virtual Enlighten::InterpolationInputSet const* Enlighten::IProbeSetManager::GetInterpolationInputSet

public: Enlighten::InterpolationInputSet const * GetInterpolationInputSet
(
Geo::u32 index
) const

Get an interpolation set that corresponds to given index - this index needs to be comaptible with ProbeInterpolant::m_ProbeSetIndex filled by the GetProbeInterpolants(...) method.

May return NULL is Probe Set that corresponds to index is unloaded. Note, however that none of the ProbeInterpolant::m_ProbeSetIndex indices returned from GetProbeInterpolants(...) should correspond to an unloaded Probe Sets.

Returns

The InterpolationI Input Set for a given index or NULL if that Probe Set in unloaded.

virtual bool Enlighten::IProbeSetManager::GetLodRangeProbeInterpolants

public: virtual bool GetLodRangeProbeInterpolants
(
Geo::v128 const & point,

Geo::u32 numLods
) const

Retrieves the probes interpolants for a given point and specified range of LODs.

Only loaded Probe Sets are considered for interpolation. This interface is only supported to enable Transparency and Contributing Probe when using Probe LOD with PPPI.

Parameters

[out]	interpolants	Output probe interpolants array with size numMaxInterpolants * numLods.
[in]	numMaxInterpolants	Maximum number of interpolants that may be output for each LOD.
[out]	numUsedInterpolants	Array to which is output the number of interpolants used for each LOD.
[in]	numLods	The range of LODs [0, numLods) for which interpolants should be returned.

Returns

TRUE if the input to this function is valid and the interpolation is successful, otherwise FALSE.

virtual bool Enlighten::IProbeSetManager::GetMaxWeightForProbeSet

public: bool GetMaxWeightForProbeSet
(
Geo::GeoGuid const & probeSet,
float & maxWeight
) const

Set a maximum interpolation weight for the given Probe Set.

. Needs to perform a search OLog(N). Where N is number of probe sets under management.

Parameters

[in]	probeSet	The GUID of the Probe Set.
[out]	maxWeight	New maximum interpolation weight.

Returns

TRUE if the Probe Set is under ProbeSetManager management, otherwise FALSE.

virtual Geo::s32 Enlighten::IProbeSetManager::GetNumProbeSets

public: Geo::s32 GetNumProbeSets() const

Get the total number of Probe Sets under management.

Returns

the total number of Probe Sets under management.

virtual bool Enlighten::IProbeSetManager::GetProbeInterpolants

public: bool GetProbeInterpolants
(
Geo::v128 const & point,
ProbeInterpolant * interpolants,
Geo::s32 numMaxInterpolants,
Geo::s32 & numUsedInterpolants
) const

Retrieves the probes interpolants for a given point.

Only loaded Probe Sets are considered for interpolation.

Parameters

[in]	point	Location used for the interpolation.
[out]	interpolants	Output probe interpolants.
[in]	numMaxInterpolants	Size of the output interpolants array.
[out]	numUsedInterpolants	Number of interpolants actually used.

Returns

TRUE if the input to this function is valid and the interpolation is successful, otherwise FALSE.

virtual bool Enlighten::IProbeSetManager::GetProbeInterpolants

public: bool GetProbeInterpolants
(
Geo::v128 const & point,
ProbeInterpolant * interpolants,
Geo::s32 numMaxInterpolants,
Geo::s32 & numUsedInterpolants,
Geo::u32 lod
) const

Retrieves the probes interpolants for a given point and specified LOD.

Only loaded Probe Sets are considered for interpolation. This interface is only supported to enable Transparency and Contributing Probe when using Probe LOD with PPPI.

Parameters

[in]	point	Location used for the interpolation.
[out]	interpolants	Output probe interpolants.
[in]	numMaxInterpolants	Size of the output interpolants array.
[out]	numUsedInterpolants	Number of interpolants actually used.
[in]	lod	The LOD to select which interpolants should be returned.

Returns

TRUE if the input to this function is valid and the interpolation is successful, otherwise FALSE.

virtual bool Enlighten::IProbeSetManager::MarkAllProbeSetsAsUnloaded

public: bool MarkAllProbeSetsAsUnloaded()

Marks all Interpolation Input Sets as unloaded.

Unloaded input sets are not used for interpolation.

Returns

TRUE if the InterpolationInputSet is under ProbeSetManager management and can be marked as unloaded, otherwise FALSE.

virtual bool Enlighten::IProbeSetManager::MarkProbeSetAsLoaded

public: bool MarkProbeSetAsLoaded
(
Enlighten::InterpolationInputSet const & loadedProbeSet
)

Marks given Interpolation Input Set as loaded.

Only loaded input sets are used for interpolation.

Parameters

[in]

loadedProbeSet

The Interpolation Input Set to be marked as loaded. It has to contain a valid RadProbeSetCore field.

Returns

TRUE if the InterpolationInputSet is under ProbeSetManager management and can be marked as loaded, otherwise FALSE.

virtual bool Enlighten::IProbeSetManager::MarkProbeSetAsUnloaded

public: bool MarkProbeSetAsUnloaded
(
Geo::GeoGuid const & unloadedProbeSet
)

Marks given Interpolation Input Set as unloaded.

Unloaded input sets are not used for interpolation.

Parameters

[in]

unloadedProbeSet

The GUID of the Probe Set to be marked as unloaded.

Returns

TRUE if the InterpolationInputSet is under ProbeSetManager management and can be marked as unloaded, otherwise FALSE.

virtual void Enlighten::IProbeSetManager::OnAllLoadedProbeSetsArrayChanged

public: virtual void OnAllLoadedProbeSetsArrayChanged
(
Enlighten::InterpolationInputSet const * allLoadedProbeSets,
Geo::s32 numLoadedProbeSets
)

Allows the probe set manager a chance to observe the contiguous memory block in which the runtime stores all loaded input sets.

The manager can then use this knowledge to speed up other operations as needed (e.g. if the manager's implementation of GetProbeInterpolants() uses the variant of Enlighten::GetProbeInterpolants() supporting multiple probe sets). Note that multiple load and unload notifications (as noted by MarkProbeSetAsLoaded and MarkProbeSetAsUnloaded, respectively) may be batched into a single call to this function.

Parameters

[in]	allLoadedProbeSets	Starting address of the input set array managed by the runtime.
[in]	numLoadedProbeSets	Size of the input set array.

virtual bool Enlighten::IProbeSetManager::SetMaxWeightForProbeSet

public: bool SetMaxWeightForProbeSet
(
Geo::GeoGuid const & probeSet,
float maxWeight
)

Set a maximum interpolation weight for the given Probe Set.

Needs to perform a search OLog(N). Where N is number of probe sets under management.

Parameters

[in]	probeSet	The GUID of the Probe Set.
[in]	maxWeight	New maximum interpolation weight. Has to be a value between 0.0 and 1.0

Returns

TRUE if the Probe Set is under ProbeSetManager management, otherwise FALSE.
