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

* Volume Calculator

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?

You have a nail and are looking for a screwdriver.

Calculus doesn't deal with random measurements. You must first write the
equation for the curve of the bottom.

THEN you can integrate over the range.

If you don't want to do that, look up MONTE CARLO METHOD.
