I strongly suggest you enlarge the periscope view as big as possible. In my calculate from a normal distance to view computer screen. It's about 1º per 31 pixels (+20%, -10%). Calculate your 57º FOV using how much pixels. Then you know a ship in your periscope small than a ship in real periscope how much. In my modifiction, I even add a 21X zoom level to emulate the same size in human eye retina. And even with that, you still can not get same distinguish ability as using real optic system for your computer do not display pixels in 0.1 mm size.

And I also strongly against using 2 circles style to show binoculars and UZO. It's looks not professional at all.

FOV through an eyepiece is obviously reduced when compared with naked eye. You are mixing here FOV and amount of detail visible or perceivable, which are two different things. I have been testing my results with REAL binoculars this summer, watching REAL ships from the beach and the FOV is correct, although of course the computer screen resolution limits the detail you can perceive (F.e. in thin parts like masts and cables, or edges of the bridge). Then I also have readed many reports and manuals about the periscopes and their limitations, and you can be sure that using them required experience and ability. The amount of detail and size you suggest is in my opinion way better than the one available on real WW2 periscopes, not counting the dirt and humidity condensed in the lense, water reflections and other many variables that cause noticeable distortion to the image.

But again that's only my opinion and how I prefer the game to look like. I did the mod for my personal use but decided to share it in case someone else liked it and hadn't the skills to create his own one. I'm not going to introduce other modifications that those I like, so anyone not satisfied with the optics, just unistall them or modify them (I gave blanket permission for that in the readme in anything related to my own work).

I also have a version with only one circle in the middle, showing the correct vision when the eyes are pressed against the rubber. I will upload it as alternative for those who prefer it

Thanks

Great work, Hitman! Simple and realistic!

I recommend to disable WA support in reality settings if its not done yet. He will report the distance to the closest target only but i think leave it on would spoil the reality purpose of this mod to a certain degree.

To Hitman

There are 2 things: FOV by naked eye and distinguish ability by computer graphics vs real.

You MOD using 425 pixels to represent 57º (or 54.6º) FOV. But from a normal distance, 425 pixels only have 13.7º from player naked eye. (If you don't believe you may measure it youself by using rule). Which mean image is 4X small in player eyes than in captain eyes.

Then what I said is if I enlarge it 4X e.g. using 24X zoom level. So images are look same size from naked eye. But the distinguish ability by computer graphics is still low than real about 1.5X to 2X for pixels normally have a 2.5~3.1mm size not fine enough. Since this case in real is passed by a optical system not by naked eye. I think 1.5X is a good estimate. (Please check binoculars manual)

There are really some day you can get a better distinguish ability from computer graphics. I remember these old days play DOS game like B17 and Aces of the Pacific. The target is very very easy to locate (but very difficult to identify). But now day the SH3 screenshot may just look like a photo. I think it will be some difficult. Although I have to agree with you in particular case like periscope and SH3 lack water reflections my suggestion (e.g. 4X) may be some big. But I don't think it's too big.

Since you have the condition to test (and I don't have). I wish you can do some experiment to check in how much distance you can identify the ship and estimate AOB and compare with the game play. Thanks!

#Hitman

One more issue: NYGM does not allow to choose between pistols. It is locked on magnetic. Is there any way to disable this ability to change them in your mod(locking on Magnetic position)?

Hitman and I discussed this issue by PM a few weeks ago.

Hitman intends to create a revised version of his mod, when he has time, which will remove the magnetic<->impact switch completely, and therefore will create free space to allow better placement of the 'Lock' button.

@General:
In the meantime, of course, it is only necessary to avoid changing the magnetic<->impact switch.

As I've already pointed out on the main NYGM thread, this is a GREAT mod, which I would encourage everyone to try out.

Nope , my mod is using 425 pixels to represent 30º!

Why? First of all because I wanted a realistic 38º FOV for the full scope, and second because to leave all the older lines out I had to reduce the visible FOV to 30º, thus eliminating 4º on each side.

But since REAL german periscopes had an EFFECTIVE field of view of around 30º due to image and colour DISTORTION on the borders, I thought it was not hugely important.

I understand your reasoning and critics but as with any mod, a compromise has to be made, and I chose my own option.

Enlarging the whole thing -albeit still keeping the 30º FOV- would be another option to achieve better image quality but I lack the time to do it and since my screen is 21 inch running a res of 1600x1050 I don't really need it, as the vision is good enough.

30º you mean 1X zoom. But in fact it's 1.5X zoom. Why you use a binoculars?

I've also noticed that there is no TDC ON/OFF button available at both scopes.So when I finally get:range, speed, distance I have to press TDC on the left, turn it ON and set the values or go to scopes set values there and get back to TDC to turn it off(I'm using wazoo wheel method at 100% realism). Is there any way to put a tiny ON/OFF button in scopes view?

What button do you mean? :hmm:

There is a grey button in the upper left corner of the TDC in all stations for locking it. You can manually input values in the dials and then lock it again.

I never said it was 1x, it is obviously 1,5x. At high power zoom it is /4 of that figure.

Well, because real U-Boat periscopes are not easy to find in stores near my home, you know, so the best next thing I can have to get the proper feeling of what it is to look through optics is a binocular.

In my "version" you cannot input any values to the dials in the scope view. First you have to go to TDC menu(the one with map) turn it on and than put the values.






In order to change values marked yellow(target speed and range) I have to go into TDC and press ON button(it is set to OFF by default)

@krantz:

i guess you can enable/disable manual input into TDC from periscope by pressing Ctrl-T.....
