I need estimate the volume and area from a phantom (a acrylic cylinder with 12 holes in cylinder format too).

After the reconstruction by Marching Cubes of the phantom with 12 holes (cilinder format), successfully, i used thevtkMassProperties for measures of volume and surface area. But the volume and area was the extentof the entire cylinder which contains the twelve holes, i.e.,  vtkMassProperties just seeing the cylinder without the holes (I believe because theactors-holes should be targeted or labelled so they can beindependently measured and it will be the goal now). 

Does anyone have an example of how to measure the volume from the many objects separated ?
