Re: [Paraview] VTK Data File Scalars Analysis

2015-10-19 Thread Cory Quammen 
VTK and ParaView have many reader classes. Did you have a particular format
in mind?If not, then I suggest to navigate to VTK/IO/ and look at the
source code contained therein.

HTH,
Cory

Thanks, now it's clear.

 Hi,

 I'd like to know how Paraview analyses scalar data from a VTK data
 file. Specially, how it extracts the components of a scalar and assigns
 names for color plots. For example if numComp is 3 they are named
 "Magnitude, X, Y and Z2, but if numComp is 6 they are named "Magnitude, XX,
 YY; ZZ, XY, XZ and YZ". How is this determined?

 Some questions I'd like to answer are: can this be done with only the
 VTK library? If not, are there any other library that can do it (e.g.
 paraview python)?

 Pointing to the specific code file in the git repository should be
 enough, but an explanation would be great!

 Thanks in advance and greetings.

Guillermo,

vtkSplitColumnComponents assigns the names based on a guess that
3-component arrays are vectors with X, Y, Z components and 6-component
arrays represent symmetric 3x3 matrices, i.e.

XX XY XZ
XY YY YZ
XZ YZ ZZ

See ParaView/ParaViewCore/VTKExtensions/Core/vtkPVPostFilter.cxx, lines

[Paraview] VTK Data File Scalars Analysis

2015-10-16 Thread Guillermo Giraldo 
Hi,

I'd like to know how Paraview analyses scalar data from a VTK data file.
Specially, how it extracts the components of a scalar and assigns names for
color plots. For example if numComp is 3 they are named "Magnitude, X, Y
and Z2, but if numComp is 6 they are named "Magnitude, XX, YY; ZZ, XY, XZ
and YZ". How is this determined?

Some questions I'd like to answer are: can this be done with only the VTK
library? If not, are there any other library that can do it (e.g. paraview
python)?

Pointing to the specific code file in the git repository should be enough,
but an explanation would be great!

Thanks in advance and greetings.
