Hello,

I think I remember there was a link anywhere in the povray news groups or on the
web how to do a water swirl.

Please can someone point me to it?

Thank you,
Reinhard

Mr. Lohmueller has one at: 
http://www.f-lohmueller.de/pov_tut/backgrnd/p_wat3.htm
and there's another at the short code contest #5: 
http://local.wasp.uwa.edu.au/~pbourke/exhibition/scc5/final.html
Both are using surface normal's, not actual deformed surfaces (Alex 
Kluchikov's is amazing nonetheless).

Not finding something like this for isosurfaces but probably out there 
someplace (perhaps use Alex's function anyway?). Somebody else might know.

that is a normal?!! O_o

just under 512 bytes and I haven't taken the time to look it up... :P

The texture is, I believe, not the swirl object... or am I mistaken???

As said there, lathe is the actual object the normal is put onto.
Likewise, the other example by Lohmueller is also an object (CSG torus 
cylinder) with texture normal.
Both to get the actual whirlpool hole, but otherwise it's all about texture 
not isosurfaces like I first thought when I saw Kluchikov's.
