Dynamic water

[Gijs]

Nobody to adapt it in the 1,9 version ?

There is no way nor a reason to make it work in 1.9! If we adapt everything to work with older versions, then why would we release new versions?! Just wait for a next release, or if you cannot wait, try CVS...

Cheers,
Gijs

I don't know why but CVS have problem on my mac...
Next release won't be in a while ago, am i right ?

[HHS]

So you have a problem with CVS on MAC?

So why don't you ask here in the right forum for your problem? maybe someone more experienced can help?

If water on a storm made the Nimitz go up and down with ocean waves, that would be sooo awesome. The carrier landings would be a real challenge! Anyways my latest video with some more water reflections from the morning sun on KSFO.

Great video and a nice tutorial for the harrier!

Regarding Nimitz going up and down: I had the same idea, but was stopped by vivian meazza (author Buccaneer, Hunter....) who himself was aboard on a large aircarrier in RL- the Nimitz is so heavy that even large waves doesn't affect much.

But for smaller vessels with helideck it should be possible! The code is laready done and can be find at the small boats at KMTN!

Well, that's not what I've been told by ex-carrier pilots and "rainbow" personnel, but nevermind : swell effect on ships is more affected by volume under water than weight, see Archimedes principle. That's why you can see a supertanker bob up and down on heavy seas (and it weighs several time the weight of the Nimitz. Up to 5 times more heavy with a full load ).
Carriers also bob up and down, and there are several instances of crash on landing , especially at night, with heavy seas because it suddenly went up 30 feet, hitting the plane's underside as it landed.
That's why you start carrier landing training on a painted runway the size of a carrier deck : Field carrier training to mitigate the risks.

Now, a ship the same volume as a carrier but much lighter would of course bob up and down at a much greater oscillation than the carrier, but the carrier still moves up and down, enough that in certain heavy seas, flight ops are impossible.
That such an oscillation is negligible in "normal" (nothing normal about carrier ops situations, with good weather, and the carrier going 25+ knots, as is the norm (it's totally unrealistic to land on a stopped carrier : carriers actually accelerate for flight ops, incurring a greater risk of detection by sonar) is an acceptable simplification for a sim. But it's not reality.

Saying a carrier doesn't roll with the waves is wrong, and against the law of physics : if it floats, it bobs up and down on the waves, period
I'm surprised Vivian would say such a thing.
That said, I can understand him recommending not doing it as it could implicate technical complications : would the hook and wire code support this (how accurate is the trap code, or is it a hack ? etc.), would landing gears behave appropriately, etc.

But most importantly : a carrier floats, thus experiences buoyancy (c.f Archimedes Principle), thus bobs up and down.

Something like that I thought by myself but as I told I was rejected. But you got some real strong issues- maybe we should bring this on the devel-list, so we get this! It would be a neat and realistic feature, which brings also a lot of fun!

Check this video and see what I mean by the carrier moving up and down, around min 3:40-50, thats one of the best videos I have seen about real carrier landings. Just saved it in my favorites so I don't lose it:

Check later on the video the night time.

My video is not like a tutorial for real life (of course!) it's just for fun, remember the Matrix, some rules can be bend, other can be broken

I'm pretty sure the Harrier model in FlightGear needs work, but is fun to fly, and it took me a looooooot of practice to do what you see, I love flight simulators, the idea is to make it look easier than it is. I didn't check at first the yasim FDM on the options and the plane was doing some crazy movements once in the air, yay, so now I know it's a yasim model, very important option.

I was just flying on multiplayer and those helicopters happened to be there when I was recording my video

This is waay off topic. Back on topic, check my sun reflections, I pre selected --timeofday=dawn on my startup for watching the reflection effects, and still have the airport lights on at that time.

You don't have to : you can see the deck go up 10 feet or more at 0:07. I rest my case
Nice (Super ? Not sure) Hornets and Intruders. Thanks for the link,
Cheers !!

[HHS]

Yep- great video! And they are still flying!
We need this feature! (X-Plane has it also- so we must have this!)

The real crazy stuff is the night landings in part 2 : http://www.youtube.com/watch?v=S0yj70Qb ... re=related

These guys and gals are made of the Right Stuff, no doubts.

[planetacancun]

wow check the videos on this page and see what I mean by ocean:

http://code.google.com/p/osgocean/

[Haegemon]

Using the same principle from the volumetric clouds, it's possible to make a volumetric water on the oceans with transparency and reflection. More dificult is to animate the water and make it react to objects moving or sinking on it. If someone knows silent hunter IV can know what i mean.

[planetacancun]

I believe making the water behave like that on FG would possibly open a new world for making vehicles: Virtual exploration of deep underwater. As is stated on their website http://code.google.com/p/osgocean/

"osgOcean was developed as part of an EU funded research initiative called the VENUS project. The VENUS project aims at providing scientific methodologies and technological tools for the virtual exploration of deep underwater archaeology sites."

It would be waaaaay off topic from the game, but also would make the boats (the carrier?) react to water physics correctly, for making realistic landings on the carrier. I wonder about the CPU needs for it to work. Imagine a storm for landing on Nimitz wow.

Guys, guys, guys... quit arguing and look at this thread if you want a pitching deck in FlightGear. It's been done already thanks to Tat.
