about the windscreen on the Anton

[ACG_Flyby]

One of my flying mates just posted a link to this video about windscreen refraction of the 190. Thought I'd share it here:

Mind is blown.

Great example for something that is still hotly debated despite the obvious real-world truthfulness of it.

 

Thanks.

Buggerit! That's a bit open and shut, isn't it.

 

Great presentation.

 

So cockpit modellers have been trying to model something impossible for all this time. All because of refraction!

Where's the angry cat? 
Great video, awesome presentation, thanks for the effort!

S!

 

 Nemesis posted this. Great effort to show 3D modelling is more than following blueprints only.

This was very interesting.I had no idea the effect was that large. To handle this correctly in a sim one would have to render the world through each cockpit window seperately, and adjust the final view angle for each based on view direction, glass angle and thickness. It would probabaly be enough to do it for just the front window though.

I've seen many presentation of this issue, but this one is by far the best.

Have to save this link somewhere, this video could be quite handy in the future.

 

Edit: And on a site note, I also have these doorstops!

Great job Nemesis!.

For me the most unexpected and surprising element is that there is no refraction at all when looking through the armoured glass at horizon or rooftop (yellow line) but a lot of refraction where the bar is to hold the glass (green line).

yes, great job. And once again I learn something that only in a real world demonstration would I be able to understand.

 

It will be interesting to see if this changes anything.

There is, but you can't notice it because the object (the house) is too far.

Light crossing the glass reach your eyes with the same angle as if no glass was present. The only refraction effect is that the light ray is shifted down a few cm.

So if an object is close to the glass, you will notice a displacement of the object downward (so for exemple if an object is 1m away and the refraction effect is a 10cm downard shift, the object will be seen atan(1/10) = 5,7° lower). If the object is far, the effect is the same, so the apparent angular displacement will be much lower (an object placed at 50m with the same refraction effect will be seen with an apparent angular displacement of atan(1/500)= 0,1° lower, which is much less noticeable than for the first object.)

You're right. I should have said: 'there is no refraction noticable at all when looking through the armoured glass at horizon or rooftop (yellow line)'

[Rivet]

Wow! You can't really argue with that. Great video and presentation.

[Flack88]

Very well presented.

[ParaB]

That was an excellent presentation.

[I./ZG1_HeTzeR]

Awesome Nemesis!

[Trident_109]

Great presentation and thanks. It does lead me to ask, though, when comparing the cardboard cowling from the video and the bar we have now in the game, would there be a difference in what  we currently see? Or am I not wrong because the glass in the video was shorter than the actual 190 armoured glass?

Hats off to Nemesis.

Because the armor glass has paralel sides the refracted line of sight will be parallel with the line of sight viewed without the glass. Imagine two parallel lines, few centimeters from one another,going straight away from you. Right in front of you, you'll clearly see the difference, but at longer distance, from your point of view, they merge into one:

Hacks!

Very nice and well explained presentation.

Perfect!!! Thanks Nemesis
