[Kst] WG: Contribution NetCDF-interface: --> plotting of PACKED/COMPRESSED DATA and MATRIX COMPONENTS

[Rix, Patrick]

(attachement   'kst-src-datasources-netcdf_PRIX-2013-04.09.zip'   removed for mailing list)

Dear KST-developers,
dear Nicolas,

I finally succeeded in compiling KST and enhancing the NetCDF data interface by adding support for

  +++ plotting of PACKED DATA (using signed short integers as data type in combination with scaling attributes 'scale_factor' and 'add_offset') and
  +++ plotting COMPONENTS of a time dependent MATRIX,     X_[time, j_comp]  as vectors   x_j{time}

which I wanted to contribute to the KST-project (--> attached ZIP-archive) hoping that it will be useful to others, too and gets included into the main stream.
The only file that has been affected to changes was :     kst\src\datasources\netcdf\netcdfsource.cpp

I also added some comments there on the main idea and strategy of the implementation details which needed a little bit of cheating.
Thus it  would be good if someone else could have a look on the code, seeing how it could be implemented in a more elegant way - so:
any feedback will be warmly appreciated.

Componets of Matrices can be selected in the Data Wizard dialog being shown as vectors.
For example a matrix   X_vec3[time,1..3]   with the time dependend position vector representing the trajectory of a particle will appear in the field selection window as three vectors:    X_vec3.[01] ,  X_vec3.[02]  and  X_vec3.[03] .

If anyone wants to try the new interface version, I can send an archive (~45MB) with the Windows binary (compiled with Microsoft Visual Studio 10 Express) and all plugin-DLLs if you drop me a note.


Best Regards,
Patrick Rix.
