class UsdSchemaRegistry
 

Detailed Description

Base class for field primitives defined by an external file.

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

Definition at line 62 of file fieldAsset.h.

Constructor & Destructor Documentation

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

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

Definition at line 74 of file fieldAsset.h.

UsdVolFieldAsset::UsdVolFieldAsset ( const UsdSchemaBase schemaObj)
inlineexplicit

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

Definition at line 82 of file fieldAsset.h.

virtual USDVOL_API UsdVolFieldAsset::~UsdVolFieldAsset ( )

Destructor.

Member Function Documentation

USDVOL_API UsdSchemaKind UsdVolFieldAsset::_GetSchemaKind ( ) const

Reimplemented from UsdGeomXformable.

Reimplemented in UsdVolOpenVDBAsset.

USDVOL_API UsdAttribute UsdVolFieldAsset::CreateFieldDataTypeAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetFieldDataTypeAttr(), 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.

USDVOL_API UsdAttribute UsdVolFieldAsset::CreateFieldIndexAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetFieldIndexAttr(), 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.

USDVOL_API UsdAttribute UsdVolFieldAsset::CreateFieldNameAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetFieldNameAttr(), 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.

USDVOL_API UsdAttribute UsdVolFieldAsset::CreateFilePathAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetFilePathAttr(), 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.

USDVOL_API UsdAttribute UsdVolFieldAsset::CreateVectorDataRoleHintAttr ( VtValue const defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetVectorDataRoleHintAttr(), 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 USDVOL_API UsdVolFieldAsset UsdVolFieldAsset::Get ( const UsdStagePtr &  stage,
const SdfPath path 
)
static

Return a UsdVolFieldAsset 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:

UsdVolFieldAsset(stage->GetPrimAtPath(path));
USDVOL_API UsdAttribute UsdVolFieldAsset::GetFieldDataTypeAttr ( ) const

Token which is used to indicate the data type of an individual field. Authors use this to tell consumers more about the field without opening the file on disk. The list of allowed tokens is specified with the specific asset type. A missing value is considered an error.

Declaration token fieldDataType
C++ Type TfToken
Usd Type SdfValueTypeNames->Token
USDVOL_API UsdAttribute UsdVolFieldAsset::GetFieldIndexAttr ( ) const

A file can contain multiple fields with the same name. This optional attribute is an index used to disambiguate between these multiple fields with the same name.

Declaration int fieldIndex
C++ Type int
Usd Type SdfValueTypeNames->Int
USDVOL_API UsdAttribute UsdVolFieldAsset::GetFieldNameAttr ( ) const

Name of an individual field within the file specified by the filePath attribute.

Declaration token fieldName
C++ Type TfToken
Usd Type SdfValueTypeNames->Token
USDVOL_API UsdAttribute UsdVolFieldAsset::GetFilePathAttr ( ) const

An asset path attribute that points to a file on disk. For each supported file format, a separate FieldAsset subclass is required.

This attribute's value can be animated over time, as most volume asset formats represent just a single timeSample of a volume. However, it does not, at this time, support any pattern substitutions like "$F".

Declaration asset filePath
C++ Type SdfAssetPath
Usd Type SdfValueTypeNames->Asset
static USDVOL_API const TfTokenVector& UsdVolFieldAsset::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.

USDVOL_API UsdAttribute UsdVolFieldAsset::GetVectorDataRoleHintAttr ( ) const

Optional token which is used to indicate the role of a vector valued field. This can drive the data type in which fields are made available in a renderer or whether the vector values are to be transformed.

Declaration token vectorDataRoleHint = "None"
C++ Type TfToken
Usd Type SdfValueTypeNames->Token
Allowed Values None, Point, Normal, Vector, Color
