The problem with this is that to create the sub-volumes, I assign the data in the field to a value of 1 (or 0 for non-sub-volume spaces). Because of this, I don't see any immediate way to distinguish between isolated sub-volumes.
When I use the Connected module from bonus pack, this assigns a different integer to each isolated surface. At that point, I can use Include to isolate the surfaces. Basically I need to do the same thing with the volumes.
Any ideas?

Have you tried using Include to isolate each sub-volumes by data value and
then pass each sub-volume to Measure?

Subject: [opendx-users] Volume calculation
Hi all.
I have a large continuous 3D field that I transform by 'clipping' it;
basically assigning a 0 to points that fall below a given value and a 1 to
points above that value. This results in a collection of disconnected
volumes. Does anyone have any suggestions on a simple way to calculate the
volume of each separated volume?
I have done this using the Connected module from the Bonus Pack. The
problem here is that this module fails for very highly continuous
surfaces. Also, for the work I am doing, calculating the volume from the
isosurface is not necessarily desirable.
Thanks,
Jonathan
