Detailed Description

class to read binary EnSight Gold files

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.

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).

Thanks:: Thanks to Yvan Fournier for providing the code to support nfaced elements.

Member Function Documentation

static vtkEnSightGoldBinaryReader* vtkEnSightGoldBinaryReader::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkGenericEnSightReader.

virtual const char* vtkEnSightGoldBinaryReader::GetClassName ( ) [virtual]

Reimplemented from vtkEnSightReader.

static int vtkEnSightGoldBinaryReader::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkEnSightReader.

virtual int vtkEnSightGoldBinaryReader::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkEnSightReader.

Reimplemented from vtkEnSightReader.

virtual void vtkEnSightGoldBinaryReader::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
