* @class vtkEnSight6Reader
|
|
* @brief class to read EnSight6 files
|
|
*
|
|
* vtkEnSight6Reader is a class to read EnSight6 files into vtk.
|
|
* Because the different parts of the EnSight data can be of various data
|
|
* types, this reader produces multiple outputs, one per part in the input
|
|
* file.
|
|
* All variable information is being stored in field data. The descriptions
|
|
* listed in the case file are used as the array names in the field data.
|
|
* For complex vector variables, the description is appended with _r (for the
|
|
* array of real values) and _i (for the array if imaginary values). Complex
|
|
* scalar variables are stored as a single array with 2 components, real and
|
|
* imaginary, listed in that order.
|
|
* @warning
|
|
* You must manually call Update on this reader and then connect the rest
|
|
* of the pipeline because (due to the nature of the file format) it is
|
|
* not possible to know ahead of time how many outputs you will have or
|
|
* what types they will be.
|
|
* This reader can only handle static EnSight datasets (both static geometry
|
|
* and variables).
