Interesting to read all this. I think I`ll check the wave speed on my own right now - I found the original one a bit too fast indeed. And if there was no bowspray sound, well... I can survive this :)

By the way I`ll check IF slowing the waves down has an impact on fps. :hmm:

The waterspeed setting is listed under the heading "Water Droplets". Seems that this would not affect ocean waves? It might, instead, affect the speed of the water spray from a boat's wake or maybe the blurry effect of water draining off of the glass of the periscope? Just wondering.

I like that program too, but every time I make a change, it leaves a ".bak" file there?? Why? And can it be taken away?

/Rulle

oups i had missed that one.
So yes you can change that .bak file
you have to set up the "backup" file directory
in "Advanded/configuration..."
you have a "Backup" setting and you can give the
default backup directory.
You can use something like
C:\WINNT\TEMP\
or any other directory you use to store temporary files.

hope it helps

I thought it was to do with the wavelap rate on the periscope . I must have been imagining it .

I suppose there`s a mod for the periscope water drops et c., but that`s other thing.
Interesting issue: I`ll check if I can set the speed to, let`s say, 1.5
As for now, 2 is still slightly too fast for me while 1 seems a bit too slow.

Hi!

The speed of a wave through the water is a function of the distance between wave peaks. Experimental data suggests the minimum ratio of wavelength to wave height is 7:1. See this site, among others, for the gory details. You can also "ask Dr. Google" about "ocean wave speed." ;)

I have no idea whether ocean wave physics are implemented in SH3, but the existence of variables such as "waterspeed" indicate the dynamic (i.e., realistic) relationship between wave height and wave speed, like that between a submarine's depth and its minimum sonar detection range, is modeled in SH3 as a constant.

It may be possible to estimate the maximum realistic in-game wavelength by doing the following:
  • - Compare the peak-to-peak distance of in-game big waves to the length (or height) of your u-boat to estimate the wavelength. Use the fathometer to obtain the depth under keel (you'll need it for the calculations).
    - Use the equations found here to estimate the realistic wave "speed" for waves of that wavelength.
    - Find the relationship between the value of "waterspeed" and the velocity of wave peaks: measure the peak-to-peak wavelength of a wave as it passes by your non-moving u-boat, and the time that passes between those two wave peaks (see how handy that periscope/UZO stopwatch is!) as you try different values for the "waterspeed" variable.
    - Set the "waterspeed" to give the appropriate meters/second of wave velocity given the peak-to-peak distance of the big waves
FWIW, the tanker USS Ramapo observed the largest, reliably reported mid-ocean wave in 1933, during a storm in the North Pacific Ocean. The wave's height (peak to trough) was estimated to be 34 meters: the Ramapo survived because it was short enough to ride over the waves (remember the ratio of wave height to wave length) instead of plowing through (or under) them.

Yes, that´s the one. It costs 39.95USD.
