ChrisB,
Oh, I more than welcome input. I had thought the thread had gone stale and I
much and just set the two parameters in the pov file. I have them churning on
several machines and just combine the images (after running the rename.bat
file) and they fall into place as pretty as you please. I think having the
file names reflecting the actual second-subsecond frame makes it near bullet
proof.
have stopped the hi-res until I correct it. The ocean comes from Gilles Tran
and he references Marc Jacquier and Christoph Horman for the water aspect.
Basically, he uses a height_field to create a square and then he creates the
SeaSurface based on many of these height_fields properly mirrored to each other
so the transitions line up. For a video to make the wave action I move this
whole field by my wave velocity and the time. I move it for one wave length
and then back it up. The major wave is correctly being moved back, but all the
ocean. It looks good, but unfortunately, the generation for a 720p goes from
solution brewing.
1920x1200 stills show that to advantage. However, there have been some racing
debate that one.
off the helicopter onto the pier and froze at the base of the pier. Yeah, I need
to give a little better acceleration/decelerations at those points.
Sun to moon light transition. Yeah, a little hokey. Did you catch the sun
cinematography excellence, and I like the transition while moving. The
most people have with this image is the vigorous sailing into a lone tropical
island and relaxing by the moon light.
it looks like the surface is crawling. I use a random number generator to
generate the rings in the boards (can see the boards in the hi-res still on the
spray (splashing)?

Hmmm. I'm not sure that adding stealth to the hull of a private yacht is
necessarily a very wise 'improvement'. I think flourescent Green with bright
Orange stripes might give you a higher survival rating on the open ocean
:-)

No I hadn't noticed till you pointed it out. The camera is very close into
the yacht at that point in time and there are lots of artificial lights
around, so my brain just accepted that a light shining on the roof suddenly
went out.

I think this is down to having very fine, but well defined lines (a big
color difference) viewed from a changing camera position. There is a name
for this, but I can't for the life of me think of it. If this is the reason
there are some things you can do with anti-aliasing and jitter to reduce
such effects, but these have quite detrimental render-time overheads.
Alternatively, at this resolution you can't really see the wood-grain effect
anyway, so you might consider using a far simpler pattern for the animated
renders.

Eriban posted a thread entitled 'Rock The Boat (Final)' on 10th July this
year on povray.binaries.images. The Wake is discussed in that thread and
there's a reference to the source in povray.binaries.scene-files. I didn't
try it myself, so I don't know how well it would animate and I don't know
how easy it might be to combine with your heightfield techniques.
Regards,
Chris B.
