[Paraview] How to Read Transient Structured Data

[Kent Eschenberg]

I'm developing a new reader for ParaView 2.6.1 built upon 
vtkStructuredGridSource. It responds to pipeline requests via 
ExecuteInformation and ExecuteData.

How do I tell the pipeline about the time steps? The only existing 
reader I could find that uses vtkStructuredGridSource is vtkPLOT3DReader 
which does not seem to produce transient data.

I found another reader that is built on vtkUnstructuredGridAlgorithm 
that responds to pipeline requests via RequestInformation and 
RequestData. The RequestInformation arguments include

    vtkInformationVector *outputVector

that can be used to set vtkStreamingDemandDrivenPipeline::TIME_STEPS(). 
But there is no such argument for vtkStructuredGridSource's 
ExecuteInformation.

Suggestions?

TIA
