<div>Hi,</div>
<div>Here is what I want to do (I believe these are very basic): </div>
<div> </div>
<div>1. load and view a 3D dataset. </div>
<div>2. scroll to view each slice</div>
<div>3. draw contours on multiple slices.</div>
<div>4. create a suface using these contours. </div>
<div> </div>
<div>I have been able to load the data and view it with vtkImageViewer2 and scroll though the slices. </div>
<div> </div>
<div>I used vtkContourWidget to draw contour. Problems that I am facing are as follows:</div>
<div> </div>
<div>1. The contour does not stick to the slice. When I scroll to a different slice it stays on the screen only the . </div>
<div> </div>
<div> I want the contour to pertain to the particular slice. Is there a way to achieve this?</div>
<div> </div>
<div>(I somehow hacked the behavior by Disabling the ContourWidget when the slice is changed)</div>
<div> </div>
<div>2. The other major concern at this point is whether I can draw multiple contours using vtkcontourWidget. Please advice how this can I achieve this. </div>
<div> </div>
<div>Thank you in advance,</div>
<div>PDB</div>
