Detailed Description

Light emitted inward from a distant external environment, such as a sky or IBL light probe.

In this version of the dome light, the dome's default orientation is such that its top pole is aligned with the world's +Y axis. This adheres to the OpenEXR specification for latlong environment maps. From the OpenEXR documentation:


Latitude-Longitude Map:

The environment is projected onto the image using polar coordinates (latitude and longitude). A pixel's x coordinate corresponds to its longitude, and the y coordinate corresponds to its latitude. Pixel (dataWindow.min.x, dataWindow.min.y) has latitude +pi/2 and longitude +pi; pixel (dataWindow.max.x, dataWindow.max.y) has latitude -pi/2 and longitude -pi.

In 3D space, latitudes -pi/2 and +pi/2 correspond to the negative and positive y direction. Latitude 0, longitude 0 points into positive z direction; and latitude 0, longitude pi/2 points into positive x direction.

The size of the data window should be 2*N by N pixels (width by height),

where N can be any integer greater than 0.

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

Constructor & Destructor Documentation

◆ UsdLuxDomeLight() [1/2]

UsdLuxDomeLight ( const UsdPrim prim = UsdPrim())
inlineexplicit

Construct a UsdLuxDomeLight on UsdPrim prim .

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

Definition at line 100 of file domeLight.h.

◆ UsdLuxDomeLight() [2/2]

UsdLuxDomeLight ( const UsdSchemaBase schemaObj)
inlineexplicit

Construct a UsdLuxDomeLight on the prim held by schemaObj .

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

◆ _GetSchemaKind()

USDLUX_API UsdSchemaKind _GetSchemaKind ( ) const
overrideprotectedvirtual

Returns the kind of schema this class belongs to.

UsdSchemaKind

Reimplemented from UsdGeomXformable.

◆ CreateGuideRadiusAttr()

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

See GetGuideRadiusAttr(), 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.

◆ CreatePortalsRel()

USDLUX_API UsdRelationship CreatePortalsRel ( ) const

See GetPortalsRel(), and also Create vs Get Property Methods for when to use Get vs Create.

◆ CreateTextureFileAttr()

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

See GetTextureFileAttr(), 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.

◆ CreateTextureFormatAttr()

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

See GetTextureFormatAttr(), 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.

◆ Define()

static USDLUX_API UsdLuxDomeLight 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.

◆ Get()

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

Return a UsdLuxDomeLight 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:

UsdLuxDomeLight(stage->GetPrimAtPath(path));
Light emitted inward from a distant external environment, such as a sky or IBL light probe.
Definition: domeLight.h:89

◆ GetGuideRadiusAttr()

USDLUX_API UsdAttribute GetGuideRadiusAttr ( ) const

The radius of guide geometry to use to visualize the dome light.

The default is 1 km for scenes whose metersPerUnit is the USD default of 0.01 (i.e., 1 world unit is 1 cm).

Declaration float guideRadius = 100000
C++ Type float
Usd Type SdfValueTypeNames->Float

◆ GetPortalsRel()

USDLUX_API UsdRelationship GetPortalsRel ( ) const

Optional portals to guide light sampling.

◆ GetSchemaAttributeNames()

static USDLUX_API const TfTokenVector & 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.

◆ GetTextureFileAttr()

USDLUX_API UsdAttribute GetTextureFileAttr ( ) const

A color texture to use on the dome, such as an HDR (high dynamic range) texture intended for IBL (image based lighting).

Declaration asset inputs:texture:file
C++ Type SdfAssetPath
Usd Type SdfValueTypeNames->Asset

◆ GetTextureFormatAttr()

USDLUX_API UsdAttribute GetTextureFormatAttr ( ) const

Specifies the parameterization of the color map file.

Valid values are:

  • automatic: Tries to determine the layout from the file itself. For example, Renderman texture files embed an explicit parameterization.
  • latlong: Latitude as X, longitude as Y.
  • mirroredBall: An image of the environment reflected in a sphere, using an implicitly orthogonal projection.
  • angular: Similar to mirroredBall but the radial dimension is mapped linearly to the angle, providing better sampling at the edges.
  • cubeMapVerticalCross: A cube map with faces laid out as a vertical cross.
Declaration token inputs:texture:format = "automatic"
C++ Type TfToken
Usd Type SdfValueTypeNames->Token
Allowed Values automatic, latlong, mirroredBall, angular, cubeMapVerticalCross

◆ OrientToStageUpAxis()

USDLUX_API void OrientToStageUpAxis ( ) const

Adds a transformation op, if neeeded, to orient the dome to align with the stage's up axis.

Uses UsdLuxTokens->orientToStageUpAxis as the op suffix. If an op with this suffix already exists, this method assumes it is already applying the proper correction and does nothing further. If no op is required to match the stage's up axis, no op will be created.
