Another vtkMassProperties Question...

[Jennifer Hare (CICC/HPC) <jen>]

I've been playing around with vtkMassProperties since my first message,
so now I have a more detailed question....

Could someone please explain the difference between the following methods
in vtkMassProperties:

	GetVolume
	GetVolumeX
	GetVolumeY
	GetVolumeZ

I used GetVolume for a sphere and it returned the volume of that sphere.
I used GetVolume for a rectangular block, but it did not return the correct
volume of that block.  I then used GetVolumeZ for the rectangular block and 
it did return the correct volume of that block.  Does the method for finding
the volume depend on the data?  And if so, what are the dependencies?  I need
to find something (or need to write something) that will find the volume of 
any closed isosurface.

Thanks,

Jen
