Detailed Description

Provide a base API for a emulated real time LiveSource.

This class is intended to be inherited by a temporal algorithm. It allows the algorithm to be updated at regular time intervals, using ParaView LiveSource concept, while also seamlessly functioning with standard vtk animation sequences.

An use case to use this class would be is to replicate the behavior of a LiveSource which has been recorded in a file. It's important to note that time in this context is measured in seconds.

The inherited class should then be defined as a LiveSource in its XML definition, as shown below:

<Hints>
   <LiveSource interval="100" emulated_time="1" />
 </Hints>

If the pipeline process is taking more time that the timesteps gap, it will skip frames.

◆ GetNeedsUpdate()

virtual bool vtkEmulatedTimeAlgorithm::GetNeedsUpdate ( double time )

virtual

Check whether the provided time falls within the algorithm TimeRange, if it does return true to update the source with the new time.

Also save the current time steps asked by the LiveSource behavior, enabling it to invoke RequestData for the specified time through the RequestUpdateExtent method.

Required for LiveSource behavior.

◆ Modified()

void vtkEmulatedTimeAlgorithm::Modified ( )

overridevirtual

LiveSources algorithm requires calling this->Modified() to update the data.

However, doing so triggers an unwanted call to RequestInformation. To address this, we override the standard Modified method to ensure that RequestInformation is only invoked when the parameters are actually modified.

Reimplemented from vtkObject.

◆ GetTimeRange() [1/3]

◆ ProcessRequest()

vtkTypeBool vtkEmulatedTimeAlgorithm::ProcessRequest	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)

overridevirtual

Process a request from the executive.

For vtkEmulatedTimeAlgorithm, the request will be delegated to one of the following methods: RequestData, RequestInformation or RequestUpdateExtent.

If the request ask for REQUEST_INFORMATION(), it invokes the subclass's RequestInformation method. It copies then the time range and time steps to be able to interact with the LiveSource behavior.

See vtkAlgorithm for more details.

Reimplemented from vtkAlgorithm.

◆ RequestInformation()

virtual int vtkEmulatedTimeAlgorithm::RequestInformation	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)

protectedpure virtual

This is called within ProcessRequest.

It is a method you need to override, it should provide information about its output without doing any lengthy computations.

It is expected that the overriden method set time information such as TIME_STEPS() and TIME_RANGE().

◆ RequestData()

virtual int vtkEmulatedTimeAlgorithm::RequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)

protectedpure virtual

This is called within ProcessRequest when a request asks the algorithm to do its work.

It is a method you need to override, to do whatever the algorithm is designed to do. This happens during the final pass in the pipeline execution process.

◆ RequestUpdateExtent()

virtual int vtkEmulatedTimeAlgorithm::RequestUpdateExtent	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)

protectedvirtual

If an update is needed from the LiveSource behavior, update the current pipeline timestep.

Otherwise do nothing.
