Detailed Description

The UsdImagingGeomXformVectorsSchema exposes the result of UsdGeomXformCommonAPI::GetXformVectorsByAccumulation().

This is a decomposition of the USD transformation operations that includes more information than is available in the xform matrix value, such as the pivot offset. This schema is intended for read-only access to data stored in USD; it is otherwise inert and does not participate in or imply any subsequent computations.

Member Function Documentation

BuildRetained()

static USDIMAGING_API HdContainerDataSourceHandle BuildRetained ( const HdVec3dDataSourceHandle &  translation, const HdVec3fDataSourceHandle &  rotation, const HdTokenDataSourceHandle &  rotationOrder, const HdVec3fDataSourceHandle &  scale, const HdVec3fDataSourceHandle &  pivot  )

static

Deprecated:

Use Builder instead.

Builds a container data source which includes the provided child data sources. Parameters with nullptr values are excluded. This is a low-level interface. For cases in which it's desired to define the container with a sparse set of child fields, the Builder class is often more convenient and readable.

GetDefaultLocator()

static USDIMAGING_API const HdDataSourceLocator & GetDefaultLocator ( )

static

Returns an HdDataSourceLocator (relative to the prim-level data source) where the container representing this schema is found by default.

GetFromParent()

static USDIMAGING_API UsdImagingGeomXformVectorsSchema GetFromParent ( const HdContainerDataSourceHandle &  fromParentContainer )

static

Retrieves a container data source with the schema's default name token "geomXformVectors" from the parent container and constructs a UsdImagingGeomXformVectorsSchema instance.

Because the requested container data source may not exist, the result should be checked with IsDefined() or a bool comparison before use.

GetSchemaToken()

static USDIMAGING_API const TfToken & GetSchemaToken ( )

static

Returns a token where the container representing this schema is found in a container by default.
