<p class="MsoPlainText">So I turned SliceFacesCamera Off and it SetSlicePlane with a vtkPlane object. Now, though the corresponding slice has been extracted, there are two issues that I face, that I would appreciate your advice on, immensely.<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hi Debjit, <br>
<br>
You probably have SliceFacesCamera turned on for the mapper. This <br>
will override any plane that you set manually. <br>
<br>
If you are using SliceFacesCamera and SliceAtFocalPoint, then the way <br>
to change the slice is by changing the camera's position and focal <br>
point. <br>
