<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>The class serves as an abstract geometrical representation for the vtkTensorProbeWidget. It is left to the concrete implementation to render the tensors as it desires. For instance, vtkEllipsoidTensorProbeRepresentation renders the tensors as ellipsoids.</p>
<p>To create an instance of class vtkTensorProbeRepresentation, simply invoke its constructor as follows </p>
<pre class="fragment"> obj = vtkTensorProbeRepresentation
</pre> <h1><a class="anchor" id="Methods"></a>
Methods</h1>
<p>The class vtkTensorProbeRepresentation 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 vtkTensorProbeRepresentation class. </p>
<ul>
<li>
<code>string = obj.GetClassName ()</code> - Standard methods for instances of this class. </li>
<li>
<code>int = obj.IsA (string name)</code> - Standard methods for instances of this class. </li>
<li>
<code>vtkTensorProbeRepresentation = obj.NewInstance ()</code> - Standard methods for instances of this class. </li>
<li>
<code>vtkTensorProbeRepresentation = obj.SafeDownCast (vtkObject o)</code> - Standard methods for instances of this class. </li>
<li>
<code>obj.BuildRepresentation ()</code> - See vtkWidgetRepresentation for details. </li>
<li>
<code>int = obj.RenderOpaqueGeometry (vtkViewport )</code> - See vtkWidgetRepresentation for details. </li>
<li>
<code>obj.SetProbePosition (double , double , double )</code> - Set the position of the Tensor probe. </li>
<li>
<code>obj.SetProbePosition (double a[3])</code> - Set the position of the Tensor probe. </li>
<li>
<code>double = obj. GetProbePosition ()</code> - Set the position of the Tensor probe. </li>
<li>
<code>obj.SetProbeCellId (vtkIdType )</code> - Set the position of the Tensor probe. </li>
<li>
<code>vtkIdType = obj.GetProbeCellId ()</code> - Set the position of the Tensor probe. </li>
<li>
<code>obj.SetTrajectory (vtkPolyData )</code> - Set the trajectory that we are trying to probe tensors on </li>
<li>
<code>obj.Initialize ()</code> - Set the probe position to a reasonable location on the trajectory. </li>
<li>
<code>int = obj.SelectProbe (int pos[2])</code> - This method is invoked by the widget during user interaction. Can we pick the tensor glyph at the current cursor pos </li>
<li>
<code>int = obj.Move (double motionVector[2])</code> - INTERNAL - Do not use This method is invoked by the widget during user interaction. Move probe based on the position and the motion vector. </li>
<li>
<code>obj.GetActors (vtkPropCollection )</code> - See vtkProp for details. </li>
<li>
<code>obj.ReleaseGraphicsResources (vtkWindow )</code> - See vtkProp for details. </li>
