* @brief read NetCDF files
|

|
|
*
|
|
* vtkNetCDFPOPReader is a source object that reads NetCDF files.
|
|
* It should be able to read most any NetCDF file that wants to output a
|
|
* rectilinear grid. The ordering of the variables is changed such that
|
|
* the NetCDF x, y, z directions correspond to the vtkRectilinearGrid
|
|
* z, y, x directions, respectively. The striding is done with
|
|
* respect to the vtkRectilinearGrid ordering. Additionally, the
|
|
* z coordinates of the vtkRectilinearGrid are negated so that the
|
|
* first slice/plane has the highest z-value and the last slice/plane
|
|
* has the lowest z-value.
