read#

read(filename, attrs=None, force_ext=None, file_format=None, progress_bar=False)[source]#

Read any file type supported by vtk or meshio.

Automatically determines the correct reader to use then wraps the corresponding mesh as a pyvista object. Attempts native vtk readers first then tries to use meshio.

Supports the following formats:

Standard dataset readers:

  • '.vtk'

  • '.pvtk'

  • '.vti'

  • '.pvti'

  • '.vtr'

  • '.pvtr'

  • '.vtu'

  • '.pvtu'

  • '.ply'

  • '.obj'

  • '.stl'

  • '.vtp'

  • '.vts'

  • '.vtm'

  • '.vtmb'

  • '.case'

Image formats:

  • '.bmp'

  • '.dem'

  • '.dcm'

  • '.img'

  • '.jpeg'

  • '.jpg'

  • '.mha'

  • '.mhd'

  • '.nrrd'

  • '.nhdr'

  • '.png'

  • '.pnm'

  • '.slc'

  • '.tiff'

  • '.tif'

Other formats:

  • '.byu'

  • '.g'

  • '.p3d'

  • '.pts'

  • '.tri'

  • '.inp'

Note

There is limited support for OpenFoam format files. pyvista.read will automatically return only the first dataset in a single-element pyvista.MultiBlock. These files include:

  • '.facet'

  • '.cas'

  • '.res'

  • '.foam'

Note

See https://github.com/nschloe/meshio for formats supported by meshio. Be sure to install meshio with pip install meshio if you wish to use it.

Parameters
filenamestr

The string path to the file to read. If a list of files is given, a pyvista.MultiBlock dataset is returned with each file being a separate block in the dataset.

attrsdict, optional

A dictionary of attributes to call on the reader. Keys of dictionary are the attribute/method names and values are the arguments passed to those calls. If you do not have any attributes to call, pass None as the value.

force_extstr, optional

If specified, the reader will be chosen by an extension which is different to its actual extension. For example, '.vts', '.vtu'.

file_formatstr, optional

Format of file to read with meshio.

progress_barbool, optional

Optionally show a progress bar. Default False. Ignored when using meshio.

Returns
pyvista.DataSet

Wrapped PyVista dataset.

Examples

Load an example mesh.

>>> import pyvista
>>> from pyvista import examples
>>> mesh = pyvista.read(examples.antfile)
>>> mesh.plot(cpos='xz')
../../../_images/pyvista-read-1_00_00.png

Load a vtk file.

>>> mesh = pyvista.read('my_mesh.vtk')  

Load a meshio file.

>>> mesh = pyvista.read("mesh.obj")
