Detailed Description

Light emitted outward from a sphere.

Definition at line 57 of file sphereLight.h.

Constructor & Destructor Documentation

UsdLuxSphereLight ( const UsdPrim prim = UsdPrim())
inlineexplicit

Construct a UsdLuxSphereLight on UsdPrim prim .

Equivalent to UsdLuxSphereLight::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 sphereLight.h.

UsdLuxSphereLight ( const UsdSchemaBase schemaObj)
inlineexplicit

Construct a UsdLuxSphereLight on the prim held by schemaObj .

Should be preferred over UsdLuxSphereLight(schemaObj.GetPrim()), as it preserves SchemaBase state.

Returns the type of schema this class belongs to.

UsdSchemaType

Reimplemented from UsdLuxLight.

USDLUX_API UsdAttribute CreateRadiusAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetRadiusAttr(), and also Create vs Get Property Methods 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 CreateTreatAsPointAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetTreatAsPointAttr(), and also Create vs Get Property Methods 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 UsdLuxSphereLight Define ( const UsdStagePtr &  stage,
const SdfPath path 
)
static

Attempt to ensure a UsdPrim adhering to this schema at path is defined (according to UsdPrim::IsDefined()) on this stage.

If a prim adhering to this schema at path is already defined on this stage, return that prim. Otherwise author an SdfPrimSpec with specifier == SdfSpecifierDef and this schema's prim type name for the prim at path at the current EditTarget. Author SdfPrimSpec s with specifier == SdfSpecifierDef and empty typeName at the current EditTarget for any nonexistent, or existing but not Defined ancestors.

The given path must be an absolute prim path that does not contain any variant selections.

If it is impossible to author any of the necessary PrimSpecs, (for example, in case path cannot map to the current UsdEditTarget's namespace) issue an error and return an invalid UsdPrim.

Note that this method may return a defined prim whose typeName does not specify this schema class, in case a stronger typeName opinion overrides the opinion at the current EditTarget.

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

Return a UsdLuxSphereLight 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:

* UsdLuxSphereLight(stage->GetPrimAtPath(path));
*
