Looking into the reflector gunsight

[ACG_Dickie]

Something that has always bothered me in all of the IL2 series is when one leans into the gunsight and the recticle shrinks against the sight itself.  Surely this is incorrect?  Why would the reflected light on the glass shrink to scale just because you get nearer to it?

 

The effect I refer to is at 1.55 in this video with Loft demonstrating.  Rather than remain in scale with what it is reflecting from it appears to shrink and move into the background.

Loft indicates that this is correct,  that "the size is focused it infinity", it is a 'system', but I believe that this is incorrect.

 

Here is a real gunsight as you move your head toward it, it remains in scale as one would expect if you moved your own face toward something, even if it is a reflection.

I appreciate this is a pre-alpha, I hope you can amend this in time for release.

Thanks

I understand your concern Osprey, one thing to notice though, the camera in that video wasnt near the gunsight,the person holding it just zoomed in and the zoomed out, maybe that is why it looks bigger.

[ACG_Dickie]

That doesn't matter.  If you moved your head closer to a real gunsight the reflection isn't going to scale down as in the demonstration which was given in the first video,  or how it behaves in past sims.

??? the reticule is not shrinking, it's the gunsight that is getting bigger as you get closer. This is how it should be. The reticule is projected in the distance, so you don't need to focus your eyes when looking at a bogey. That's the whole point of the reflector sight? Maybe I don't see it right in the youtube movie....

 

This will explain better than I do:

It does matter Osprey, you can see from both videos Ross posted that while zooming in the illuminated reticle doesnt not seem to get smaller but when the camera actually moves closer it then seems to get smaller. I used the word seem because as Vader pointed out I think there is an optical illusion going on and the reticle doesnt get smaller.

I think here is not real gunsight but selfmade construction for handmade cockpit.

This is perfect and I can see now that i misunderstood something,  I'd like to get my hands on one and understand it better.

That looks great Osprey!That thing looks more complex than what I thought they would be.Thanks for sharing.

Loft even says in Hooves's video that the gunsight doesn't change size. It's the same way with the reflector sights in RoF (yes, there were reflector sights in WWI).

The video don´t show a real WWII gun sight , It think ...

This cockpit and gun sight its builded for games

Stern supplies some vids,   months late mind you

When I studied physics in university we happened to study gunsight reflectors as they are a good example of optics and the physics of light. The behaviour of the reticle we have in the game is in fact correct. It may seem counter intuitive ,but let me assure you the size of the reticle does not change as you move closer.

 

" the principle of the collimater is that a reticle, fairly close  to the observer, can be optically transferred to a position infinitely distant from the observer"... to put it simply...  Moving six inches closer to infinity does not make it look any closer.

 

The real advantage of this is that you can look through the reflector sight from the right or from the left and the reticle will still be straight ahead.  I play the game in 3d and the gun sight appears to float in front of my screen the reticle how ever seems to be off in the distance beyond the prop. I was pleasantly surprised to see this in Rise of Flight the first time I played it in 3d. As this is what I was taught  is should  look like.

 

The devs have indeed done their homework

I just pulled out my EoTech sight (hud design) and it's the exact same way. Circle and dot and if you can see it anywhere in the HUD glass you can shoot and the projectiles will land where you have the dot.
