Summary0013249: Segfaults with dataset read from .csv
DescriptionGiven the attached csv file I get different segfaults. This is all with PV 3.14.1, happens in official binaries, as well as in a custom-compiled RelWithDebInfo build. Ubuntu Lucid, x86_64.

1st situation:
- Open csv file, apply default reader settings, data in table looks good
- Add a Table to Points filter, X column=x, etc
- Interestingly, the data at this point consists of a single cell with 25000 points
- Add a calculator filter, name result array 'v', expression 'vx*iHat+vy*jHat+vz*kHat'
- Newly added vector data looks good in table view
- Add a Mask points filter to the calculator output, #points=200, random sampling
- Add Streamtracer with custom source, input=calculator, source=maskpoints, apply
- SEGFAULT

2nd situation (similar, but using Python calculator):
- Open csv file, apply default reader settings, data in table looks good
- Add a Table to Points filter, X column=x, etc
- Add a Python calculator filter, name result array 'v', expression 'hstack([vx,vy,vz])'
- Newly added vector data looks good in table view
- Add a Mask points filter to the calculator output, #points=200, random sampling
- Add Streamtracer with custom source, input=calculator, source=maskpoints, apply
- SEGFAULT

 According to http://www.paraview.org/Wiki/Display_points_and_normals_from_a_plain_text_%28x_y_z_nx_ny_nz%29_file [^] at least the part about combining 3 scalars to vectors with Calculators should be legal ;-)

 I think what's "illegal" is trying to trace a streamline in a dataset comprising of just points. There are no cells in the dataset. You need to write a special reader that reads your raw data as an vtkImageData or a vtkStructuredGrid or something of that sort and then the stream tracer would work.

 I admit that there's only a single cell in the TableToPoints and Calculator outputs. But it's the Mask points filter that creates a set with 0 cells. Enabling "Generate vertices" the mask points filter leads to a set with 1 cells. On this the stream tracer also segfaults.

 What Utkarsh mean by "dataset comprising of just points", is that is not composed of 3D cell but only 1D cell. And the stream tracer can only work in a volume of 3D cells.
