<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>vtkPointSource is a source object that creates a user-specified number of points within a specified radius about a specified center point. By default location of the points is random within the sphere. It is also possible to generate random points only on the surface of the sphere.</p>
<p>To create an instance of class vtkPointSource, simply invoke its constructor as follows </p>
<pre class="fragment"> obj = vtkPointSource
</pre> <h1><a class="anchor" id="Methods"></a>
Methods</h1>
<p>The class vtkPointSource has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, <code>obj</code> is an instance of the vtkPointSource class. </p>
<ul>
<li>
<code>string = obj.GetClassName ()</code> </li>
<li>
<code>int = obj.IsA (string name)</code> </li>
<li>
<code>vtkPointSource = obj.NewInstance ()</code> </li>
<li>
<code>vtkPointSource = obj.SafeDownCast (vtkObject o)</code> </li>
<li>
<code>obj.SetNumberOfPoints (vtkIdType )</code> - Set the number of points to generate. </li>
<li>
<code>vtkIdType = obj.GetNumberOfPointsMinValue ()</code> - Set the number of points to generate. </li>
<li>
<code>vtkIdType = obj.GetNumberOfPointsMaxValue ()</code> - Set the number of points to generate. </li>
<li>
<code>vtkIdType = obj.GetNumberOfPoints ()</code> - Set the number of points to generate. </li>
<li>
<code>obj.SetCenter (double , double , double )</code> - Set the center of the point cloud. </li>
<li>
<code>obj.SetCenter (double a[3])</code> - Set the center of the point cloud. </li>
<li>
<code>double = obj. GetCenter ()</code> - Set the center of the point cloud. </li>
<li>
<code>obj.SetRadius (double )</code> - Set the radius of the point cloud. If you are generating a Gaussian distribution, then this is the standard deviation for each of x, y, and z. </li>
<li>
<code>double = obj.GetRadiusMinValue ()</code> - Set the radius of the point cloud. If you are generating a Gaussian distribution, then this is the standard deviation for each of x, y, and z. </li>
<li>
<code>double = obj.GetRadiusMaxValue ()</code> - Set the radius of the point cloud. If you are generating a Gaussian distribution, then this is the standard deviation for each of x, y, and z. </li>
<li>
<code>double = obj.GetRadius ()</code> - Set the radius of the point cloud. If you are generating a Gaussian distribution, then this is the standard deviation for each of x, y, and z. </li>
<li>
<code>obj.SetDistribution (int )</code> - Specify the distribution to use. The default is a uniform distribution. The shell distribution produces random points on the surface of the sphere, none in the interior. </li>
<li>
<code>obj.SetDistributionToUniform ()</code> - Specify the distribution to use. The default is a uniform distribution. The shell distribution produces random points on the surface of the sphere, none in the interior. </li>
<li>
<code>obj.SetDistributionToShell ()</code> - Specify the distribution to use. The default is a uniform distribution. The shell distribution produces random points on the surface of the sphere, none in the interior. </li>
<li>
<code>int = obj.GetDistribution ()</code> - Specify the distribution to use. The default is a uniform distribution. The shell distribution produces random points on the surface of the sphere, none in the interior. </li>
