I had some figuring this one out. Here is the pipeline: reader -> contour -> triangle strips -> (extract selection) -> clean to grid -> extract surface
The purpose of each filter is: contour: extract the boundary triangle strips: combine the points of each line to create polylines. Otherwise, each line segment is a separate cell. extract selection: extract one of the polylines if there are more than one (optional) clean to grid: convert to unstructured grid and remove duplicate points extract surface: convert to polydata. This filter has the useful side effect of ordering points along the polyline so that the polyline has points 0, 1, 2, 3... instead of 0, 5, 3, 9. This is necessary for plotting Once you apply this pipeline, you can create a XY Plot view and plot any variable along the curve. I can't remember if this worked on 3.4. It definitely works with the development (cvs) version of ParaView. In the next version, there will probably be one filter that does everything I described here. -berk On Fri, Dec 5, 2008 at 5:26 PM, Berk Geveci <[email protected]> wrote: > I am guessing this is a 2D contour, correct?
