- paraview.simple.NetCDFReader(*input, **params)¶
arrays from NetCDF files into structured VTK data sets. In the absence of any other information, the files will be read as image data. This reader will also look for meta information specified by the CF convention that specify things like topology and time. This information can cause the output to be a nonuniform rectilinear grid or curvilinear (structured) grid. Details on the CF convention can be found at http://cf-pcmdi.llnl.gov/. It should be noted that the CF convention is a superset of the COARDS convention, so COARDS conventions will also be recognized.
Load the grid with the given dimensions. Any arrays that conform to these dimensions will be loaded.
The name of the files to load.
Specifies the type of data that the reader creates. If Automatic, the reader will use the most appropriate grid type for the data read. Note that not all grid types support all data. A warning is issued if a mismatch occurs.
If on, any float or double variable read that has a _FillValue attribute will have that fill value replaced with a not-a-number (NaN) value. The advantage of setting these to NaN values is that, if implemented properly by the system and careful math operations are used, they can implicitly be ignored by calculations like finding the range of the values. That said, this option should be used with caution as VTK does not fully support NaN values and therefore odd calculations may occur.
If on, then data with latitude/longitude dimensions will be read in as curvilinear data shaped like spherical coordinates. If false, then the data will always be read in Cartesian coordinates.
This magic property sends time information to the animation panel. ParaView will then automatically set up the animation to visit the time steps defined in the file.
The bias of the vertical component of spherical coordinates. It is common to write the vertical component with respect to something other than the center of the sphere (for example, the surface). In this case, it might be necessary to scale and/or bias the vertical height. The height will become height*scale + bias. Keep in mind that if the positive attribute of the vertical dimension is down, then the height is negated. The scaling will be adjusted if it results in invalid (negative) vertical values.

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
- __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)
