<a href="http://paraview.org">ParaView</a> and its Python API <code>pvpython</code>.</p>
<p>This website is targeting novice users who are not power users of <a href="http://paraview.org">ParaView</a> but who would like to get started with topological data analysis with <a href="https://topology-tool-kit.github.io/">TTK</a> in Python.</p>
<p>Each example includes:</p>
<ul>
<li>a screenshot (or a tutorial video)</li>
<li>a short description</li>
<li>the command line to reproduce the example with <a href="http://paraview.org">ParaView</a></li>
<li>the corresponding Python code, to:<ul>
<li>load the input data </li>
<li>execute the analysis pipeline</li>
<li>store the output to disk (for later analysis or visualization, e.g. with <a href="http://paraview.org">ParaView</a>)</li>
</ul>
</li>
<li>a description of the inputs and outputs</li>
<li>pointers to the corresponding C++/Python documentation</li>
</ul>
<p>This documentation assumes a default installation of the latest version of TTK (with the <code>pvpython</code> API support enabled) and that the repository <a href="https://github.com/topology-tool-kit/ttk-data">ttk-data</a> has been downloaded locally.</p>
<p>If you have any questions regarding these examples, please let us know by sending an email to the <a href="mailto:ttk-users@googlegroups.com">TTK user mailing list</a>!</p>
