Suresh,

	You understand that you are trying to go from a structured ImageData to 
an unstructured PolyData ? There is no direct conversion from one to the 
other. You need to redefine your real problem. Maybe a you are missing 
the contour detection (Marching Cubes). And BTW there is a 
vtkSTLReader/Writer in VTK.
