// .NAME vtkPolyDataReader - read vtk polygonal data file
|
||
|
|
// .SECTION Description
|
||
|
|
// vtkPolyDataReader is a source object that reads ASCII or binary
|
||
|
|
// polygonal data files in vtk format (see text for format details).
|
||
|
|
// The output of this reader is a single vtkPolyData data object.
|
||
|
|
// The superclass of this class, vtkDataReader, provides many methods for
|
||
|
|
// controlling the reading of the data file, see vtkDataReader for more
|
||
|
|
// information.
|
||
|
|
// .SECTION Caveats
|
||
|
|
// Binary files written on one system may not be readable on other systems.
