[vtkusers] the code always crash

[Ali Habib]

this code for create mesh it always give bug and error that vtkinttype can't
load the elements
I tried to remove Delaunary part , but the same error , I have 4 GB ram ,
and I used GetActualMemorySize( ) to get the actual used RAM
the code is :

 ren1 = gcnew vtk::vtkRenderer();
renwM = r;

renwM::AddRenderer(ren1);

iren::SetRenderWindow(renwM);




   vtk::vtkMarchingCubes ^mcubes = gcnew vtk::vtkMarchingCubes();

mcubes->GetOutput()->ReleaseDataFlagOff();

mcubes->SetInput(VoxelData);

mcubes->SetValue(0, 4);
mcubes->ComputeGradientsOn();

mcubes->Update();

vtk::vtkSmoothPolyDataFilter ^smoother = gcnew
vtk::vtkSmoothPolyDataFilter();

smoother->GetOutput()->ReleaseDataFlagOff();

smoother->SetInput(mcubes->GetOutput());

smoother->SetNumberOfIterations(5);

smoother->SetRelaxationFactor(0.70);

smoother->SetFeatureAngle(70);

smoother->FeatureEdgeSmoothingOn();
smoother->BoundarySmoothingOn();


smoother->Update();

vtk::vtkPolyDataNormals ^normals = gcnew vtk::vtkPolyDataNormals();

normals->GetOutput()->ReleaseDataFlagOff();

normals->SetInput(smoother->GetOutput());

normals->SetFeatureAngle(80);

normals->Update();


   vtk::vtkDelaunay3D ^delaunay4 = gcnew vtkDelaunay3D();

try
{




delaunay4->SetInputConnection(normals->GetOutputPort());

delaunay4->Update();


}

catch(System::Exception ^ex)
{



MessageBox::Show(ex->Message);




}



vtkDataSetMapper ^mapper = gcnew vtk::vtkDataSetMapper();

mapper->SetInputConnection(delaunay4->GetOutputPort());


vtkActor ^actor = gcnew vtk::vtkActor();

actor->SetMapper(mapper);

actor->GetProperty()->SetRepresentationToWireframe();


ren1::AddActor(actor);


renwM::Render();

iren->Initialize();
iren::Enable();


I used getactualmemorysize and numberofcells and numberof point:

at marching, till normal steps I have 23799 kb , 6608388 cells , and 3306508
points ,a ny suggestions please
