<p style="margin: 0cm 0cm 0.0001pt;"><span lang="EN-US" style="font-family: Calibri, sans-serif;">I am really new in vtk programming, so there may be a lot of things I donīt know yet or that I did wrong, please let me know if there is a simpler way to do what
I am doing.<o:p></o:p></span></p>

<p style="margin: 0cm 0cm 0.0001pt;"><span lang="EN-US" style="font-family: Calibri, sans-serif;">Right now I have the following problem and I hope you will be able to give me the solution or point me in the right direction.<o:p></o:p></span></p>
<p style="margin: 0cm 0cm 0.0001pt;"><span lang="EN-US" style="font-family: Calibri, sans-serif;">I am using XMLStructuredGrid files (.vts) so I am opening them with the vtkXMLStructuredGridReader(). Then I am using a<span class="apple-converted-space"> </span>vtkStructuredGridGeometryFilter()
and making a Deepcopy of it with a vtkPolyData() so that I can add the scalars extracted from the Reader. As Mapper I am using a vtkOpenGLPolyDataMapper() and vtkLODActor() as an actor.<o:p></o:p></span></p>

<p style="margin: 0cm 0cm 0.0001pt;"><font face="Calibri, sans-serif">Using this piece of code:</font></p>
<p style="margin: 0cm 0cm 0.0001pt;"><span lang="EN-US" style="font-family: Calibri, sans-serif;"><o:p> </o:p></span></p>

<p style="margin: 0cm 0cm 0.0001pt;"><span lang="EN-US" style="font-family: Calibri, sans-serif;">gridreader.SetFilename(filename)<o:p></o:p></span></p>

</span></p>
<p style="margin: 0cm 0cm 0.0001pt;"><font face="Calibri, sans-serif">I get the following dimensions <span style="font-family: Calibri, sans-serif; font-size: 16px;">(384, 216, 257)</span></font></p>

</span></font></p>
<p style="margin: 0cm 0cm 0.0001pt;"><span lang="EN-US" style="font-family: Calibri, sans-serif;">The thing is that the Bounds that I get using: "gridreader = gridreader.GetOutput().GetBounds()" are<span class="apple-converted-space"> </span>(0.0, 215.0, 0.0,
383.0, 0.0, 240.0). <o:p></o:p></span></p>
<p style="margin: 0cm 0cm 0.0001pt;"><span lang="EN-US" style="font-family: Calibri, sans-serif;">So... My problem is that when I render my Data, I can't se <span style="font-family: Calibri, sans-serif; font-size: 16px;">the whole Data extension.</span></span></p>
<p style="margin: 0cm 0cm 0.0001pt;"><span lang="EN-US" style="font-family: Calibri, sans-serif;">I am also using vtkImplicitPlaneWidget() (that the user can move) to catch the position that the user selected moving the plane with the mouse, but I canīt move
the plane through the whole extension of the X axis because the bounds are smaller than the size of my Data. <o:p></o:p></span></p>
<p style="margin: 0cm 0cm 0.0001pt;"><span lang="EN-US" style="font-family: Calibri, sans-serif;"><br>
</span></p>
<p style="margin: 0cm 0cm 0.0001pt;"><span lang="EN-US" style="font-family: Calibri, sans-serif;">I have tryed to modify the bounds several times, but i haven't been able to render the whole data extension.</span></p>
<p style="margin: 0cm 0cm 0.0001pt;"><span lang="EN-US" style="font-family: Calibri, sans-serif;"><br>
</span></p>
<p style="margin: 0cm 0cm 0.0001pt;"><span lang="EN-US" style="font-family: Calibri, sans-serif;">Maybe I am wrong and the bounds aren't my problem, but I would be very
