In this example, we add 10 points to a polygonal data (polydata) object and write the result to a VTP file.

WriteVTP.cxx

#include <vtkVersion.h>
#include <vtkCellArray.h>
#include <vtkPoints.h>
#include <vtkXMLPolyDataWriter.h>
#include <vtkPolyData.h>
#include <vtkSmartPointer.h>
 
int main ( int, char *[] )
{
  // Create 10 points.
  vtkSmartPointer<vtkPoints> points = 
    vtkSmartPointer<vtkPoints>::New();
 
  for ( unsigned int i = 0; i < 10; ++i )
    {
    points->InsertNextPoint ( i, i, i );
    }
 
  // Create a polydata object and add the points to it.
  vtkSmartPointer<vtkPolyData> polydata = 
    vtkSmartPointer<vtkPolyData>::New();
  polydata->SetPoints(points);
 
  // Write the file
  vtkSmartPointer<vtkXMLPolyDataWriter> writer =  
    vtkSmartPointer<vtkXMLPolyDataWriter>::New();
  writer->SetFileName("test.vtp");
#if VTK_MAJOR_VERSION <= 5
  writer->SetInput(polydata);
#else
  writer->SetInputData(polydata);
#endif
 
  // Optional - set the mode. The default is binary.
  //writer->SetDataModeToBinary();
  //writer->SetDataModeToAscii();
 
  writer->Write();
 
  return EXIT_SUCCESS;
}
