Re: [Paraview] Can ParaView create "envelope" or cumulative maximums?
Somebody kindly defined a variable called "request" in the programmable
filter. So you can do:
request.Set(vtk.vtkStreamingDemandDrivenPipeline.CONTINUE_EXECUTING(), 1)
I believe.

Jean,
Manipulating time inside pipeline objects is explained pretty well here:

Subject: [Paraview] Re: Can ParaView create "envelope" or cumulative maximums
Alan,
My first thought is to run Temporal Statistics with Maximum selected and paint
by that. Is that not working?
Dennis
Incidentally, I tried to achieve this with a Python programmable filter since
that was Alan's question.
I did not succeed. I am removing the TIME_STEPS() and TIME_RANGE() in the
RequestInformationScript script. I am setting a different UPDATE_TIME_STEP() at
each iteration of the RequestUpdateExtentScript. I am setting
CONTINUE_EXECUTING() in the main Script, but ParaView just does not loop after
the first iteration.
I have the feeling I am not setting CONTINUE_EXECUTING on the right object.
Question:
how does one get the request object from the executive? When I look at C code, I
see
int vtkTemporalStatistics::RequestData(vtkInformation *request,
vtkInformationVector **inputVector, vtkInformationVector *outputVector) { ...
request->Set(vtkStreamingDemandDrivenPipeline::CONTINUE_EXECUTING(), 1) ... }
What is the equivalent in Python within a ProgrammableFilter()?

[Paraview] Can ParaView create "envelope" or cumulative maximums?
I have a user that needs to create a new array, with each cell in the array holding the maximum value of each cell over all time. I have heard this called a cumulative maximum for all cells. The then wants to paint his 3d object with this new array. For instance, if you have a variable array (maybe von mises stress), three cells and four timesteps, as follows: Three cells: 0.0 0.0 0.0(Timestep 0) 1.0 0.0 0.0(Timestep 1) 2.0 1.0 0.0(Timestep 2) 1.0 3.0 1.0(Timestep 3) Results, to be used to paint the object in a 3d view: 2.0 3.0 1.0(Result) Does anyone know how to do this? My user feels comfortable with Python and the Programmable filter/ Python Calculator.
