[Paraview] xyzc file to vtk

[Paulo Herrera]

Hi Luca,

There are many ways to do this. However, if you are familar with
python I would suggest you take a look at PyEVTK:
https://bitbucket.org/pauloh/pyevtk/overview.

If you want to use PyEVTK, you'll have to:

1) Read your data and store it in 4 numpy arrays: x, y, z and C.
2) Write the following two lines to export them as a VTK file:
       from evtk.hl import pointsToVTK
       pointsToVTK("./points", x, y, z, data = {"C" : C })

This will create a point.vtu file in the current directory which
contains an unstructured VTK grid.
If the coordinates x, y, z are the vertices of a rectilinear or
structured grid, you could also export the data as a structured or
rectilinear grid (see the VTK file format document for details). There
are examples in PyEVTK of how to do this.

Good luck,

Paulo
