thanks a lot for ur replys..
When I connect them directly..by writing
mcubes->Getinput(threshold->GetOutput)
it gave me a runtime error..as followed
"ERROR: In \project\VTK v5\VTK v5\Filtering\vtkDemandDrivenPipeline.cxx, line 777
vtkStreamingDemandDrivenPipeline (04520DA0): Input for connection index 0 on input port index 0 for algorithm vtkMarchingCubes(0451EEC0) is of type vtkUnstructuredGrid, but a vtkImageData is required."
any suggestion?

Actually, you shouldn't even need to do what I stated before. Since
vtkUnstructuredGrid is a subclass of vtkDataObject, you can simply pass
the grid directly to the marching cubes (which will see it as a
vtkDataObject) without any problems.
