PolyDataAlgorithmReader

VTKExamples/Cxx/Developers/PolyDataAlgorithmReader

Description

This example demonstrates a reader that takes nothing as input and produces a vtkPolyData as output.

Code

PolyDataAlgorithmReader.cxx

#include <vtkSmartPointer.h>
#include <vtkPolyData.h>

#include "vtkTestReader.h"

int main (int, char *[])
{
  vtkSmartPointer<vtkTestReader> reader =
    vtkSmartPointer<vtkTestReader>::New();
  reader->Update();

  vtkPolyData* polydata = reader->GetOutput();
  polydata->Print(std::cout);

  return EXIT_SUCCESS;
}
