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

This probes a point cloud PC on the Input with a set of points P (the filter Source), interpolating the data values from PC onto P. Note however that the descriptive phrase “point cloud” is a misnomer: PC can be represented by any dataset type, with the points of the dataset forming PC. Similarly, the output P can also be represented by any vtkDataSet type; and the topology/geometry structure of P is passed through to the output along with the newly interpolated arrays.

Data Descriptors


The data source to be interpolated onto the *Source*.


Specify an interpolation kernel. By default a vtkVoronoiKernel is used (i.e., closest point). The interpolation kernel changes the basis of the interpolation.


Specify a point locator.


Specify a strategy to use when encountering a “null” point during the interpolation process. Null points occur when the local neighborhood (of nearby points to interpolate from) is empty. If the strategy is set to MaskPoints, then an output array is created that marks points as being valid (=1) or null (invalid =0) (and the NullValue is set as well). If the strategy is set to NullValue, then the output data value(s) are set to the NullPoint value (specified in the output point data). Finally, the default strategy ClosestPoint is to simply use the closest point to perform the interpolation.


Specify the null point value. When a null point is encountered then all components of each null tuple are set to this value. By default the null value is set to zero.


Indicate whether to shallow copy the input cell data arrays to the output.


Indicate whether to shallow copy the input field data arrays to the output.


Indicate whether to shallow copy the input point data arrays to the output.


If the NullPointsStrategy is “Mask Points”, then an array is generated for each input point. This vtkCharArray is placed into the output of the filter, with a non-zero value for a valid point, and zero otherwise. The name of this masking array is specified here.

dictionary for instance variables (if defined)


list of weak references to the object (if defined)


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

Methods inherited from SourceProxy


Called when the filename of a source proxy is changed.


Returns the associated cell data information.

GetDataInformation(self, idx=None)

This method returns a DataInformation wrapper around a vtkPVDataInformation


Returns the associated cell data information.


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.


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.


Returns a list of all property names on this proxy.

SetPropertyWithName(self, pname, arg)

Generic method for setting the value of a property.


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


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.


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)
