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

vtkCityGMLReader is a reader for CityGML .gml files. The output is a multiblock dataset. We read objects at level of detail (LOD) specified (default is 3). The leaves of the multiblock dataset (which are polygonal datasets) have a field array with one element called “gml_id” which corresponds to the gml:id for gml:TriangulatedSurface, gml:MultiSurface or gml:CompositeSurface in the CityGML file. If the polygonal dataset has a texture, we specify this with a point array called “tcoords” and a field array with one element called “texture_uri” containing the path to the texture file. Top level children of the multiblock dataset have a field array with one element called “element” which contains the CityGML element name for example: dem:ReliefFeature, wtr:WaterBody, grp::CityObjectGroup (forest), veg:SolitaryVegetationObject, brid:Bridge, run:Tunel, tran:Railway, tran:Road, bldg:Building, gen:GenericCityObject, luse:LandUse

Data Descriptors


Reads buildings between [BeginBuildingIndex, EndBuildingIndex) in the file.


Reads buildings between [BeginBuildingIndex, EndBuildingIndex) in the file.


Specify file name of the CityGML data file to read.


Specify the level of detail (LOD) to read. Valid values are from 0 (least detailed) through 4 (most detailed), default value is 3.


Number of buildings to read from the file.


Certain input files use app:transparency as opacity. Set this field true to show that correctly. The default is false.

Data Descriptors inherited from Proxy


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)
