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;
}
