I need to initialize multiple contours over the multiple segmented regions by vtkcontourwidget for editing. It is easy if there is only one contour to initialize in one slice. But it is a different story if there are multiple contours to initialize in one slice. Does anyone have any good ideas?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal>Yang<o:p></o:p></p></div></body></html>
