<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>vtkPolyVertex is a concrete implementation of vtkCell to represent a set of 3D vertices.</p>
<p>To create an instance of class vtkPolyVertex, simply invoke its constructor as follows </p>
<pre class="fragment"> obj = vtkPolyVertex
</pre> <h1><a class="anchor" id="Methods"></a>
Methods</h1>
<p>The class vtkPolyVertex 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 vtkPolyVertex class. </p>
<ul>
<li>
<code>string = obj.GetClassName ()</code> </li>
<li>
<code>int = obj.IsA (string name)</code> </li>
<li>
<code>vtkPolyVertex = obj.NewInstance ()</code> </li>
<li>
<code>vtkPolyVertex = obj.SafeDownCast (vtkObject o)</code> </li>
<li>
<code>int = obj.GetCellType ()</code> - See the vtkCell API for descriptions of these methods. </li>
<li>
<code>int = obj.GetCellDimension ()</code> - See the vtkCell API for descriptions of these methods. </li>
<li>
<code>int = obj.GetNumberOfEdges ()</code> - See the vtkCell API for descriptions of these methods. </li>
<li>
<code>int = obj.GetNumberOfFaces ()</code> - See the vtkCell API for descriptions of these methods. </li>
<li>
<code>vtkCell = obj.GetEdge (int )</code> - See the vtkCell API for descriptions of these methods. </li>
<li>
<code>vtkCell = obj.GetFace (int )</code> - See the vtkCell API for descriptions of these methods. </li>
<li>
<code>int = obj.CellBoundary (int subId, double pcoords[3], vtkIdList pts)</code> - See the vtkCell API for descriptions of these methods. </li>
<li>
<code>obj.Contour (double value, vtkDataArray cellScalars, vtkIncrementalPointLocator locator, vtkCellArray verts, vtkCellArray lines, vtkCellArray polys, vtkPointData inPd, vtkPointData outPd, vtkCellData inCd, vtkIdType cellId, vtkCellData outCd)</code> - See the vtkCell API for descriptions of these methods. </li>
<li>
<code>obj.Clip (double value, vtkDataArray cellScalars, vtkIncrementalPointLocator locator, vtkCellArray verts, vtkPointData inPd, vtkPointData outPd, vtkCellData inCd, vtkIdType cellId, vtkCellData outCd, int insideOut)</code> - See the vtkCell API for descriptions of these methods. </li>
<li>
<code>int = obj.Triangulate (int index, vtkIdList ptIds, vtkPoints pts)</code> - See the vtkCell API for descriptions of these methods. </li>
<li>
<code>obj.Derivatives (int subId, double pcoords[3], double values, int dim, double derivs)</code> - See the vtkCell API for descriptions of these methods. </li>
<li>
<code>int = obj.IsPrimaryCell ()</code> - Return the center of the point cloud in parametric coordinates. </li>
<li>
<code>int = obj.GetParametricCenter (double pcoords[3])</code> - Return the center of the point cloud in parametric coordinates. </li>
<li>
<code>obj.InterpolateFunctions (double pcoords[3], double weights)</code> - Compute the interpolation functions/derivatives (aka shape functions/derivatives) </li>
<li>
<code>obj.InterpolateDerivs (double pcoords[3], double derivs)</code> - Compute the interpolation functions/derivatives (aka shape functions/derivatives) </li>
