Detailed Description

Controls for shaping a light's emission.

Constructor & Destructor Documentation

UsdLuxShapingAPI::UsdLuxShapingAPI ( const UsdPrim prim = UsdPrim())
inlineexplicit

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

Definition at line 69 of file shapingAPI.h.

UsdLuxShapingAPI::UsdLuxShapingAPI ( const UsdSchemaBase schemaObj)
inlineexplicit

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

Definition at line 77 of file shapingAPI.h.

virtual USDLUX_API UsdLuxShapingAPI::~UsdLuxShapingAPI ( )
virtual

Destructor.

Member Function Documentation

USDLUX_API UsdSchemaType UsdLuxShapingAPI::_GetSchemaType ( ) const
overrideprotectedvirtual

Returns the type of schema this class belongs to.

See Also
UsdSchemaType

Reimplemented from UsdAPISchemaBase.

static USDLUX_API UsdLuxShapingAPI UsdLuxShapingAPI::Apply ( const UsdPrim prim)
static

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

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

bool  writeSparsely = false 
) const

See GetShapingConeAngleAttr(), 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.

USDLUX_API UsdAttribute UsdLuxShapingAPI::CreateShapingConeSoftnessAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetShapingConeSoftnessAttr(), 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.

USDLUX_API UsdAttribute UsdLuxShapingAPI::CreateShapingFocusAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetShapingFocusAttr(), 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.

USDLUX_API UsdAttribute UsdLuxShapingAPI::CreateShapingFocusTintAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetShapingFocusTintAttr(), 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.

USDLUX_API UsdAttribute UsdLuxShapingAPI::CreateShapingIesAngleScaleAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetShapingIesAngleScaleAttr(), 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.

USDLUX_API UsdAttribute UsdLuxShapingAPI::CreateShapingIesFileAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetShapingIesFileAttr(), 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.

USDLUX_API UsdAttribute UsdLuxShapingAPI::CreateShapingIesNormalizeAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetShapingIesNormalizeAttr(), 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.

static USDLUX_API UsdLuxShapingAPI UsdLuxShapingAPI::Get ( const UsdStagePtr &  stage,
const SdfPath path 
)
static

Return a UsdLuxShapingAPI 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:

UsdLuxShapingAPI(stage->GetPrimAtPath(path));
static USDLUX_API const TfTokenVector& UsdLuxShapingAPI::GetSchemaAttributeNames ( bool  includeInherited = true)
static

Return a vector of names of all pre-declared attributes for this schema class and all its ancestor classes. Does not include attributes that may be authored by custom/extended methods of the schemas involved.

USDLUX_API UsdAttribute UsdLuxShapingAPI::GetShapingConeAngleAttr ( ) const

Angular limit off the primary axis to restrict the light spread.

Declaration float shaping:cone:angle = 90
C++ Type float
Usd Type SdfValueTypeNames->Float
USDLUX_API UsdAttribute UsdLuxShapingAPI::GetShapingConeSoftnessAttr ( ) const

Controls the cutoff softness for cone angle. TODO: clarify semantics

Declaration float shaping:cone:softness = 0
C++ Type float
Usd Type SdfValueTypeNames->Float
USDLUX_API UsdAttribute UsdLuxShapingAPI::GetShapingFocusAttr ( ) const

A control to shape the spread of light. Higher focus values pull light towards the center and narrow the spread. Implemented as an off-axis cosine power exponent. TODO: clarify semantics

Declaration float shaping:focus = 0
C++ Type float
Usd Type SdfValueTypeNames->Float
USDLUX_API UsdAttribute UsdLuxShapingAPI::GetShapingFocusTintAttr ( ) const

Off-axis color tint. This tints the emission in the falloff region. The default tint is black. TODO: clarify semantics

Declaration color3f shaping:focusTint = (0, 0, 0)
C++ Type GfVec3f
Usd Type SdfValueTypeNames->Color3f
USDLUX_API UsdAttribute UsdLuxShapingAPI::GetShapingIesAngleScaleAttr ( ) const

Rescales the angular distribution of the IES profile. TODO: clarify semantics

Declaration float shaping:ies:angleScale = 0
C++ Type float
Usd Type SdfValueTypeNames->Float
USDLUX_API UsdAttribute UsdLuxShapingAPI::GetShapingIesFileAttr ( ) const

An IES (Illumination Engineering Society) light profile describing the angular distribution of light.

Declaration asset shaping:ies:file
C++ Type SdfAssetPath
Usd Type SdfValueTypeNames->Asset
USDLUX_API UsdAttribute UsdLuxShapingAPI::GetShapingIesNormalizeAttr ( ) const

Normalizes the IES profile so that it affects the shaping of the light while preserving the overall energy output.
