Detailed Description

Deprecated:: RenderMan-specific light filter settings will move to a new schema in a future release.

Renderman-specific attributes for light filters.

For any described attribute Fallback Value or Allowed Values below that are text/tokens, the actual token is published and defined in UsdRiTokens. So to set an attribute to the value "rightHanded", use UsdRiTokens->rightHanded as the value.

Constructor & Destructor Documentation

UsdRiLightFilterAPI::UsdRiLightFilterAPI ( const UsdPrim & prim = UsdPrim() )

inlineexplicit

Construct a UsdRiLightFilterAPI on UsdPrim prim . Equivalent to UsdRiLightFilterAPI::Get(prim.GetStage(), prim.GetPath()) for a valid prim, but will not immediately throw an error for an invalid prim

Definition at line 78 of file lightFilterAPI.h.

UsdRiLightFilterAPI::UsdRiLightFilterAPI ( const UsdSchemaBase & schemaObj )

inlineexplicit

Construct a UsdRiLightFilterAPI on the prim held by schemaObj . Should be preferred over UsdRiLightFilterAPI(schemaObj.GetPrim()), as it preserves SchemaBase state.

Definition at line 86 of file lightFilterAPI.h.

virtual USDRI_API UsdRiLightFilterAPI::~UsdRiLightFilterAPI ( )

virtual

Destructor.

Member Function Documentation

USDRI_API UsdSchemaType UsdRiLightFilterAPI::_GetSchemaType ( ) const

overrideprotectedvirtual

Returns the type of schema this class belongs to.

See Also: UsdSchemaType

Reimplemented from UsdAPISchemaBase.

static USDRI_API UsdRiLightFilterAPI UsdRiLightFilterAPI::Apply ( const UsdPrim & prim )

static

Applies this single-apply API schema to the given prim. This information is stored by adding "RiLightFilterAPI" to the token-valued, listOp metadata apiSchemas on the prim.

Returns: A valid UsdRiLightFilterAPI object is returned upon success. An invalid (or empty) UsdRiLightFilterAPI object is returned upon failure. See UsdPrim::ApplyAPI() for conditions resulting in failure.

USDRI_API UsdAttribute UsdRiLightFilterAPI::CreateRiIntensityAttr	(	VtValue const &	defaultValue = `VtValue()`,
		bool	writeSparsely = `false`
	)		const

See GetRiIntensityAttr(), and also Usd_Create_Or_Get_Property for when to use Get vs Create. If specified, author defaultValue as the attribute's default, sparsely (when it makes sense to do so) if writeSparsely is true - the default for writeSparsely is false.

USDRI_API UsdAttribute UsdRiLightFilterAPI::CreateRiInvertAttr	(	VtValue const &	defaultValue = `VtValue()`,

static USDRI_API UsdRiLightFilterAPI UsdRiLightFilterAPI::Get	(	const UsdStagePtr &	stage,
		const SdfPath &	path
	)

static

Return a UsdRiLightFilterAPI holding the prim adhering to this schema at path on stage. If no prim exists at path on stage, or if the prim at that path does not adhere to this schema, return an invalid schema object. This is shorthand for the following:

UsdRiLightFilterAPI(stage->GetPrimAtPath(path));

USDRI_API UsdAttribute UsdRiLightFilterAPI::GetRiCombineModeAttr ( ) const

Specifies how this filter combines with others. Valid values are:

multiply: The results of filters are multiplied together
max: The maximum result of the filters is used. This works best for grey-scale filters.
min: The minimum result of the filters is used. This works best for grey-scale filters.
screen: Similar to max, but combines gradients in a smoother way by using a screen operation:
```
screen(a,b) = 1-(1-a)(1-b)
```
This works best for grey-scale filters.

Light filters on a light are grouped by their combine mode. Each group is executed and combined using that mode. Then, the final results of each group are multiplied together.

Fallback: multiply
