Hi, <br>
<br>
I wanted to know how I can get cell or array information form vtk. I'm using vtkContourFilter on some data that I have read, <br>
<br>
NOW I ONLY WANT TO GET THE COORDINATES of the POLYGONS on the CONTOUR..<br>
<br>
how can I do this?? <br>
<br>
I've tried GetNextCell() but it returns zero? <br>
I've read the class referrence and tried all the funcions but for some
reason the data is read properly and rendered but when I try to extract
the PolyData, I get nothing, <br>
ie <br>
<br>
for lets say after reading the data, I try getCells() functions I get a nice round 0. <br>
<br>
I know it's reading properly because it renders fine....<br>
<br>
Q: <br>
<br>
How can I get the coordinates out of the polydata once i've applied the contourfilter??<br>
<br>
<br>
Thankyou,<br>
<br>
