Detailed Description

A prim data source providing resolved data for a points based prim (mesh, basisCurves, points) deformed by a skeleton. As a data source, it populates the HdExtComputationPrimvarsSchema for points and possibly for normals and removes points and normals from the HdPrimvarsSchema.

Used by the UsdSkelImagingPointsResolvingSceneIndex in conjunction with the UsdSkelImagingDataSourceResolvedExtComputationPrim.

Member Function Documentation

USDSKELIMAGING_API HdDataSourceBaseHandle UsdSkelImagingDataSourceResolvedPointsBasedPrim::Get ( const TfToken &  name)
overridevirtual

Returns the child datasource of the given name. This call is expected to be threadsafe.

Implements HdContainerDataSource.

USDSKELIMAGING_API std::shared_ptr<UsdSkelImagingBlendShapeData> UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetBlendShapeData ( )

Blend shape data computed from primvars, skel bindings and skeleton.

USDSKELIMAGING_API HdDataSourceBaseHandle UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetBlendShapeOffsetRanges ( )
USDSKELIMAGING_API HdDataSourceBaseHandle UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetBlendShapeOffsets ( )
const VtArray<SdfPath>& UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetBlendShapeTargetPaths ( ) const

USDSKELIMAGING_API HdFloatArrayDataSourceHandle UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetBlendShapeWeights ( )
USDSKELIMAGING_API HdMatrixDataSourceHandle UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetCommonSpaceToPrimLocal ( ) const

Transfrom to go from common space (as defined by UsdSkelImagingDataSourceXformResolver) to the local space of this prim.

static USDSKELIMAGING_API const HdDataSourceLocatorSet& UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetDependendendOnDataSourceLocators ( )
static

Data source locators (on this prim) that this prim depends on.

That is, if the input scene sends a dirty entry for this prim path with dirty locators intersecting these data source locators, we need to call ProcessDirtyLocators.

(Similar to dependendedOnDataSourceLocator in HdDependencySchema).

const VtArray<SdfPath>& UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetInstancerPaths ( ) const
inline

Paths to instancers instancing this prim - not including ones outside the skel root.

See UsdSkelImagingDataSourceXformResolver for details.

Definition at line 87 of file dataSourceResolvedPointsBasedPrim.h.

USDSKELIMAGING_API std::shared_ptr<UsdSkelImagingJointInfluencesData> UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetJointInfluencesData ( )

Joint influences data computed from primvars.

USDSKELIMAGING_API TfTokenVector UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetNames ( )
overridevirtual

Returns the list of names for which Get(...) is expected to return a non-null value. This call is expected to be threadsafe.

Definition at line 72 of file dataSourceResolvedPointsBasedPrim.h.

const HdPrimvarsSchema& UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetPrimvars ( ) const
inline

Primvars of prim in the input scene.

Definition at line 92 of file dataSourceResolvedPointsBasedPrim.h.

const UsdSkelImagingResolvedSkeletonSchema& UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetResolvedSkeletonSchema ( )
inline

Resolved skeleton of prim in the input scene.

const TfToken& UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetSkinningMethod ( ) const
inline

Skinning method computed from corresponding primvar.

Definition at line 161 of file dataSourceResolvedPointsBasedPrim.h.

USDSKELIMAGING_API HdMatrix3fArrayDataSourceHandle UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetSkinningScaleTransforms ( )

Only valid if GetSkinningMethod() == UsdSkelTokens->dualQuaternion.

USDSKELIMAGING_API HdMatrix4fArrayDataSourceHandle UsdSkelImagingDataSourceResolvedPointsBasedPrim::GetSkinningTransforms ( )
bool UsdSkelImagingDataSourceResolvedPointsBasedPrim::HasExtComputations ( ) const

Should the points for this primvar be given by an ext computation or from the primvars schema.

bool UsdSkelImagingDataSourceResolvedPointsBasedPrim::HasNormalsExtComputations ( ) const

Should the normals for this primvar be given by an ext computation.

UsdSkelImagingDataSourceResolvedPointsBasedPrim::HD_DECLARE_DATASOURCE ( UsdSkelImagingDataSourceResolvedPointsBasedPrim  )
static USDSKELIMAGING_API Handle UsdSkelImagingDataSourceResolvedPointsBasedPrim::New ( HdSceneIndexBaseRefPtr const &  sceneIndex,
SdfPath  primPath,
HdContainerDataSourceHandle  primSource 
)
static

C'tor.

Note that it takes the data source for the prim at primPath in the given sceneIndex. This is for performance: the client probably already retrieved this data source so we want to avoid looking it up again here.

Returns a nullptr if there the prim in the input scene does not bind a skeleton.

USDSKELIMAGING_API bool UsdSkelImagingDataSourceResolvedPointsBasedPrim::ProcessDirtyLocators ( const TfToken &  dirtiedPrimType,
const HdDataSourceLocatorSet &  dirtyLocators,
HdSceneIndexObserver::DirtiedPrimEntries *  entries 
)

Dirty internal structures in response to dirty locators for the target (resolved) skeleton prim (dirtiedPrimType = "skeleton"), a targeted skelBlendShape prim (dirtiedPrimType = "skelBlendShape") or the prim in the input scene itself (any other dirtiedPrimType). Fills dirtied prim entries with affected locators for this prim or returns true to indicate that we could not dirty this data source and need to refetch it.
