[vtkusers] problem with vtkVolumeReader!!!!!

[Pingkun]

Hi,

Your code

--------------------------------------------------------------------------------------------------------------
vtkVolumeReader *vol = vtkVolumeReader::New();   
        v16->SetDataDimensions(64,64);                                 
        v16->SetImageRange (1,217) 
        v16->SetDataByteOrderToLittleEndian();
        v16->SetFilePrefix("brain");
        v16->SetDataSpacing (3.5,3.5,1.2);
        v16->Update();
-------------------------------------------------------------------------

looks strange. Why do you use "v16" but declare "*vol" instead? Isn't it a compile error?

  hello 

  I am working in an application that reads volumenes thus I want to occupy to vtkVolumeReader to read them but when initializing I have a problem with vtkVolumeReader.

  I have a problem with vtkVolumeReader, to I want to read a volume with it but when inicilizar it it says to me that a conversion of * vtkObject cannot be made in * vtkVolumeReader.

  help me.

  #include "vtkPolyDataMapper.h"
  #include "vtkActor.h"
  #include "vtkRenderer.h"
  #include "vtkRenderWindow.h"
  #include "vtkRenderWindowInteractor.h"
  #include "vtkProperty.h"
  #include "vtkCamera.h"
  #include "vtkContourFilter.h"
  #include "vtkVolumeReader.h"
  #include "vtkPolyDataNormals.h"

  int main (int argc, char **argv)
  {

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

  vtkVolumeReader *vol = vtkVolumeReader::New();   
          v16->SetDataDimensions(64,64);                                 
          v16->SetImageRange (1,217) 
          v16->SetDataByteOrderToLittleEndian();
          v16->SetFilePrefix("brain");
          v16->SetDataSpacing (3.5,3.5,1.2);
          v16->Update();

   vtkContourFilter *skinExtractors = vtkContourFilter::New();
      skinExtractors->SetInput((vtkDataSet *) v16->GetOutput());
      skinExtractors->SetValue(0, 500);
    vtkPolyDataNormals *skinNormals = vtkPolyDataNormals::New();
      skinNormals->SetInput(skinExtractors->GetOutput());
      skinNormals->SetFeatureAngle(60.0);
    vtkPolyDataMapper *skinMapper = vtkPolyDataMapper::New();
      skinMapper->SetInput(skinNormals->GetOutput());
      skinMapper->ScalarVisibilityOff();
    vtkActor *skin = vtkActor::New();
      skin->SetMapper(skinMapper);

    aRenderer->AddActor(skin);
    aRenderer->SetActiveCamera(aCamera);
    aRenderer->ResetCamera ();
    aCamera->Dolly(1.5); 


    aRenderer->SetBackground(1,1,1);
    renWin->SetSize(640, 480);


    aRenderer->ResetCameraClippingRange ();

    iren->Initialize();
    iren->Start();


    v16->Delete();
    skinExtractors->Delete();
    skinNormals->Delete();
    skinMapper->Delete();
    skin->Delete();
    aCamera->Delete();
    iren->Delete();
    renWin->Delete();
    aRenderer->Delete();

    return 0;
  }



  vtkVolumereader *vol = vtkVolumeReader::New();
