Not bad... The ripples in your water should be coming from where the water
lands, not where it comes out. The clouds are pretty weird. I really like
your unusual sculptures in the fountain.

The dodecahedrons don't seem to be rotated quite like I would expect. The top
face's are not parallel to the grass, and they don't have a consistent side to
the center of the pool. When I was making a space frame out of many polyhedra
I discovered placing them accurately takes some effort (mental note pre define
some rotations in my polyhedra include file).
Oops got side tracked, and figured it out instead of sending message. Well
the rotation depends on what code you are using to create the dodecahedron.
If you are using my include file I already have it figured out.

Good plan, at present they are simply randomlly rotated (I didn't know what to do
with them. Will look at your macro to work out the maths.
Thanks for the comment. Will update latest version soon.

Are you using my macro?

As I said "If you are using my include file I already have it figured out.", but my
include file isn't that much help at figuring it out. Since I have it figured out
already I might as well post it.

Spiffy. How are you bounding the water?

Water is
blue plane at y=-5
intersection{
a glass plane at y=-0.2
a prism in the shape of the inside of the fountain
}
Quite nice and simple

It appears that your flowing water is composed of spheres. Try switching it
to blobs.

Indeed. hmmm.... Do you think a similar technique will let me bound water in
a bicubic patch fountain I made in spatch?

I have been playing with this all week but I don't know a lot about bicubic
patches. However, so long as there are no problems with bicubic patches and
CSG there should be no problem. Of course, you will need to know the shape of
the space your fountain is fitting into but hey, you designed it.
Let me know if you have any success - This could be useful for some ideas of my
own.
Duncan

Well it was an attempt to to make a bowel in sptach (before I started
messing with lathes in povray) so it's circular with a flat bottom and as it
turns out a cone like thing in the middle. I could probably re-do it as a
union of lathes but doing csg on bicubit patches shouldn't be a problem
since most spatch models are actually unions of several bi-cubic patches.
