paraview.simple.__init__.QuadricDecimation

paraview.simple.__init__.QuadricDecimation(*input, **params)

Reduce the number of triangles in a triangle mesh, forming a good approximation to the original geometry. Only triangles are treated. To decimate polygonal meshes, first triangulate the polygons with Triangulate.

Data Descriptors

AttributeErrorMetric

Decide whether to include data attributes in the error metric. If off, then only geometric error is used to control the decimation.

Input

MapPointData

Keep point data to the output during decimation.

NormalsAttribute

This flag controls whether normals attributes are to be included in the error calculation.

NormalsWeight

Scaling weight contribution of the normal attribute. This value is used to weight the contribution of the normal attribute towards the error metric.

Regularization

Adjust the level of regularization. Help to have better quality mesh elements at the cost of lower precision on the geometry.

Regularize

Boolean property determining whether or not to use the regularization method.

ScalarsAttribute

This flag controls whether scalars attributes are to be included in the error calculation.

ScalarsWeight

Scaling weight contribution of the scalar attribute. This value is used to weight the contribution of the scalar attribute towards the error metric.

TCoordsAttribute

This flag controls whether texture coordinates attributes are to be included in the error calculation.

TCoordsWeight

Scaling weight contribution of the texture coordinates attribute. This value is used to weight the contribution of the texture coordinates attribute towards the error metric.

TargetReduction

Desired reduction (expressed as a fraction of the original number of triangles). The actual reduction may be less depending on triangulation and topological constraints.

TensorsAttribute

This flag controls whether tensors attributes are to be included in the error calculation.

TensorsWeight

Scaling weight contribution of the tensors attribute. This value is used to weight the contribution of the tensors attribute towards the error metric.

VectorsAttribute

This flag controls whether vectors attributes are to be included in the error calculation.

VectorsWeight

Scaling weight contribution of the vector attribute. This value is used to weight the contribution of the vector attribute towards the error metric.

VolumePreservation

Decide whether to activate volume preservation which greatly reduces errors in triangle normal direction. If off, volume preservation is disabled and if AttributeErrorMetric is active, these errors can be large.

Methods

Initialize = aInitialize(self, connection=None, update=True) from paraview.servermanager._createInitialize.<locals>

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.

GetInformation(self)

GetPointDataInformation(self)

Returns the associated point data information.

Rename(self, new_name)

Rename proxy in GUI

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.

Set(self, **properties)

Update a set of properties using a keyword argument notation

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

__enter__(self)

Activate proxy if possible

__eq__(self, other)

Returns true if the underlying SMProxies are the same.

__exit__(self, exc_type, exc_value, traceback)

Revert previously activated proxy

__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)
