What good is calculus if nobody practically uses it.
My pool has an uneven bottom (shallow and deep and varying greatly).

All pool-volume calculators I can find assume a gently sloping bottom (and
therefore use geometric simplifications). I want to try a calculus based
pool volume calculator (that takes the actual shape of the bottom curve
into consideration).

To obtain an accurate pool water volume, I just measured in two dozen
places every few feet the varying depth of an irregularly shaped pool.

I realize, with those numbers, I can draw a side view and then break it
into squares to calculate the volume but there must be a calculus volume
calculator out there that will take the shape of the bottom curves.

But since this is a common need of every pool owner of an irregularly
shaped pool, I wonder if there is a good freeware calculus (not geometry)
pool volume calculator out there that you recommend.

Googling, I found these two Windows freeware volume applications:
* AD Geometrical calculator http://www.filetransit.com/view.php?id=4749
* Volume Calculator
http://www.freewarefiles.com/Volume-...ram_43621.html

And, of course, there are the generic geometric pool-volume calculators
(which all suffer from geometry assumptions):

What good is calculus if nobody uses it?
Do know of any volume calculators that will take the shape of the pool
bottom (measured in two-foot increments) into consideration accurately
without geometric simplification?
