Suneet,<br>
have a look at the Graphics/Testing/Tcl/shepards.tcl example (or click <a href="http://public.kitware.com/cgi-bin/viewcvs.cgi/*checkout*/Graphics/Testing/Tcl/shepards.tcl?root=VTK&content-type=text/plain">here</a>).
You will see that vtkShepardMethod is fed a vtkPolyData instance which,
in turn, "contains" the vtkPoints instance. The example shows how to
properly set up the pipeline.<br>
<br>
Best regards<br>

<br>
</span></font></p>
<p><font size="2" color="navy" face="Verdana"><span style="font-size: 10pt; font-family: Verdana; color: navy;">I am trying to convert a grid of
unstructured points in to structured data. I saw that VTK has a method
vtkShepardMethod() to do this. </span></font></p>
<p><font size="2" color="navy" face="Verdana"><span style="font-size: 10pt; font-family: Verdana; color: navy;">Does anyone have an example of how to
accomplish this? </span></font></p>
<p><font size="2" color="navy" face="Verdana"><span style="font-size: 10pt; font-family: Verdana; color: navy;"> </span></font></p>
<p><font size="2" color="navy" face="Verdana"><span style="font-size: 10pt; font-family: Verdana; color: navy;">I created a point array </span></font></p>
<p><font size="2" color="navy" face="Verdana"><span style="font-size: 10pt; font-family: Verdana; color: navy;">vtkDotNetWrap::vtkPoints points =
vtkDotNetWrap::vtkPoints::New();</span></font></p>

<p><font size="2" color="navy" face="Verdana"><span style="font-size: 10pt; font-family: Verdana; color: navy;">}</span></font></p>
<p><font size="2" color="navy" face="Verdana"><span style="font-size: 10pt; font-family: Verdana; color: navy;">But vtkShepard() accepts only 'dataset'
type in the method setInput()</span></font></p>
<p><font size="2" color="navy" face="Verdana"><span style="font-size: 10pt; font-family: Verdana; color: navy;"> </span></font></p>
<p><font size="2" color="navy" face="Verdana"><span style="font-size: 10pt; font-family: Verdana; color: navy;">Once, the input is defined, in what
format do you get the output?</span></font></p>

<p><font size="2" color="navy" face="Verdana"><span style="font-size: 10pt; font-family: Verdana; color: navy;">I am using VC++ 7.1 compiler on Win XP.</span></font></p>
