    Status: Open => Answered

Karol Brzezinski proposed the following answer:
If you do not trust makeCloud (I guess the number of the particles could
be smaller if there is not enough space in predictor), why don't you
count the spheres in the loop:

count = 0
for b in O.bodies: 
    if isinstance(b.shape, Sphere): 
        count +=1 

Approximate size of your cloud in the current shape could be obtained using tesselation wrapper [1]:
TW=TesselationWrapper()
TW.triangulate()    
TW.computeVolumes()
totVolume = 0  
for i in range(count): 
    totVolume += TW.volume(i) 

Don't forget to triangulate and computeVolumes again to 'refresh' the
state (when the shape of your cloud changes).
