[vtkusers] Need to save vtkVolume as an 3D image

[Sahan Ranasinghe]

Dear Dean,

This is the related part of my code. dataset is the read image series. you
mean I nead to write dataset as image series. Am i right?

vtkImageContinuousErode3D *dilate=vtkImageContinuousErode3D::New();
dilate->SetInput(dataset);
dilate->SetKernelSize(3,3,1);


vtkRenderer *renderer = vtkRenderer::New();

vtkVolumeRayCastMIPFunction *mip=vtkVolumeRayCastMIPFunction::New();
 vtkFixedPointVolumeRayCastMapper
*mapper=vtkFixedPointVolumeRayCastMapper::New();
mapper->SetInput(dilate->GetOutput());
mapper->SetSampleDistance(0.5);
mapper->Update();

vtkPiecewiseFunction *opacity=vtkPiecewiseFunction::New();
opacity->AddPoint(0,0.0);
opacity->AddPoint(1,1.0);

vtkVolumeProperty *property=vtkVolumeProperty::New();
property->IndependentComponentsOff();
property->SetScalarOpacity(opacity);

vtkVolume *volume=vtkVolume::New();
volume->SetMapper(mapper);
volume->SetProperty(property);
volume->Update();

Thank you for your help.

Regards,
Sahan
