vtkStructuredPoints
A subclass of ImageData.
Definition: vtkStructuredPoints.h:35
vtkDataReader
helper superclass for objects that read vtk data files
Definition: vtkDataReader.h:54
vtkRectilinearGrid
a dataset that is topologically regular with variable spacing in the three coordinate directions
Definition: vtkRectilinearGrid.h:51
vtkDataReader::PrintSelf
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
vtkStructuredGrid
topologically regular array of data
Definition: vtkStructuredGrid.h:57
vtkSimpleReader::ReadMetaDataSimple
virtual int ReadMetaDataSimple(const std::string &, vtkInformation *)
A subclass can override this method to provide meta data specific to a particular file.
Definition: vtkSimpleReader.h:94
vtkReaderAlgorithm::CreateOutput
virtual vtkDataObject * CreateOutput(vtkDataObject *currentOutput)
This can be overridden by a subclass to create an output that is determined by the file being read.
Definition: vtkReaderAlgorithm.h:52
vtkDataSetReader
class to read any type of vtk dataset
Definition: vtkDataSetReader.h:47
vtkDataReader.h
vtkIndent
a simple class to control print indentation
Definition: vtkIndent.h:33
vtkDataReader::New
static vtkDataReader * New()
vtkDataSet
abstract class to specify dataset behavior
Definition: vtkDataSet.h:56
vtkInformation
Store vtkAlgorithm input/output information.
Definition: vtkInformation.h:64
vtkX3D::string
Definition: vtkX3D.h:496
vtkPolyData
concrete dataset represents vertices, lines, polygons, and triangle strips
Definition: vtkPolyData.h:84
vtkUnstructuredGrid
dataset represents arbitrary combinations of all possible cell types
Definition: vtkUnstructuredGrid.h:86
vtkDataReader::ReadMeshSimple
int ReadMeshSimple(const std::string &, vtkDataObject *) override
Overridden with default implementation of doing nothing so that subclasses only override what is need...
Definition: vtkDataReader.h:497
vtkDataObject
general representation of visualization data
Definition: vtkDataObject.h:58
vtkAlgorithm::FillOutputPortInformation
virtual int FillOutputPortInformation(int port, vtkInformation *info)
Fill the output port information objects for this algorithm.
