights must be associated to a SceneNode in order to work; which holds the position and direction. Light::setDirection and Light::getDirection will redirect to the SceneNode and assert or crash if not attached to one.
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 tessellation and the normals are properly set. This is particularly true for the spotlight which will only look right on highly tessellated 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.

@See SceneManager::cullFrustum

Remarks
We don't pass by reference on purpose (avoid implicit aliasing) We perform frustum culling AND test visibility mask at the same time
Parameters
frustumFrustum to clip against
sceneVisibilityFlagsCombined scene's visibility flags (i.e. viewport | scene). Set LAYER_SHADOW_CASTER bit if you want to exclude non-shadow casters.
outCulledObjectsOut. List of objects that are (fully or partially) inside the frustum and should be rendered
lodCameraCamera in which lod levels calculations are based (i.e. during shadow pass renders) Note however, we only use this camera to calulate if should be visible according to mUpperDistance

Member Enumeration Documentation

◆ LightTypes

Defines the type of light.

Enumerator
LT_DIRECTIONAL 

Directional lights simulate parallel light beams from a distant source, hence have direction but no position.

LT_POINT 

Point light sources give off light equally in all directions, so require only position not direction.

LT_SPOTLIGHT 

Spotlights simulate a cone of light from a source so require position and direction, plus extra values for falloff.

LT_VPL 

Virtual point lights, used for Instant Radiosity (Global Illumination fake / approximation)

MAX_FORWARD_PLUS_LIGHTS 
LT_AREA_APPROX 

Non-PBR version of Area lights.

Not an accurate approximation, but they're flexible, useful & cheap. They aren't physically correct at all.

LT_AREA_LTC 

PBR version of Area lights using Linearly Transformed Cosines as researched by Eric Heitz, Jonathan Dupuy, Stephen Hill and David Neubelt.

It's slower than LT_AREA_APPROX, and does not currently support textures. However it's physically accurate.

NUM_LIGHT_TYPES 

◆ Reason

Enumerator
Unknown 
FromStorageToSysRam 

OnStorage -> OnSystemRam.

FromSysRamToStorage 

OnSystemRam -> OnStorage.

GainedResidency 

OnStorage -> Resident OnSystemRam -> Resident See ReadyForRendering.

LostResidency 

Resident -> OnStorage Resident -> OnSystemRam.

PoolTextureSlotChanged 
ResidentToSysRamSync 

Only called while TextureGpu is still Resident, and strategy is AlwaysKeepSystemRamCopy.

This listener happens when something was done to the TextureGpu that modifies its contents in the GPU, and were thus forced to sync those values back to SystemRam. This listener calls tells that sync is over.

MetadataCacheOutOfDate 

The Metadata cache was out of date and we had to do a ping-pong.

Expect this to be followed by at least LostResidency and GainedResidency calls

This is very important, because if you were expecting certain sequence of calls (e.g. you were expecting a LostResidency soon to arrive), expect that to be changed.

See TextureGpuManager for details about the metadata cache.

ExceptionThrown 

Called when the worker thread caught an exception.

This exception has already been logged, and the texture resumed loading normally with a white 2x2 RGBA8 fallback.

This listener will get called from the main thread.

The texture may still have pending residency transitions (e.g. it may still be loading the 2x2 fallback)

Cast Exception e = reinterpret_cast<Exception>( extraData ); to know more info

FsaaSettingAlteredByApi 

Requested FSAA (MSAA / CSAA / EQAA / etc) is not supported by the API, and thus the setting had to be downgraded.

Note this may happen on device lost, and a new GPU became in use; thus it's possible for a TextureGpu to initially support certain FSAA but later change.

ReadyForRendering 

This Reason is called when TextureGpu::notifyDataIsReady is called.

This normally means worker thread is done loading texture from file and uploading it to GPU; and can now be used for rendering. It does NOT mean that Ogre has finished issueing rendering commands to a RenderTexture and is now ready to be presented to the monitor.

◆ _updateCustomGpuParameter()

virtual void Ogre::Light::_updateCustomGpuParameter ( uint16  paramIndex,
const GpuProgramParameters_AutoConstantEntry constantEntry,
GpuProgramParameters params 
) const
virtual

Update a custom GpuProgramParameters constant which is derived from information only this Light knows.

Remarks
This method allows a Light to map in a custom GPU program parameter based on it's own data. This is represented by a GPU auto parameter of ACT_LIGHT_CUSTOM, and to allow there to be more than one of these per Light, the 'data' field on the auto parameter will identify which parameter is being updated and on which light. The implementation of this method must identify the parameter being updated, and call a 'setConstant' method on the passed in GpuProgramParameters object.
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
paramIndexThe index of the constant being updated
constantEntryThe auto constant entry from the program parameters
paramsThe parameters object which this method should call to set the updated parameters.

◆ _updateRenderQueue()

virtual void Ogre::Light::_updateRenderQueue ( RenderQueue queue,

◆ resetShadowFarDistance()

void Ogre::Light::resetShadowFarDistance ( void  )

Tells the light to use the shadow far distance of the SceneManager.

◆ setAffectParentNode()

void Ogre::Light::setAffectParentNode ( bool  bAffect)

A Light must always have a Node attached to it.

The direction is taken from the node's orientation, and thus setDirection modifies the attached node directly.

However, when changing the range and the spot falloff; the node is not affected. This is intentional in case you want to create (e.g.) a node for a flashlight, and attach both the flashlight entity and the light to the same node; thus controlling the node moves both the flashlight and its visual effect.
Despite this, there are cases where you want the changes to this light to be reflected in the parent node: The most common example are light volumes in deferred shading setups, and debug objects.
Remarks
This setting is only useful for non-directional lights. For point lights, the scale is calculated as setSize( range, range, range ) which means a light volume should be a sphere of radius = 1;
For spot lights, the scale is calc. as setSize( tan( outerAngle * 0.5 * range ), tan( outerAngle * 0.5 * range ), range ); which means a light volume should be a cone with Z = 1, and X & Y = 2
Parameters
bAffectWhen true, the scene node is affected and modified by changes to range and falloff.

◆ setAttenuation()

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

Sets the attenuation parameters of the light source i.e.

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 attenuation 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
rangeThe absolute upper range of the light in world units.
constantThe constant factor in the attenuation formula: 1.0 means never attenuate, 0.0 is complete attenuation.
linearThe linear factor in the attenuation formula: 1 means attenuate evenly over the distance.
quadraticThe quadratic factor in the attenuation formula: adds a curvature to the attenuation formula.

◆ setAttenuationBasedOnRadius()

void Ogre::Light::setAttenuationBasedOnRadius ( Real  radius,
Real  lumThreshold 
)

Sets the attenuation parameters (range, constant, linear & quadratic,.

See also
setAttenuation) based on a given radius.
Remarks
The actual attenuation formula is:

1

(distance / radius)² * 0.5 + 0.5

The original formula never ends, that is the range is infinity. This function calculates a range based on "lumThreshold": When the luminosity past certain distance is below the established threshold, the light calculations are cut.

Parameters
radiusThe radius of the light. i.e. A light bulb is a couple centimeters, the sun is ~696km; but be sure to be consistent in the unit of measurement you use (i.e. don't use km if your default unit is in meters). Note: Having a radius = 2 means that at distance = 2 the pixel is lit 100% Anything inside that radius (which is supposedly impossible) will have more than 100% light power.
lumThresholdValue in the range [0; 1) Sets range at which the luminance (in percentage) of a point would go below the threshold. For example lumThreshold = 0 means the attenuation range is infinity; lumThreshold = 1 means the range is set to 0.
The value you want as threshold to use depends on your HDR pipeline and the power of the light. For example, with a power = 1 in LDR, a lumThreshold < 1 / 255 (roughly 0.00392) is pointless. Past that point the actual RGB value will always be (0, 0, 0). But for an LDR pipeline with a light power of 50, lumThreshold < 1 / (255 * 50) is pointless. For an HDR pipeline, the answer is more faint, as it depends on the threshold of your HDR tonemapping past which it stops adjusting the exposure.

◆ setCastShadows()

void Ogre::MovableObject::setCastShadows ( bool  enabled)
inlineinherited

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.

◆ setCustomParameter()

void Ogre::Light::setCustomParameter ( uint16  index,
const Vector4 value 
)

Sets a custom parameter for this Light, 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 Light. This is most useful if the material which this Renderable uses a vertex or fragment program, and has an ACT_LIGHT_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
indexThe 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_LIGHT_CUSTOM entry, if that is used.
valueThe value to associate.

◆ setDefaultLightMask()

static void Ogre::MovableObject::setDefaultLightMask ( uint32  mask)
inlinestaticinherited

Set the default light mask for all future MovableObject instances.

◆ setDiffuseColour() [1/2]

void Ogre::Light::setDiffuseColour ( const ColourValue colour)
inline

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 emanating from light sources and affects the base colour of objects together with ambient light.

◆ setDiffuseColour() [2/2]

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

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 emanating from light sources and affects the base colour of objects together with ambient light.

◆ setDirection()

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

For area lights and custom 2d shapes, specifies whether the light lits in both directions (positive & negative sides of the plane) or if only towards one.

Parameters
bDoubleSidedTrue to enable. Default: false.

◆ setLightMask()

void Ogre::MovableObject::setLightMask ( uint32  lightMask)
inlineinherited

Set a bitwise mask which will filter the lights affecting this object.

Remarks
This mask will be compared against the mask held against Light to determine if a light should affect a given object. By default, this mask is fully set meaning all lights will affect this object

◆ setListener()

void Ogre::MovableObject::setListener ( Listener listener)
inlineinherited

◆ setPowerScale()

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

See also
GpuProgramParameters
Parameters
powerThe power rating of this light, default is 1.0.

◆ setQueryFlags()

void Ogre::MovableObject::setQueryFlags ( uint32  flags)
inlineinherited

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.

◆ setRectSize()

void Ogre::Light::setRectSize ( Vector2  rectSize)

For custom 2D shape and area lights, sets the dimensions of the rectangle, in half size.

Parameters
halfSize

◆ setRenderingDistance()

void Ogre::MovableObject::setRenderingDistance ( Real  dist)
inlineinherited

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

Parameters
distDistance beyond which the object will not be rendered (the default is FLT_MAX, which means objects are always rendered). Values equal or below zero will be ignored, and cause an assertion in debug mode.

◆ setRenderingMinPixelSize()

void Ogre::MovableObject::setRenderingMinPixelSize ( Real  pixelSize)
inlineinherited

Sets the minimum pixel size an object needs to be in both screen axes in order to be rendered.

Note
Camera::setUseMinPixelSize() needs to be called for this parameter to be used.
Parameters
pixelSizeNumber of minimum pixels (the default is 0, which means objects are always rendered).

◆ setRenderQueueGroup()

virtual void Ogre::Light::setRenderQueueGroup ( uint8  queueID)

Reimplemented from Ogre::MovableObject.

◆ setShadowFarClipDistance()

void Ogre::Light::setShadowFarClipDistance ( Real  farClip)
inline

Set the far clip plane distance to be used by the shadow camera, if this light casts texture shadows.

Remarks
This is different from the 'shadow far distance', which is always measured from the main camera. This distance is the far clip plane of the light camera.
Parameters
farClipThe distance, or -1 to use the main camera setting.

◆ setShadowFarDistance()

void Ogre::Light::setShadowFarDistance ( Real  distance)

Sets the maximum distance away from the camera that shadows by this light will be visible.

Remarks
Shadow techniques can be expensive, therefore it is a good idea to limit them to being rendered close to the camera if possible, and to skip the expense of rendering shadows for distance objects. This method allows you to set the distance at which shadows will no longer be rendered.
Note
Each shadow technique can interpret this subtely differently. For example, one technique may use this to eliminate casters, another might use it to attenuate the shadows themselves. You should tweak this value to suit your chosen shadow technique and scene setup.

◆ setShadowNearClipDistance()

void Ogre::Light::setShadowNearClipDistance ( Real  nearClip)
inline

Set the near clip plane distance to be used by the shadow camera, if this light casts texture shadows.

Parameters
nearClipThe distance, or -1 to use the main camera setting.

void Ogre::MovableObject::setShadowRenderingDistance ( Real  dist)
inlineinherited

Sets the distance at which the object is no longer casting shadows.

Parameters
distDistance beyond which the object will not cast shadows (the default is FLT_MAX, which means objects are always casting shadows). Values equal or below zero will be ignored, and cause an assertion in debug mode.
Note
ShadowRenderingDistance will be clamped to RenderingDistance value

◆ setSpecularColour() [1/2]

void Ogre::Light::setSpecularColour ( const ColourValue colour)
inline

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.

◆ setSpecularColour() [2/2]

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

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.

◆ setSpotlightFalloff()

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

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

◆ setSpotlightInnerAngle()

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

Sets the angle covered by the spotlights inner cone.

◆ setSpotlightNearClipDistance()

void Ogre::Light::setSpotlightNearClipDistance ( Real  nearClip)
inline

Set the near clip plane distance to be used by spotlights that use light clipping, allowing you to render spots as if they start from further down their frustum.

Parameters
nearClipThe near distance.

◆ setSpotlightOuterAngle()

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

Sets the angle covered by the spotlights outer cone.

◆ setSpotlightRange()

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
innerAngleAngle covered by the bright inner cone
Note
The inner cone applicable only to Direct3D, it'll always treat as zero in OpenGL.
Parameters
outerAngleAngle covered by the outer cone
falloffThe rate of falloff between the inner and outer cones. 1.0 means a linear falloff, less means slower falloff, higher means faster falloff.

◆ setStatic()

bool Ogre::MovableObject::setStatic ( bool  bStatic)
inherited

Turns this Node into static or dynamic.

Remarks
Switching between dynamic and static has some overhead and forces to update all static scene when converted to static. So don't do it frequently. Static objects are not updated every frame, only when requested explicitly. Use this feature if you plan to have this object unaltered for a very long times
Note all MovableObjects support switching between static & dynamic after they have been created (eg. InstancedEntity)
Changing this attribute will cause to switch the attribute to our parent node, and as a result, all of its other attached entities. @See Node::setStatic
Returns
True if setStatic made an actual change. False otherwise. Can fail because the object was already static/dynamic, or because switching is not supported

◆ setTexture()

void Ogre::Light::setTexture ( TextureGpu texture)

Sets a textured for types of light that support it.

At the time of writing only LT_AREA_APPROX supports it.

Remarks
Note that HlmsPbs only supports one 2D Array texture active at a time. i.e. you must call hlmsPbs->setAreaLightMasks( texture ); and if that texture belongs to a different pool as the one you're inputting here, the wrong texture will be displayed!
Parameters
textureTexture. Can be monochrome or coloured. For Raw version must be a 2D Array texture. For non-Raw version, must be a 2D texture.
sliceIdxSlice to the texture.

◆ setTextureRaw()

void Ogre::Light::setTextureRaw ( TextureGpu texture,
uint32  sliceIdx 
)

◆ setType()

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

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

◆ setVisibilityFlags()

void Ogre::MovableObject::setVisibilityFlags ( uint32  flags)
inlineinherited

Sets the visibility flags for this object.

Remarks
As well as a simple true/false value for visibility (as seen in setVisible), you can also set visibility flags that is applied a binary 'and' with the SceneManager's mask and a compositor node pass. To exclude particular objects from rendering. Changes to reserved visibility flags are ignored (won't take effect).

◆ setVisible()

void Ogre::MovableObject::setVisible ( bool  visible)
inlineinherited

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.

◆ shouldStayLoaded()

virtual bool Ogre::TextureGpuListener::shouldStayLoaded ( TextureGpu texture)
inlinevirtualinherited

Return true if this TextureGpu should likely stay loaded or else graphical changes could occur.

Return false if it is certainly safe to unload.

Reimplemented in Ogre::VctLighting, and Ogre::OGRE_HLMS_TEXTURE_BASE_CLASS.

◆ updateAllBounds()

static void Ogre::MovableObject::updateAllBounds ( const size_t  numNodes,
ObjectData  t 
)
staticinherited

@See SceneManager::updateAllBounds

Remarks
We don't pass by reference on purpose (avoid implicit aliasing)

◆ mGlobalIndex

size_t Ogre::MovableObject::mGlobalIndex
inherited

Index in the vector holding this MO reference (could be our parent node, or a global array tracking all movable objecst to avoid memory leaks).

Used for O(1) removals.

Remarks
It is the parent (or our creator) the one that sets this value, not ourselves. Do NOT modify it manually.

◆ mParentIndex

size_t Ogre::MovableObject::mParentIndex
