Sniper class scopes

[firebugs]

Did some playing around offline today and found this. The Sniper scopes in this game (all countries) have 2.517x optical zoom.

Historically;

APX MLE 21- 3x zoom

No.32- 3.5x zoom

Zf39- 4x zoom

Here are some screens for the No.32 (british) scope. I'll do the Zf39 and APX Mle 21 tonight or tomorrow.

And as proof that my method of testing is correct, here is a real life series of pictures, taken from the same point. One with just the camera, the other with the camera looking through a scope marked as 10x.

If I had to guess I would say the only difference between the scopes of the three countries in BE is the art. The code behind them is probably the same. Would be nice to have accurate optics modelled, but not sure if thisis possible atm (resource issues and what not).

Of course, I'm likely wrong here, in which case hopefully it's a relatively simple fix.

Good post.

All scope and gunsight will need some fix. Where i can find your work to check it. Are you using .follow command to set right distance when u couting pixels ?

The distance isn't important when counting relative width.. it's an angular measure, like Mils or degrees.

What does matter is that the object is at the same distance for both pictures, which it was, I backed the infantryman into the same corner on the offline spawn building.

Now how I make these may be off a slightly because I have to estimate that I'm 63 meters away (2.517/4=.62925 X 100m= 62.925m). I'm using the same scope at a closer range to give the illusion of more zoom.

Distance is good for sizing of foresight. IMHO scope forsight is to big.

Brit scope = 4.19 zoom in game

Except you need to consider the "no zoom" view is actually "zoomed out" because we currently have a 90 deg FOV shoved into a much smaller actual width. The "no zoom" view should be the same as looking through iron sights.

Yeah, what he said. You'll notice that the riflemen, ATR, LMG, airplane tailgunners, and airplane pilot gunsights, and many others all zoom in to the same level, which is considered the true "naked eye" AKA 1x zoom.

They "zoom out" normal, un-aimed view in order to get a decent field of view while just running around.

The data defines the zoom level as 4x.

This is the same for all rifle scopes.

That's sorta true but you can't just look at numbers here as the screen isn't a true simulation of perception.

In beta for instance we decreased the aim FOV to bring the world a little closer and it feels much more like what you would see in an iron sight.

So I hear...can't wait.

by definition then, shouldn't the "4x" scopes be zoomed in 4 times as much?

I don't mean to argue, but it seems strange to me that a 4x scope is not 4x zoomed in from what is considered "what you would see in an iron sight.", because with real optics, that's how it is.

I guess the game code sets everything from the default (lowered) view (which makes sense). Therefore, iron sights is a certain zoom level and then optics are a higher zoom level.

Rifle aim has a FOV of 45 degrees. This has been changed to 30 in the Beta.

I'm not sure on how this is calculated but I believe it is still based on the 4:3 screens from when the code was written though we now draw it based on the vertical to take account of wide and ultra wide resolutions.

In the old day if you had a widescreen then your view was stretched.

Looking through the scope calls a gunsight file.

This calls a mag number as well as defines the lines on the screen. I have no idea how this affects things. I'll try and ask Martini when he gets back.

But baseline I don't know the intricacies on how it works but I assume:

1) the grognard who wrote this stuff probably got it roughly right since he was even more anal than firebugs about this stuff (he made our infantry have brain oxygen level FFS)

2) I wouldn't assume that aim FOV is in anyway representative of 1x or that scope view is a magnification on that

good to know. answered a few questions I've had over the years right here. Thanks!
