[vtkusers] VTK Stereo Rendering

[mailagentrus]

Hi! I want to add a stereo mode to my program. Program wil be show pairs of
images image in stereo mode (with Nvidia 3d vision). I set up NVidia Qudro
410 and saw stereo mode with Polydata object with using Paraview.
But, when I try to make own program i see inly the firs pair images in
stereo mode, after that image in right eye does not update... Updates inly
the left eye image.
Help me, please!

Code:

#include <vtkPolyDataReader.h>
#include <vtkSmartPointer.h>
#include <vtkDataSetMapper.h>
#include <vtkActor.h>
#include <vtkRenderWindow.h>
#include <vtkRenderer.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkCamera.h>
#include "vtkCommand.h"
#include "vtkImageData.h"
#include <vtkBMPReader.h>
#include <vtkImageViewer2.h>
#include <vtkImageActor.h>

vtkSmartPointer<vtkBMPReader> readerR;
vtkSmartPointer<vtkBMPReader> readerL;
vtkSmartPointer<vtkImageViewer2> imageViewer;

class vtkTimerCallback : public vtkCommand
{
  public:
    static vtkTimerCallback *New()
    {
      vtkTimerCallback *cb = new vtkTimerCallback;
      cb->TimerCount = 0;
      return cb;
    }
 
    virtual void Execute(vtkObject *vtkNotUsed(caller), unsigned long
eventId,
                         void *vtkNotUsed(callData))
    {
      if (vtkCommand::TimerEvent == eventId)
        {

// for example name for left eye image is
		readerL->SetFileName ( "D:/1234/-40.bmp");
		readerL->Update();

// for example name for right eye image is
		readerR->SetFileName ( "D:/1234/40.bmp");
		readerR->Update();
		
		imageViewer->SetInput(readerL->GetOutput());
		imageViewer->GetRenderWindow()->SetStereoTypeToLeft();
		imageViewer->GetRenderWindow()->Render();
  imageViewer->GetRenderer()->ResetCamera();
		imageViewer->GetRenderWindow()->Render();

		imageViewer->GetRenderWindow()->StereoUpdate();

		imageViewer->SetInput(readerL->GetOutput());
		imageViewer->GetRenderWindow()->SetStereoTypeToRight();
		imageViewer->GetRenderWindow()->Render();
  imageViewer->GetRenderer()->ResetCamera();
		imageViewer->GetRenderWindow()->Render();

		imageViewer->GetRenderWindow()->StereoUpdate();

        ++this->TimerCount;
        }
        cout << this->TimerCount << endl;
    }
 
  private:
    int TimerCount;

};


int main ( int argc, char *argv[] )
{
  //Read the image
   readerL =
    vtkSmartPointer<vtkBMPReader>::New();
  readerL->SetFileName ( "D:/1234/-5.bmp");
  readerL->Update();

   readerR =
    vtkSmartPointer<vtkBMPReader>::New();
  readerR->SetFileName ( "D:/1234/5.bmp");
  readerR->Update();

  // Visualize
  imageViewer =
    vtkSmartPointer<vtkImageViewer2>::New();

   vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
    vtkSmartPointer<vtkRenderWindowInteractor>::New();
  imageViewer->SetupInteractor(renderWindowInteractor);

    imageViewer->GetRenderWindow()->SetSize( 800, 600 );

  imageViewer->GetRenderWindow()->StereoCapableWindowOn();
  imageViewer->GetRenderWindow()->SetStereoTypeToCrystalEyes();
  imageViewer->GetRenderWindow()->SetStereoRender(1);
  imageViewer->GetRenderWindow()->StereoUpdate();

 renderWindowInteractor->Initialize();

  imageViewer->SetInput(readerBase->GetOutput());
  imageViewer->GetRenderWindow()->Render();
  imageViewer->GetRenderer()->ResetCamera();
		imageViewer->GetRenderWindow()->Render();

   // Sign up to receive TimerEvent
  vtkSmartPointer<vtkTimerCallback> cb = 
    vtkSmartPointer<vtkTimerCallback>::New();
  renderWindowInteractor->AddObserver(vtkCommand::TimerEvent, cb);

  int timerId = renderWindowInteractor->CreateRepeatingTimer(100);
  std::cout << "timerId: " << timerId << std::endl;  
  
  renderWindowInteractor->Start();

   return EXIT_SUCCESS;
}
