<p class=MsoNormal>i m not still clear with what i want....<br>
<br>
Actually i have some vtk structured point data sets, and i am trying to
generate the isosurface in which i m using contour filter. <br>
in that i m setting the value of a single contour. My question is how to decide
what would be the value of this variable acc to data set?<br>
Like for one vtk file i found it works when it is 60,,,for second one it works
for 92.....<br>
So how to decide using the program (the source code) the value ?<o:p></o:p></p>

You’re probably over thinking it. No worries! It’s not very clear
in the docs.<br>
So for instance, lets say you want to generate 1 contour with a value of 100.<br>
The call would look like this:<br>
contour->SetValue(0, 100);<br>
<br>
If you wanted to change the value of this contour to 200 your call would be
like this:<br>
contour->SetValue(0, 200);<br>
<br>
Now if you wanted to generate another contour at 50 and keep the contour at 200
(thus totaling 2 contours) , after making the previous call you would add this:<br>
<br>
contour->SetValue(1,50);<br>
<br>
So in summary, if you just want one contour the contour number is always 0. If
you want more than one value the contour number is assigned by you and is <=
total number of contours.<br>

In that method:<br>
int “i” ==> the contour number <br>
double v ==> value of contour number “i”<br>
<br>
This is so that you can supply more than one contour value to the contour
filter.<br>

<br>
the class vtkContourFilter.h contains a method called<br>
<br>
SetValue(int i, double v);<br>
<br>
Anyone please tell me how to decide the value of v while using this filter.....<br>
