<h2>Introduction</h2>

<p>
PyVTK provides the following tools for manipulating <a
href="http://www.kitware.com/">Visualization Toolkit (VTK)</a> files in Python:

<dl>
  <dt>VtkData
  <dd>Create VTK file from Python objects. It fully
      supports <a href="http://www.vtk.org/pdf/file-formats-2.2.pdf">VTK
      File Formats Standard 2.0</a>
      (see also <a href="http://www.vtk.org/pdf/file-formats.pdf">VTK
      File Formats Standard 3.0</a>).
      The features include:
      <ul>
	<li>ascii and binary output, ascii input from VTK file
	<li>DataSet formats:
	    StructuredPoints, StructuredGrid, RectilinearGrid,
	    PolyData, UnstructuredGrid
	<li>Data formats:
                 PointData, CellData
	<li>DataSetAttr formats:
	    Scalars, ColorScalars, LookupTable, Vectors, 
	    Normals, TextureCoordinates, Tensors, Field
      </ul>
</dl>
