Member Function Documentation

void HdSceneIndexPluginRegistry::_CollectAdditionalMetadata ( const PlugRegistry &  plugRegistry, const TfType &  pluginType  )

overrideprotectedvirtual

Gives subclasses an opportunity to inspect plugInfo-based metadata at the time of discovery.

Reimplemented from HfPluginRegistry.

HD_API HdSceneIndexBaseRefPtr HdSceneIndexPluginRegistry::AppendSceneIndex	(	const TfToken &	sceneIndexPluginId,
		const HdSceneIndexBaseRefPtr &	inputScene,
		const HdContainerDataSourceHandle &	inputArgs
	)

Given a specific scene index plug-in id, give the plug-in a chance to add scene indices to the end of the chain. Return value is the last scene index – or inputScene if the plug-in chooses not to act. Input arguments may be nullptr if not relevant to this plug-in.

HD_API HdSceneIndexBaseRefPtr HdSceneIndexPluginRegistry::AppendSceneIndicesForRenderer	(	const std::string &	rendererDisplayName,
		const HdSceneIndexBaseRefPtr &	inputScene,
		const std::string &	renderInstanceId = std::string()
	)

Append scene indices generated by plug-ins registered (via RegisterSceneIndexForRenderer) for this renderer. Return value is the last scene index – or inputScene if no plugins are registered or taking action. This also includes plug-ins registered for all renderers (via an empty rendererDisplayName) to be added in advance of any registered for the specified rendeer.

template<typename T , typename... Bases>

void HdSceneIndexPluginRegistry::Define ( )

static

Entry point for defining an HdSceneIndexPlugin plugin.

Definition at line 200 of file sceneIndexPluginRegistry.h.

static HD_API HdSceneIndexPluginRegistry& HdSceneIndexPluginRegistry::GetInstance ( )

static

Returns the singleton registry for HdSceneIndexPlugin

HD_API void HdSceneIndexPluginRegistry::RegisterSceneIndexForRenderer	(	const std::string &	rendererDisplayName,
		const TfToken &	sceneIndexPluginId,
		const HdContainerDataSourceHandle &	inputArgs,
		InsertionPhase	insertionPhase,
		InsertionOrder	insertionOrder
	)

Register a scene index to be instantiated for a specified renderer (or all renderers if rendererDisplayName is empty).

Insertion phase is a broad ordering value with lower values indicating earlier instantiation (possibly given render plugin-specific meaning via enum values). Insertion order indicates whether this entry should go at the start or end of the specified phase.

HD_API void HdSceneIndexPluginRegistry::RegisterSceneIndexForRenderer	(	const std::string &	rendererDisplayName,
		SceneIndexAppendCallback	callback,
		const HdContainerDataSourceHandle &	inputArgs,
		InsertionPhase	insertionPhase,
		InsertionOrder	insertionOrder
	)

Register a scene index to be instantiated via a callback for a specified renderer (or all renderers if rendererDisplayName is empty).

This is most useful for application-specific behavior which wants to append and manage scene index instances associated with a specific render. To aid in that association, the callback is provided a renderInstanceId value typically defined by the application itself.

Insertion phase is a broad ordering value with lower values indicating earlier instantiation (possibly given render plugin-specific meaning via enum values). Insertion order indicates whether this entry should go at the start or end of the specified phase.

Note

This method should be invoked before render index construction when Hydra scene index emulation is enabled.
