[Paraview] Connecting glyph filter with data
Hi, I have a plugin which I'm trying to get working in ParaView 3.98. The source code for the plugin can be found here: http://github.com/mantidproject/mantid/blob/6315_build_pv_398/Code/Mantid/Vates/ParaviewPlugins/ParaViewReaders/PeaksReader/vtkPeaksReader.cxx. https://github.com/mantidproject/mantid/blob/6315_build_pv_398/Code/Mantid/Vates/ParaviewPlugins/ParaViewReaders/PeaksReader/vtkPeaksReader.cxx After fixing function calls on the vtkPVGlyphFilter to get it to compile (lines 96 and 97), the plugin crashes at the vtkGlyphFilter::Update() call on vtkPoints::GetNumberOfPoints(). I checked the structuredMesh (it's actually a vtkUnstructuredGrid) object used in the vtkGlyphFilter::SetInputData() call and found that it does contain data points (40 for the particular file I'm looking at). I did some digging about the vtkGlyphFilter::SetInputData() and found that it no longer sets up a pipeline connection. I think this might be the cause of the glyph filter not finding any data, but I'm unsure. However, I'm having trouble figuring out how to use vtkGlyphFilter::SetInputConnection() and the structuredMesh object. Is there anyway to make this work using the structuredMesh object or is the best thing to make another plugin to create the structuredMesh and then do vtkGlyphFilter::SetInputConnection(newPlugin-GetOutputPort()) and remove the vtkGlyphFilter::SetInputData() call?

Re: [Paraview] Connecting glyph filter with data
Michael, In vtkPeaksReader::RequestData, instead of glyphFilter-SetSourceData(sphere-GetOutput()), do EITHER glyphFilter-SetSourceConnection(sphere-GetOutputPort()) OR sphere-Update() glyphFilter-SetSourceData(sphere-GetOutput()) Unlike the old SetInput()/SetSource() methods, SetInputData()/SetSourceData() don't set the pipeline connections between the produces and consumers. So when you called SetSourceData(sphere-GetOutput()), the current state of the output of vtkSphereSource was passed on to the glyph filter. Since the SphereSource hadn't executed yet, it was empty. So we can fix the problem by either setting up a true pipeline connection (using SetSourceConnection) or by ensuring that the SphereSource has produced valid data by calling sphere-Update() Utkarsh On Wed, Jan 2, 2013 at 10:50 AM, Michael Reuter reute...@ornl.gov wrote: Hi, I have a plugin which I'm trying to get working in ParaView 3.98.

Hi Utkarsh, I love one line changes. Works like a charm.
