TrackIR5 & HUD scaling

[Greb]

Well this is weird. After checking this thread, I looked up at my TV and saw this:

 

MNbWUoUbtC8

 

Edit: Check out the name of the waypoint :D.

 

That's cool!

[ФрогФут]

Or three lasers...

Shame on me! And that is electrooptics engineer!:doh:

 

What i have is that JSF HMD uses LCD with diode lightning, Apache HMD, Eurofighter HUD, BAe HUD for F-16 and Harrier Gr.7 HUD - all use CRT.

Yea, and when you move your head to much backward, HUD "picture" become bigger than projection glass, and you cannot see entire projected data.

 

 

Actually incorrect, if you have your TIR Z axis set to the Zoom in-game, when you move your head back, ALL the projected data on the projection glass STAYS on the projection glass... go ahead n give it a go n see wat happens.

No, in this case it's you who is incorrect. Zoom does not move the pilots head, it adjusts the field of view. Try leaning forward to look over and past the throttle or stick etc with TIR Z mapped to zoom. You will find that you cannot.

[TRoe13]

Actually I am not incorrect. I have never disputed that it actually "moves the pilots head", nor did I say that you can see past your throttle or stick when having the zoom view mapped to TIR Z. I only said it keeps the HUD working properly, here is a video to demonstrate that I just made. http://www.youtube.com/watch?v=6fC4fpNLq2g

But the HUD *is* working properly with TIR Z set to head movement, NOT zooming. See http://forums.eagle.ru/showpost.php?p=1111286&postcount=53

Yes and that's fine, apart from the fact that as many people have tried to explain, that IS NOT what happens when you've move your eyes closer to (or further away from) a real holographic heads up display.

 

What happens in reality is exactly what happens in the sim with TIR mapped as normal. For the americans out there, a hud operates in a very similar (albeit more complicated) way to a holographic rifle sight such as the EOTech, so go and find one of those if you don't have easy access to a modern fighter aircraft.

 

Now this is not to say there is anything at all wrong with mapping the FOV to your TIR Z axis if that is what you prefer, due to poor eye sight etc. But please stop moaning that the hud isn't working properly when in fact it is.

Yes, you are.

There is no way to make the hud bigger irl. Moving your head closer doesn't help (that's how the optics projecting the image are designed). And human eyes lack zoom funtion.

[TRoe13]

So, if I understand you correctly, if a real A-10 pilot pulls his head away from the HUD, everything appears to shrink into the center of the HUD, leaving lots of room all around the outsides of it, and if he moves his head as close as he can to the HUD, then everything gets so big that you can't even read some of the text on it? Because when I have my TIR Z axis mapped to default, that's what happens when I move my head in those directions, and it seems wrong to me.... but oh well, realistic or not, I personally like my TIR Z axis mapped to the zoom view because it keeps my HUD the way I like it, able to be read weather my head is in close, or my head is back sitting on the headrest. Now if they only could combine those two settings, it would be PERFECT for me.

Go Seahawks!

 

Anyway, it's not the HUD I have a hard time seeing. It's what's behind the HUD. I think it's that "sight distance" issue most simulators suffer from.

[Stretch]

That's 100% correct. Try hitting numpad enter instead of mapping TIR Z-axis to zoom, as others have suggested. Numpad enter will reset the FOV to its default and make the HUD more readable. There's a bug in the game where after entering the cockpit, your FOV zooms out to some ridiculously large amount.

Feature, not bug, AFAIK.

I'm quite surprised at the level of confusion here. I think that perhaps too many people have been watching gun cam videos on youtube where the point of view is fixed. Anyone having seen a HUD in real life would realise that the way ED have modelled it is absolutely perfect and the first time bar Black Shark that this has been represented correctly in a desktop simulation.

[Milorg]

X2.

 

And it's probably the most important visual improvement from older sims.

I think it's because noone ever bothered to model this property of HUD displays, and most people haven't seen a hud irl and have no idea about optics, so they kinda assumed that the hud is fixed on the projection glass, and if you move closer it will, naturaly, became 'bigger'.

 

I must admit, I had no idea about this until these threads started poping up. I don't even know if DCS:BS got this thing modeled (shame on me), but I defintely see the benefits. And I love the fact, that I can move around the cockpit, move closer to the hud, and still be able to see all the informations presented on the hud.

[Rusty_M]

I'm sure it is modeled in Black Shark. In fact I think it's modeled in FC2, although 6DoF isn't so you can't really tell. I'm sure I remember something about FC2 mentioning that the HUD is focussed to infinity.

 

When I first saw it happening, it confused me, but it struck me as something that was designed to work that way, and I'd just have to get used to it. I think zooming/changing the FOV makes best sense if you find it hard to read. I know some find that unrealistic as you can't change your FOV in real life, but your real life vision isn't subjected to the limitations of a monitor/tv.
