Member Function Documentation

HDST_API void HdStPoints::_InitRepr	(	TfToken const &	reprToken,
		HdDirtyBits *	dirtyBits
	)

overrideprotectedvirtual

Initialize the given representation of this Rprim. This is called prior to syncing the prim, the first time the repr is used.

reprToken is the name of the representation to initalize.

dirtyBits is an in/out value. It is initialized to the dirty bits from the change tracker. InitRepr can then set additional dirty bits if additional data is required from the scene delegate when this repr is synced. InitRepr occurs before dirty bit propagation.

See HdRprim::InitRepr()

Implements HdRprim.

void HdStPoints::_PopulateVertexPrimvars	(	HdSceneDelegate *	sceneDelegate,
		HdRenderParam *	renderParam,
		HdStDrawItem *	drawItem,
		HdDirtyBits *	dirtyBitsState
	)

protected

HDST_API HdDirtyBits HdStPoints::_PropagateDirtyBits ( HdDirtyBits bits ) const

overrideprotectedvirtual

This callback from Rprim gives the prim an opportunity to set additional dirty bits based on those already set. This is done before the dirty bits are passed to the scene delegate, so can be used to communicate that extra information is needed by the prim to process the changes.

The return value is the new set of dirty bits, which replaces the bits passed in.

See HdRprim::PropagateRprimDirtyBits()

Implements HdRprim.

void HdStPoints::_UpdateRepr	(	HdSceneDelegate *	sceneDelegate,
		HdRenderParam *	renderParam,
		TfToken const &	reprToken,
		HdDirtyBits *	dirtyBitsState
	)

protected

HDST_API void HdStPoints::Finalize ( HdRenderParam * renderParam )

overridevirtual

Finalizes object resources. This function might not delete resources, but it should deal with resource ownership so that the rprim is deletable.

Reimplemented from HdRprim.

HDST_API HdDirtyBits HdStPoints::GetInitialDirtyBitsMask ( ) const

overridevirtual

Returns the set of dirty bits that should be added to the change tracker for this prim, when this prim is inserted.

Implements HdRprim.

HdStPoints::HF_MALLOC_TAG_NEW ( "new HdStPoints" )

HDST_API void HdStPoints::Sync	(	HdSceneDelegate *	delegate,
		HdRenderParam *	renderParam,
		HdDirtyBits *	dirtyBits,
		TfToken const &	reprToken
	)

overridevirtual

Pull invalidated scene data and prepare/update the renderable representation.

This function is told which scene data to pull through the dirtyBits parameter. The first time it's called, dirtyBits comes from _GetInitialDirtyBits(), which provides initial dirty state, but after that it's driven by invalidation tracking in the scene delegate.

The contract for this function is that the prim can only pull on scene delegate buffers that are marked dirty. Scene delegates can and do implement just-in-time data schemes that mean that pulling on clean data will be at best incorrect, and at worst a crash.

This function is called in parallel from worker threads, so it needs to be threadsafe; calls into HdSceneDelegate are ok.

Parameters

sceneDelegate	The data source for this geometry item.
renderParam	A render delegate object that holds rendering parameters that scene geometry may use.
dirtyBits	A specifier for which scene data has changed.
reprToken	The representation that needs to be updated. This is useful for backends that support multiple display representations for an rprim. A given representation may choose to pull on a subset of the dirty state.
dirtyBits	On input specifies which state is dirty and can be pulled from the scene delegate. On output specifies which bits are still dirty and were not cleaned by the sync.

Implements HdRprim.

HDST_API void HdStPoints::UpdateRenderTag	(	HdSceneDelegate *	delegate,
		HdRenderParam *	renderParam
	)

overridevirtual

Returns the identifier of this Rprim. This is both used in the RenderIndex and the SceneDelegate and acts as the associative key for the Rprim in both contexts.

Reimplemented from HdRprim.
