Difference between vertex and point in vtk
<p><strong>What's the main difference between a vertex and a point in <a href="http://www.vtk.org/" rel="noreferrer">VTK</a>?</strong></p>

<p>Well, I was assigning some computed points to an <a href="http://www.vtk.org/doc/nightly/html/classvtkPolyData.html" rel="noreferrer"><code>vtkPolyData</code></a> output:</p>

<pre><code>vtkPolyData* oput = vtkPolyData::SafeDownCast(out_info-&gt;Get(vtkDataObject::DATA_OBJECT()));
</code></pre>

<p>and I wondered whether to use the method <code>SetVerts(vtkCellArray *v)</code> or the method <code>SetPoints(vtkPoints *)</code>.</p>
