<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif">
<DIV>Well the problem is that I'm using a region growing method to find the regions. So the pixels in each region won't be having predictable values. I guess I need to know the values if I want to draw a contour, using vtkContourFilter. I guess vtkExtractEdges or vtkEdgePoints might be useful, but I'm not successful with getting them to work yet. I was hoping someone might come up with an idea :-/</DIV>

<DIV dir=ltr>Hi, Shaadi<BR><BR>as you have mentioned contouring.....You can get the points from the data output of a vtkContourFilter (provided you have contoured it well enough to get the boundary dataset). <BR><BR>Regards<BR>Brian<BR><BR>

<DIV>Can someone please tell me how I can find the boundary points of a selection of points. I have regions consisting of pixels or points and I want to draw a contour around them. I'm thinking of finding the border points and later on attaching them. </DIV>
