[REL] REAL U-505 item graphics for slide-out compass

[Oneshot/Onekill]

Beautiful job replicating the compass Hitman. It almost looks like you went and stole the damn thing off U-505 yourself! Downloading and yelling at the maintenance crews to get their buts in gear and install it on my boat ASAP!

a beauty indeed

UPDATE for those interested in knowing what the strange division of the inside circle is....I have found out how it works

The inside circle is in fact a rotating wheel. It represents 10 degrees, and is there for a quicker visual estimate of course change and for increased precision in steering.

How it works:

The inside wheel will do a full turn each time the course is changed 10 degrees, and it can be used for very precise smaller course changes (Even a tenth of a degree). Consider it a sort of "magnification" of the main compass dial, or you can also think as example how your average analog wristwatch works: For each hour mark the small pointer displaces, the large pointer (minutes) does a full turn in the sphere. It works exactly the same but instead of 1 full turn=12 hours small needle/1 hour big needle, these compass dial wheels work as 1 full turn=360º compass rose/10º in the inner wheel.

Here is a video where you can see in minute 2.04 how the inner wheel does a full turn for a 10 degree course change in the main compass wheel:



And here is a link to the present day Anschütz company, which still manufactures gyro repeatesr using the same system of two wheels, large (360º) and small (10º):

Obviously the in-game graphics I provided will NOT work like that, nor can I think of a way of having them work so, therefore we are stuck with a fixed inner dial.

Happy hunting all

Cool! I love the things you learn when you strive to make it accurate. Always something new!

A really good and informative update Hitman

Updated info #2

Aparently the same two dials compass division was used in the US vessels:

The compass card on top of the spider assembly, Figure 34, is clearly visible just below the glass cover of the binnacle. Bearings can be read in tenths and hundredths of a degree. This is made possible by two concentric dials having a 36 to 1 displacement ratio. The entire circumference of the outer dial is divided into ten major divisions to indicate ten degrees of arc so that each major division corresponds to one degree. Each major division is subdivided into tenths, and each tenth is large enough to estimate hundredths. Actual bearings are read against the lubber line fixed on the head. The inner dial carries 36 divisions, each of which represents ten degrees of arc. When the ship makes a complete turn of 360°, the inner dial makes one revolution while the outer dial makes 36 revolutions, or one revolution for every 10° of arc. The speed ratio of the dials is therefore 36 to 1. See sketch on page 28.

Thanks youtube !

I would like central dial to make slightly weathered ...
and i liked icons in the left bottom corner ...

Very VERY nice add-on !
