Hi, VTKers.<BR>
<BR>
I wanna visualize the zero value iso curve of a distance map overlaid on the map, ( the zero levelset curve ). The problem is I can only see the distance map. If I rotate or zoom, even a little bit, then I can clearly see the iso curve is actually there. Why can't I visualize it at the first place?<BR>
<BR>
I use vtkContourFilter to extract the iso curve, add it to the vtkPolyDataMapper, then VtkActor. <BR>
Distance map is added to vtkImageActor.<BR>
<BR>
Thanks<BR>
