// .NAME vtkPChacoReader - Read Chaco files
|
|
// .SECTION Description
|
|
// vtkPChacoReader is a unstructured grid source object that reads
|
|
// Chaco files. The file is read by process 0 and converted into
|
|
// a vtkUnstructuredGrid. The vtkDistributedDataFilter is invoked
|
|
// to divide the grid among the processes.
