<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>vtkRTAnalyticSource just produces images with pixel values determined by a Maximum*Gaussian*XMag*sin(XFreq*x)*sin(YFreq*y)*cos(ZFreq*z) Values are float scalars on point data with name "RTData".</p>
<p>To create an instance of class vtkRTAnalyticSource, simply invoke its constructor as follows </p>
<pre class="fragment"> obj = vtkRTAnalyticSource
</pre> <h1><a class="anchor" id="Methods"></a>
Methods</h1>
<p>The class vtkRTAnalyticSource 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 vtkRTAnalyticSource class. </p>
