Notes:
1) There are slight changes in the scopes to achieve the accuracy needed to use the AOB wheel.

2) The Axis scopes are a compromise of HardCode, which I can do nothing about, and information that is available. Updates will occur as info becomes available.

3) The AOBWheel_Pdfs.zip contains the necessary user documentation for JSGME installation, or manual installation.

4) Of course you have to print the wheel PLATE BMP files and make the wheel yourself. A good fun exercise and the more precise you are, the more accurate it'll be.

IMPORTANT NOTE
The one file that most used in mods is the Cameras.dat file.
The ManualScopeScaling.pdf contains simple instructions how to change this manually, if you have other mods that use this file.

Enjoy and complain to me if 'it doesn't blow your hair back'..

For the people who want this for SH3, I have to get hold of a ship length table, preferably in Excel format.

Hey Vanjast - dying to get to try this, but would you be kind to explain why the changes to min and max zoom level are as they are. As you know i have roamed quite a bit with getting realistic zoom levels and angular angles in the periscope sight for about 1 year ago. I'd like to know what you found out here

There are 3 things (that I've found) that have to be matched.

- The Bearing Indicator at the top of the scopes
- The zoom levels
- the Scope Gradations.

1) The Bearing indicator is hardcoded, and uses the Bearing.dds image file. One cannot do much about this AFAIK, so I start at this point.

2) I put an Iowa class ship in front of me at 1Nm and turned the scope to get a 'bearing difference' (BD) on the bow and stern. At a range of 1Nm the BD had to be X degrees. I adjusted the zoom level to obtain the X degrees.

3)After that it was a matter of drawing the gradations on the scopes to match Zoom and BDs. Placing the scope vertical centreline midway on the ship length, I positioned the gradations to match the ship length. This would be 1x Zoom

4)Next was to make sure the 4x zoom mode was accurate by adjusting the 4x zoom level factor. Checking this so the gradations match 1x mode

4)To check the gradations at various zoom levels, I would turn the scope and do random bearing measurements on parts of the ship. This all looked OK.

5) Lastly was to randomly do the same checks on a few other boats in the game. All looked OK

6) With the obscope Sextant set the zoom level so as to be able to fit 60 degrees vertical. I made this zoom level 0.5x. The zoom factor numbers do not match the 1x mode due to the fisheye lens effect where stretching occurs as you move away from the centre point. I think this can be corrected for by adjusting your eye distance factor which I must find to play with, but for now this works.
This 0.5x mode is only accurate for Sextant measurements, although it is still accurate for ship measurements if you have the ship centred (locked),

This reminds me to put up a 'ship dimension' PDf file which I used.... Forgot about this

Edt: The big problem is that there is only 1 Cameras.dat file for both Allied and Axis views. This is not bad for the fleet boats and the game was originally geared for this, but it's not good for the UBoat/Japanese boats as their scopes are slightly different. Playing with the zoom factors will mess things up for either side, as explained above.

What this little thing does, is introduce a necessity for proper accuracy in the 'measuring equipment' (scope scaling and timing). Without this the Wheel is all but useless (It could make a nice frizzbee

)

I'd imagine back then, a lot of effort must have gone into that disk, some say they've seen hanging around the WO's neck. For me it's been about 5 weeks parttime work, that is, most of my spare time.

For now it's rest time until I get inspiration (ahhhh!!! hooters bar, topless babes dancing on a bar, streaking girls at a cricket match.....

) ..I digress... ahemm.. you know what I mean

Hey Vanjast

why do you call it an AOB wheel, when it's for getting a speed estimate?
