[vtkusers] Creating a Volume from 2D BMP files.

[Sharwari Mavalankar]

hi all,
I am trying to create a 3D volume out of 2D Bmp slices.
I believe that the BMP files are being read because the outputis a 2D image
which I cannot render.
The output does not look like a volume but just a 2D image.
Here is my code.


#include "vtkRenderer.h"
#include "vtkRenderWindow.h"
#include "vtkRenderWindowInteractor.h"
#include "vtkBMPReader.h"
#include "vtkPolyDataMapper.h"
#include "vtkActor.h"
#include "vtkActor2D.h"
#include "vtkImageActor.h"
#include "vtkOutlineFilter.h"
#include "vtkCamera.h"
#include "vtkProperty.h"
#include "vtkPolyDataNormals.h"
#include "vtkContourFilter.h"
#include "vtkDataSetMapper.h"
#include "vtkImageMapper.h"


void main (void)
{

 vtkRenderer *aRenderer = vtkRenderer::New();
    vtkRenderWindow *renWin = vtkRenderWindow::New();

 renWin->AddRenderer(aRenderer);
    vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
    iren->SetRenderWindow(renWin);


 //create an instance of the class vtkBMPReader
 vtkBMPReader *br = vtkBMPReader::New();

 br->SetFilePrefix("C:\\Images\\conductivities\\slice");


 br->SetFilePattern("%s%d.bmp");


 br->SetFileNameSliceOffset(1);
 br->SetFileNameSliceSpacing(1);
 br->SetDataSpacing(1,1,0.1);
 br->SetDataOrigin(0,0,0);
 br->Update();


 vtkActor2D *Actor2D=vtkActor2D::New();
 vtkImageMapper *ImageMapper = vtkImageMapper::New();

 ImageMapper->SetInput(br->GetOutput());
 Actor2D->SetMapper(ImageMapper);


 aRenderer->AddActor(Actor2D);
 aRenderer->SetBackground(1,1,1);
 iren->Initialize();
    iren->Start();




}

Hope to get some help here!

Thanks

Sharwari
