[vtkusers] problems in the volume calculation with vtkMassProperties

[-Daniel-]

Hi,
I try to calculate volumes with vtkMassProperties. 
Here, I noticed the following. Look on the screenshot the sphere (radius of
10) has a volume of 4.178 and the colored Polydata has a volume of 12.454 .

Actually, the sphere should have a much larger volume (visual seen).
Is it because that the colored object is not closed?
How can I calculate the correct volume-result of the colored object ?
