paraview.simple.TensorGlyph

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

The Tensor Glyph filter generates an ellipsoid, cuboid, cylinder or superquadric glyph at every point in the input data set. The glyphs are oriented and scaled according to eigenvalues and eigenvectors of tensor point data of the input data set. The Tensor Glyph filter operates on any type of data set. Its output is polygonal. This filter supports symmetric tensors. Symmetric tensor components are expected to have the following order: XX, YY, ZZ, XY, YZ, XZ”

Data Descriptors

ColorGlyphs

This property determines whether or not to color the glyphs.

Colorby

This property determines whether input scalars or computed eigenvalues at the point should be used to color the glyphs. If ThreeGlyphs is set and the eigenvalues are chosen for coloring then each glyph is colored by the corresponding eigenvalue and if not set the color corresponding to the largest eigenvalue is chosen.

ExtractEigenvalues

Toggle whether to extract eigenvalues from tensor. If false, eigenvalues/eigenvectors are not extracted and the columns of the tensor are taken as the eigenvectors (the norm of column, always positive, is the eigenvalue). If true, the glyph is scaled and oriented according to eigenvalues and eigenvectors; additionally, eigenvalues are provided as new data array.

GlyphType

This property determines which type of glyph will be placed at the points in the input dataset.

Input

This property specifies the input to the Glyph filter.

LimitScalingByEigenvalues

This property determines whether scaling of glyphs by ScaleFactor times eigenvalue should be limited. This is useful to prevent uncontrolled scaling near singularities.

MaxScaleFactor

If scaling by eigenvalues should be limited, this value sets an upper limit for scale factor times eigenvalue.

Scalars

This property indicates the name of the scalar array to use for coloring

ScaleFactor

This property specifies the scale factor to scale every glyph by.

Symmetric

This property determines whether or not to draw a mirror of each glyph.

Tensors

This property indicates the name of the tensor array on which to operate. The indicated array’s eigenvalues and eigenvectors are used for scaling and orienting the glyphs.

ThreeGlyphs

Toggle whether to produce three glyphs, each of which oriented along an eigenvector and scaled according to the corresponding eigenvector.

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)
