I made a fountain with sPatch and now wish to put water in the basin.
However I do not know what type of object would be betst to use
(superellipsoid, extrusion, a primitave, etc.) for the water nor do I
know how to confine that object to with in the basin of the fountain
once I've created it.

Since you are familiar with sPatch, can't you make the water in sPatch
as well? Just an idea anyway. You can try to CSG the union of patches
sPatch exports, it may or may not work -- it shouldn't by POV laws but
there are hacks to it and I don't know how MegaPOV will treat it.

  What's a primitave?

-- 
main(i,_){for(_?--i,main(i+2,"FhhQHFIJD|FQTITFN]zRFHhhTBFHhhTBFysdB"[i]

When you look at the POV output from spatch you'll be able to work out
the size of the object you're working with, alternatively expirement 
with a green sphere or something.

For the water, many people seem to get really good results with Chris 
Colefax's spray macro, you can find a link to Chris's site via the 
links page at http://www.povray.org

I'll keep that in mind.

I was planing on using that for spray any way. Will it also do the water 
in the basin?

I'm actually not that good with sPatch my fountain was origionally 
supposed to be a bowel. That makes sense about not being able to CSG it. 
I'll proabably hack it into looking right by changing scale and stuff 
like that.

Possibly I suppose, although I've only used a separate object for water pools
(except for a stream I did once).  I'd think you would need a real long "life"
for the spray to get it to collect.  I haven't had much success in keeping the
fake liquid around very long but with a continual flow I would think so.

Was this in an animation, because I was planning on doing a still at 
least for now. BTW what object do you normally use for water becasue I'm 
baffled as to what I should use so far I've come up with a taurus or 
cylender with a whole in it modified by the wave or ripple normal.

The Liquid Spray include file is really designed for particle sprays, and
although it will create puddles on flat surfaces it doesn't (yet?) allow you
to fill containers with liquid.

Instead, I might back-up Peter's suggestion of modelling the flat surface of
the liquid in sPatch as well, or perhaps a simple disc would be enough.
Either way, unless you want to give the water an interior for fading or
media, it should be enough just to model the surface with a suitable texture
for ripples and such.
