// .NAME vtkEnSightGoldBinaryReader - class to read binary EnSight Gold files
|
|
// .SECTION Description
|
|
// vtkEnSightGoldBinaryReader is a class to read EnSight Gold 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.
|
|
// .SECTION Caveats
|
|
// 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).
|
|
// .SECTION Thanks
|
|
// Thanks to Yvan Fournier for providing the code to support nfaced elements.
