Detailed Description

Represents an abstract generative procedural prim which delivers its input parameters via properties (including relationships) within the "primvars:" namespace.

It does not itself have any awareness or participation in the execution of the procedural but rather serves as a means of delivering a procedural's definition and input parameters.

The value of its "proceduralSystem" property (either authored or provided by API schema fallback) indicates to which system the procedural definition is meaningful.

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

Constructor & Destructor Documentation

UsdProcGenerativeProcedural::UsdProcGenerativeProcedural ( const UsdPrim &  prim = UsdPrim())
inlineexplicit

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

Definition at line 86 of file generativeProcedural.h.

UsdProcGenerativeProcedural::UsdProcGenerativeProcedural ( const UsdSchemaBase &  schemaObj)
inlineexplicit

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

Definition at line 94 of file generativeProcedural.h.

virtual USDPROC_API UsdProcGenerativeProcedural::~UsdProcGenerativeProcedural ( )
virtual

Destructor.

Member Function Documentation

USDPROC_API UsdSchemaKind UsdProcGenerativeProcedural::_GetSchemaKind ( ) const
overrideprotectedvirtual

Returns the kind of schema this class belongs to.

See Also
UsdSchemaKind

Reimplemented from UsdGeomBoundable.

USDPROC_API UsdAttribute UsdProcGenerativeProcedural::CreateProceduralSystemAttr ( VtValue const &  defaultValue = VtValue(),
bool  writeSparsely = false 
) const

See GetProceduralSystemAttr(), 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 USDPROC_API UsdProcGenerativeProcedural UsdProcGenerativeProcedural::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 USDPROC_API UsdProcGenerativeProcedural UsdProcGenerativeProcedural::Get ( const UsdStagePtr &  stage,
const SdfPath &  path 
)
static

Return a UsdProcGenerativeProcedural 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:

UsdProcGenerativeProcedural(stage->GetPrimAtPath(path));
USDPROC_API UsdAttribute UsdProcGenerativeProcedural::GetProceduralSystemAttr ( ) const

The name or convention of the system responsible for evaluating the procedural. NOTE: A fallback value for this is typically set via an API schema.

Declaration token proceduralSystem
C++ Type TfToken
Usd Type SdfValueTypeNames->Token
static USDPROC_API const TfTokenVector& UsdProcGenerativeProcedural::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.
