[vtkusers] Display tensors for large image

[YaoHaofeng]

Hi,I am trying to display the tensors at each point of a 128*128*64 MRI image, the data is stored in a 9 components vtkFloatArray, I constructed a structuredPoints and pass to glyph3D, but it gives me an error that I am trying to allocate a 1Billion element array, how can I solve that? could somebody please help me on this.Many thanksHere is my code:    vtkFloatArray *arr = vtkFloatArray::New();    arr->SetNumberOfTuples(dimension);    arr->SetNumberOfComponents(9);    for(int i=0; i<dimension; i++) {        arr->InsertTuple(i, in[i]);    }        vtkStructuredPoints *sp = vtkStructuredPoints::New();    int dim[3] = {dx, dy, dz};    sp->SetDimensions(dim);    sp->SetScalarType( VTK_FLOAT);    sp->SetNumberOfScalarComponents(9);    sp->SetSpacing(1.75, 1.75, 2);    sp->SetOrigin(0, 0, 0);        sp->GetPointData()->SetTensors(arr);    arr->Delete();    vtkGlyph3D * glyph = vtkGlyph3D::New();    vtkSphereSource *sphere = vtkSphereSource::New();    sphere->SetRadius(1);    glyph->SetInputConnection(thres->GetOutputPort());    glyph->SetSourceConnection (sphere->GetOutputPort());    glyph->ScalingOff();    vtkPolyData   *output2 = vtkPolyData::New();    output2 = glyph->GetOutput();    vtkCleanPolyData *cleaner = vtkCleanPolyData::New();    cleaner->SetInput(output2);    vtkPolyDataMapper *mapper = vtkPolyDataMapper::New();        mapper->SetInput(cleaner->GetOutput());    vtkActor *streamerActor = vtkActor::New();    streamerActor->SetMapper(mapper);        vtkRenderer *renderer = vtkRenderer::New();    vtkRenderWindow *renWin = vtkRenderWindow::New();    renWin->AddRenderer(renderer);    vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();    iren->SetRenderWindow(renWin);hank
