Can you explain me how can I apply the gradient filter using python
this is my code from paraview import servermanager from paraview.simple import* connection = servermanager.Connect() reader.FileName ="/Users/........../disk_out_ ref.ex2" reader.UpdatePipeline() pointData = servermanager.filters.CellDataToPointData(Input=reader) pointData.UpdatePipeline() gradData = servermanager.filters.CellDataToPointData(Input=reader) servermanager.filters.Contour.ContourBy = True servermanager.filters.Contour.Isosurfaces = True contourData = servermanager.filters.Contour(Input=pointData) contourData.ContourBy = 'Temp' contourData.Isosurfaces = [400] contourData.UpdatePipeline() servermanager.filters.DecimatePro.TargetReduction = True dec = servermanager.filters.DecimatePro(Input=contourData) dec.TargetReduction = 0.9 dec.UpdatePipeline() view = servermanager.CreateRenderView() Show(dec, view) Render(view) Thanks On Fri, Apr 27, 2012 at 6:01 PM, David E DeMarle <dave.dema...@kitware.com>wrote: > Apply the gradient filter first to make the temp gradient field, then > contour the output of that but choose the original temp field as the > one to contour.
