I am now trying to modify the Medical example coming with VTK.
I cannot understand what is the vtkContourValues for. I use matlab to print out all the 64x64 data in the quater.x file,  no exact value of 500 or 1200 exist. 
It seems that the vtkContourFilter->SetValue(0, 500) just gives a rough guidance to te contour detection, but I cannot find any further details about vtkContourValues.
Can anyone help?
