Functions

virtual BaseCubeMap* Enlighten::IUpdateManager::AllocateCubeMap

---

public: BaseCubeMap * AllocateCubeMap
(
    const RadCubeMapCore * coreData,
    IGpuTexture * outputTexture
)

---

Allocate a cube map object.

Pointer parameters that are are owned by the caller may be read any time after EnqueueAddCubeMap and before the completion of the async RemoveCubeMap command.

Parameters

virtual BaseDynamicObject* Enlighten::IUpdateManager::AllocateDynamicObject

---

public: BaseDynamicObject * AllocateDynamicObject
(
    const Enlighten::DynamicObject & dynamicObjectDesc
)

---

Allocate a dynamic object.

This will add the object to the update manager's list but it must be separately added to the worker's copy via EnqueueAddDynamicObject.

Parameters

---

public: BaseProbeSet * AllocateProbeSet
(
    const RadProbeSetCore * coreData,
    bool useU8Output,
    Enlighten::eSHOrder shOrder,
    RawBuffer output
)

---

Allocate a probe set object.

Pointer parameters that are are owned by the caller may be read (and output may be written) any time after EnqueueAddProbeSet and before the completion of the async RemoveProbeSet command.

Parameters

virtual BaseProbeSet* Enlighten::IUpdateManager::AllocateStaticProbeSet

---

public: BaseProbeSet * AllocateStaticProbeSet
(
    const RadProbeSetCore * coreData,
