paraview.simple.TableFFT

paraview.simple.TableFFT(*input, **params)

Performs the Fast Fourier Transform on the columns of a table.

Data Descriptors

AverageFFTperblock

Specify if the input should be split in multiple blocks to compute an average fft across all blocks.

BlockSize

Specify the number of samples to use for each block. This should be a power of 2. If not, the closest power of two will be used anyway.

CreateFrequencyColumn

Specify if the filter should create a frequency column based on a column named “time” (not case sensitive). An evenly-spaced time array is expected.

Input

This property specifies the input to the filter.

Normalize

Specify if the output should be normalized.

NumberOfBlock

Specify the number of blocks to use when computing the average fft over the whole input sample array. If NumberOfBlock == 1, no average is done and we only compute the fft on the first BlockSize samples of the input data.

OptimizeForRealInput

Specify if the filter should use the optimized discrete fourier transform for real values. This will cause output columns to have from n to ((n / 2) + 1) rows.

WindowingFunction

Specify the windowing function to apply on the input. This allows to better process data that is not periodic. When NumberOfBlocks > 1, the windowing function is applied to each block.

Methods

Initialize = aInitialize(self, connection=None, update=True)

Methods inherited from SourceProxy

FileNameChanged(self)

Called when the filename of a source proxy is changed.

GetCellDataInformation(self)

Returns the associated cell data information.

GetDataInformation(self, idx=None)

This method returns a DataInformation wrapper around a vtkPVDataInformation

GetFieldDataInformation(self)

Returns the associated cell data information.

GetPointDataInformation(self)

Returns the associated point data information.

UpdatePipeline(self, time=None)

This method updates the server-side VTK pipeline and the associated data information. Make sure to update a source to validate the output meta-data.

UpdatePipelineInformation(self)

This method updates the meta-data of the server-side VTK pipeline and the associated information properties

__getitem__(self, idx)

Given a slice, int or string, returns the corresponding output port

Methods inherited from Proxy

GetProperty(self, name)

Given a property name, returns the property object.

GetPropertyValue(self, name)

Returns a scalar for properties with 1 elements, the property itself for vectors.

InitializeFromProxy(self, aProxy, update=True)

Constructor. Assigns proxy to self.SMProxy, updates the server object as well as register the proxy in _pyproxies dictionary.

ListProperties(self)

Returns a list of all property names on this proxy.

SetPropertyWithName(self, pname, arg)

Generic method for setting the value of a property.

__del__(self)

Destructor. Cleans up all observers as well as remove the proxy from the _pyproxies dictionary

__eq__(self, other)

Returns true if the underlying SMProxies are the same.

__getattr__(self, name)

With the exception of a few overloaded methods, returns the SMProxy method

__hash__(self)

Return hash(self).

__init__(self, **args)

Default constructor. It can be used to initialize properties by passing keyword arguments where the key is the name of the property. In addition registrationGroup and registrationName (optional) can be specified (as keyword arguments) to automatically register the proxy with the proxy manager.

__iter__(self)

Creates an iterator for the properties.

__ne__(self, other)

Returns false if the underlying SMProxies are the same.

__setattr__(self, name, value)

Implement setattr(self, name, value).

add_attribute(self, name, value)
