[vtkusers] How to read and visualize ".ply" file in VTK using C++ 2008

[S. Akter]

Hello Everybody

 

I'm new to VTK and I'm working on a project that needs to read “.ply”
files. I test the following example taken from website that read “.ply” file in
visual c++ 2008 express edition. The program build and debug successfully but visualize
nothing. What are the wrong? I could not understand.

 

The following are the program code:



 



 

#include <vtkPolyData.h>

#include <vtkPLYReader.h>

#include <vtkSmartPointer.h>

#include <vtkPolyDataMapper.h>

#include <vtkActor.h>

#include <vtkRenderWindow.h>

#include <vtkRenderer.h>

#include <vtkRenderWindowInteractor.h>

 

int main ( int argc, char *argv[]
)

{

// Verify input arguments

 

  if(argc != 2)

    {

    std::cout << "Usage: " << argv[0] << "trucks.ply" << std::endl;

    return EXIT_FAILURE;

    }

 

  std::string
inputFilename = argv[1];

 

 
vtkSmartPointer<vtkPLYReader> reader =

   
vtkSmartPointer<vtkPLYReader>::New();

 
reader->SetFileName ( inputFilename.c_str() );

 

  // Visualize

 
vtkSmartPointer<vtkPolyDataMapper> mapper =

   
vtkSmartPointer<vtkPolyDataMapper>::New();

 
mapper->SetInputConnection(reader->GetOutputPort());

 

 
vtkSmartPointer<vtkActor> actor =

   
vtkSmartPointer<vtkActor>::New();

 
actor->SetMapper(mapper);

 

 
vtkSmartPointer<vtkRenderer> renderer =

   
vtkSmartPointer<vtkRenderer>::New();

 
vtkSmartPointer<vtkRenderWindow> renderWindow =

    vtkSmartPointer<vtkRenderWindow>::New();

 
renderWindow->AddRenderer(renderer);

 
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor
=

   
vtkSmartPointer<vtkRenderWindowInteractor>::New();

 
renderWindowInteractor->SetRenderWindow(renderWindow);

 

  renderer->AddActor(actor);

 
renderer->SetBackground(0.1804,0.5451,0.3412); // Sea green

 

 
renderWindow->Render();

 
renderWindowInteractor->Start();

 

  return EXIT_SUCCESS;

}



 



  

After build I get the following output:



 



 

1>------ Build started: Project: ReadPLY, Configuration:
Debug Win32 ------

1>Compiling...

1>ReadPLY.cpp

1>Linking...

1>Embedding manifest...

2>Project not selected to build for this solution
configuration 

========== Build: 1 succeeded, 0 failed, 1 up-to-date, 1
skipped ==========

 



 



 

After debugging I get the following output, but don’t
visualize anything

Thank you in
advance for any help or suggestions.
