<p>This section of the user guide will be improved later. For now, the
following two presentations best describe how one can create data
objects or data files for Mayavi and TVTK.</p>
<blockquote>
<ul>
<li><p class="first">Presentation on TVTK and Mayavi2 for course at IIT Bombay</p>
<p><a class="reference" href="https://svn.enthought.com/enthought/attachment/wiki/MayaVi/tvtk_mayavi2.pdf">https://svn.enthought.com/enthought/attachment/wiki/MayaVi/tvtk_mayavi2.pdf</a></p>
<p>This presentation provides information on graphics in general, 3D
data representation, creating VTK data files, creating datasets
from numpy in Python, and also about mayavi.</p>
</li>
<li><p class="first">Presentation on making TVTK datasets using numpy arrays made for SciPy07.</p>
<p><a class="reference" href="https://svn.enthought.com/enthought/attachment/wiki/MayaVi/tvtk_datasets.pdf">https://svn.enthought.com/enthought/attachment/wiki/MayaVi/tvtk_datasets.pdf</a></p>
<p>This presentation focuses on creating TVTK datasets using numpy
arrays.</p>
</li>
</ul>
</blockquote>
<p>There are several examples in the mayavi sources that highlight the
creation of the most important datasets from numpy arrays. These may
be found in the <tt class="docutils literal"><span class="pre">examples</span></tt> directory. Specifically they are:</p>
<blockquote>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">polydata.py</span></tt>: Demonstrates how to create Polydata datasets
from numpy arrays and visualize them in mayavi.</li>
<li><tt class="docutils literal"><span class="pre">structured_points2d.py</span></tt>: Demonstrates how to create a 2D
structured points (or image data) dataset from numpy arrays and
visualize them in mayavi. This is basically a square of
equispaced points.</li>
<li><tt class="docutils literal"><span class="pre">structured_points3d.py</span></tt>: Demonstrates how to create a 3D
structured points (or image data) dataset from numpy arrays and
visualize them in mayavi. This is a cube of points that are
regularly spaced.</li>
<li><tt class="docutils literal"><span class="pre">structured_grid.py</span></tt>: Demonstrates the creation and
visualization of a 3D structured grid.</li>
<li><tt class="docutils literal"><span class="pre">unstructured_grid.py</span></tt>: Demonstrates the creation and
visualization of an unstructured grid.</li>
</ul>
</blockquote>
<p>These scripts may be run like so:</p>
<pre>$ mayavi2 -x structured_grid.py</pre>
<p>or better yet, all in one go like so:</p>
<pre>$ mayavi2 -x polydata.py -x structured_points2d.py \
> -x structured_points3d.py -x structured_grid.py -x unstructured_grid.py</pre>
