I tried to create water in the non-patched POV-Ray and this is my latest
attempt. I used a height field that has also been created with POV-Ray
using
an average pigment for two rotated marble patterns. The light source and
the
cylinder are used to check the reflection and the shadow.
The results are promising so far. What do you think?

Looks very promising!  I'm not sure if I see flat
spots on the top of some waves or not.  If so I
think you need to tweak the height field to give
generally pointy tops.  Any thoughts on using a
pattern that repeats so this can be animated?

I dont have much time to use POV. So I'm not too familier with the details
The water Looks great!

What did you use for the sky, I like that too. I'm sure it's somthing
simple...

Alan

P.S. did you post this in HTML? with the image inline?

This is very good, competitive with isosurfaces in looks at least I'd say.  The
texturing is
exceptional too.

Yes, I guess you can call it simple. I post it to p.t.s-f .

Only plain text under Netscape with attach file (auto - detect).

Thank you!

Could be that they are flat somehow. I must tweak the 
code a bit. I just played around for a few minutes with
it.
I'm using one height field which is copied 100 times
and where each row is randomly shifted to avoid strong
banding effects.
I guess animating would be difficult. You have generate
a heightfield for each frame ...

Thank you Bob. 
I haven't found time to work with Megapov (and won't in the
next months), therefore I thought about a trick and it worked for me.
I hope I can get to Megapov when everything settles down. I guess
that POV-Ray 3.5 will be out then (and I know this will take some
time ...).


I post the codes to p.t.s-f

How did you manage, that there is no visible break between the hf's?  Doing
landscape scenes I could never avoid that, even if the heightfield was tilable.

Sad fact is that there are visible lines. But look somehow natural (at
least in
this resolution ...).

I had to do a gamma correct, and yes it looks great, even
AWESOME some might say.
