[vtkusers] Combining volumes

[Veerapuram Varadhan]

You can use vtkImageAppend.

vtkVolume16Reader* v16 =  vtkVolume16Reader::New();
    v16->SetDataDimensions( 64, 64);
    v16->SetDataByteOrderToLittleEndian();
    v16->SetImageRange( 1, 93);
    v16->SetDataSpacing( 3.2, 3.2, 1.5);
    v16->SetFilePrefix( fname );
    v16->SetDataMask( 0x7fff);
    v16->Update();

vtkVolume16Reader* v16_1 =  vtkVolume16Reader::New();
    v16_1->SetDataDimensions( 64, 64);
    v16_1->SetDataByteOrderToLittleEndian();
    v16_1->SetImageRange( 1, 93);
    v16_1->SetDataSpacing( 3.2, 3.2, 1.5);
    v16_1->SetFilePrefix( fname_1 );
    v16_1->SetDataMask( 0x7fff);
    v16_1->Update();
vtkImageAppend* imageAppend = vtkImageAppend::New();
imageAppend->AddInput (v16->GetOutput());
imageAppend->AddInput (v16_1->GetOutput());
imageAppend->SetAppendAxis (0);
imageAppend->Update();

vtkImageData* pImageData = imageAppend->GetOutput();

pImageData should have the appended volume.  

P.S:- I am not sure whether this will work or not :), as I don't have
vtk in the current box.  Kindly let me know the correct way. :)
