[vtkusers] display .vtk files in window

[vikrant manne]

Hi Gurujan,
You can try implementing the following cpp code to java. I guess this works
for VtkPolyData files.
Try using different Data readers (PolyDataReader, UnstructuredGridReader or
DataSetReader) depending on your VTK file.



// necessary headers from VTK Library
#include "vtkPolyDataMapper.h"
#include "vtkActor.h"
#include "vtkProperty.h"
#include "vtkRenderWindow.h"
#include "vtkRenderer.h"
#include "vtkRenderWindowInteractor.h"
#include <vtkDataSetWriter.h>
#include <vtkSphereSource.h>
#include <vtkPolyDataMapper.h>
#include <vtkDataSetMapper.h>
#include <vtkActor.h>
#include <vtkProperty.h>
#include <vtkPolyData.h>
#include <vtkDataSetReader.h>
#include <vtkDataSet.h>
#include <vtkPolyDataNormals.h>
#include <vtkTriangleFilter.h>
#include <vtkStripper.h>
#include <vtkPointData.h>
#include <vtkPolyDataWriter.h>
#include "vtkPolyDataReader.h"

#include <string>

// MAIN

int main ()
{
    std::string strCurFile = "VtkFile.vtk";
    // Initialising a reader to read the VTK files
    vtkPolyDataReader * pGridReader = vtkPolyDataReader::New();
    pGridReader->SetFileName (strCurFile.c_str());
    pGridReader->Update();

    vtkPolyData* pData=vtkPolyData::New();
    pData->DeepCopy(pGridReader->GetOutput());

    // Mapper to map polygonal data to graphics primitives
    vtkPolyDataMapper *Tmap = vtkPolyDataMapper::New();
    Tmap->SetInput(pData);
// Updating the polydatamapper
    Tmap->Update();
    // Actor - used to display all the geometry
    vtkActor* Actor = vtkActor::New();
    Actor->SetMapper(Tmap);
    Actor->VisibilityOn();

    // a renderer and render window
  vtkRenderer *ren1 = vtkRenderer::New();
      vtkRenderWindow *renWin = vtkRenderWindow::New();
      renWin->AddRenderer(ren1);

      // a window interactor
      vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
      iren->SetRenderWindow(renWin);

    // add the actors to the scene
      ren1->AddActor(Actor);

    //  ren1->AddActor(outlineActor);
      ren1->SetBackground(0.5,0.5,0.5); // Background color white

      // render an image (lights and cameras are created automatically)
      renWin->Render();

      // begin mouse interaction
      iren->Start();
    // Deleting all instances after rendering
    pGridReader->Delete();
    Tmap->Delete();
    pData->Delete();
    Actor->Delete();


}

Thanks,
Vikrant Manne
