Re: [Paraview] Sum values of scalar vector
Hi,
in a programmable Filter do something like this:
import math
input = self.GetInputDataObject(0, 0)
output = self.GetOutputDataObject(0)
COUNT=input.GetNumberOfPoints()
pd=input.GetPointData()
m=0
v=0
for i in xrange(COUNT):
r=pd.GetArray('radius').GetValue(i)
v=v+((4.0/3.0)*math.pi*r*r*r)
m=m+pd.GetArray('Mass').GetValue(i)
outputarray = vtk.vtkStringArray()
outputarray.SetName(Text)
outputarray.SetNumberOfTuples(1)
outputarray.SetValue(0,N=%d\nV=%1.6f m³\nm=%1.6f kg % (COUNT,v,m))
output.GetRowData().AddArray(outputarray)
Attention: if you save this to a state-file change the ³ to 3 because it
will not be escaped and you can not load the state anymore.
best wishes,
Christian

want to use. Any tips will be appreciated.

[Paraview] how to select data for Plot Variables over Time?
Hello, I'm trying to calculate volumes that I'm generating, how they change over time. To get the volume, I do Polydata - Gaussian Resampling - IsoVolume - Integrate Variables, Cell Data, and the results are pretty good. I want to get this data for every timestep, e.g. in a table that I can export and analyze externally. I tried applying Plot Global Variables Over Time when Integrate Variables is selected, but the resulting dataset has 0 for vtkValidPointMask at every timestep. I tried selecting Integrate Variables in these ways: - Integrate Variables filter in the pipeline browser - In Spreadsheet View, going to Integrate Variables - Cell Data and clicking on the row with the volume info (which is the only row) - In 3D view, visualizing integrate variables (it's a point) and doing Select Points On or Select Points through, per this post: http://www.mail-archive.com/paraview@paraview.org/msg05757.html (where it apparently worked) Any advice?

Re: [Paraview] ParaView thinks that it does not have a wind blade reader
At this point the changes will have to wait, unfortunately. For the past two weeks I've been involved with a TopoInVis submission so I couldn't get around to it. I'll look at it this weekend.

Re: [Paraview] Problem building from source
Still more problems building... I have python wrapping turned on, and it built fine. But I tried to run a programmable filter that uses vtk.vtkExtractGrid() and it says it doesn't exist in the module. So I looked through the CMakeCache.txt and Module_vtkFiltersGeneral and Module_vtkFiltersExtraction were both set to INTERNAL and OFF. I couldn't figure out how to make them appear, so on a whim I changed them both to ON and reconfigured and regenerated. This made them appear in the ccmake screen. Then I built and no errors. However, vtkExtractGrid() is still not inside the python module vtk. But, in the install tree I have: grep vtkExtractGrid * -R Binary file lib/paraview-3.14/vtkFiltersExtractionPython.so matches Binary file lib/paraview-3.14/libvtkFiltersParallelImaging-pv3.14.so.1 matches Binary file lib/paraview-3.14/libvtkFiltersExtraction-pv3.14.so matches Binary file lib/paraview-3.14/libvtkFiltersParallelImaging-pv3.14.so matches Binary file lib/paraview-3.14/libvtkFiltersExtractionPython27D-pv3.14.so matches Binary file lib/paraview-3.14/libvtkFiltersExtraction-pv3.14.so.1 matches Binary file lib/paraview-3.14/libvtkFiltersParallel-pv3.14.so matches Binary file lib/paraview-3.14/libvtkFiltersGeometryPython27D-pv3.14.so.1 matches Binary file lib/paraview-3.14/libvtkPVVTKExtensionsDefaultPython27D-pv3.14.so.1 matches Binary file lib/paraview-3.14/libvtkPVVTKExtensionsDefault-pv3.14.so.1 matches Binary file lib/paraview-3.14/libvtkFiltersGeometryPython27D-pv3.14.so matches Binary file lib/paraview-3.14/libvtkPVVTKExtensionsDefault-pv3.14.so matches Binary file lib/paraview-3.14/libvtkFiltersExtractionCS-pv3.14.so matches Binary file lib/paraview-3.14/libvtkImagingCorePython27D-pv3.14.so.1 matches Binary file lib/paraview-3.14/libvtkImagingCorePython27D-pv3.14.so matches Binary file lib/paraview-3.14/libvtkFiltersExtractionPython27D-pv3.14.so.1 matches Binary file lib/paraview-3.14/libvtkPVVTKExtensionsDefaultPython27D-pv3.14.so matches Binary file lib/paraview-3.14/libvtkFiltersExtractionCS-pv3.14.so.1 matches Binary file lib/paraview-3.14/libvtkFiltersParallel-pv3.14.so.1 matches So I don't know why I don't have access to it from pvpython.
