Right here. You said it yourself - no zooming and fisheye views! Care to explain?

I could amuse myself by asking you why I would want to switch to a smaller fov if it didn't actually zoom the view (and make dots bigger, as you claimed), but its just so obvious that you won't take the hint.

As for explaining binoculars and fov - I stand ready, if you are willing.

From the perspective of PHOTOGRAPHY ~


1.3 Barrel and Pin-cushion distortion
The two typical lens distortion that occur are called barrel and pin-cushion distortion. They are named by the effect that they have upon an image, as shown in Figure 1.4. Barrel distortion is found in wide-angle views and it is the result of the squeeze that is applied in order to fit the image in a smaller space. On the other hand, pin-cushion is found in telephoto because of the stretching applied in the image in order to feet the space. The squeezing and the stretching of images vary radially due to the design of the lenses, making these distortions visually most prominent at the image corners and sides.

However... from the perspective of PROJECTION (which is what the image on the monitor is) the opposite applies.

You do realise fisheye is a higher than usual FOV?



Define: usual

I'm sorry that you seem to have forgotten that you made the claim - you need to present your reasoning there.

The opposite applies? Bullshit. Link for THAT claim please.

Oh, and - is a lower fov a zoomed image or not?

What have pin and barell distortion to do with flat screen monitors and games? Or are you SERIOUSLY suggesting that I should be paying attention to the fact that most CRT monitors display a small amount of distortion due to the way the electron gun propagates light onto the (these days flat) glass screen?

you need to understand the difference between capturing an image (photography) and displaying an image on a screen (projection) as decsribed before with regard to the virtual world on a two dimensional surface




and ahhh, yes - your CRT monitor...

It is indeed a LOT harder, and I suspect harder still given that I am using a CRT which tend to have very dark blacks. Spotting a series of black dots/shapes against a dark blue background on a dark monitor is a challenge to say the least, but I also suspect its about practice spotting which I lack, given that offline missions tend to be much more straightforward.

IS A LOWER FOV A ZOOMED VIEW OR NOT!

Answer the question.

Also, provide a link to substantiate lower fov settings in games increasing fisheye (curvilinear) distortion. We are not talking about distortion inherent to CRT monitor projection. We are talking about distortion induced by changes in FOV INGAME. Do not teach what you do not know

Well now isn't that cute, he thinks he's getting a rise out of somebody. That's what you want isn't it?

If you cannot answer the question, it is clear you should not be talking about this subject, so best you move aside, salvage what is left of your reputation and let the reasonable adults that otherwise occupy these forums discuss this without you.

irR4tiOn4L 04-27-2012 10:59 AM

So you got an answer yet, pops?

Didn't think so. But that's fine. I'll end this discussion here. With an explanation of binoculars and FOV.

Quote:

Magnification and field of view work opposite each other in binoculars. The more you magnify, the smaller the viewing area around the subject, while lower magnifications yield larger fields of view. Some applications are best suited for lower magnification with wider views of the surroundings. Field of view is an important factor to consider when selecting a binocular.
Check and mate.

You've already offered the "step aside" thing before... did you forget? I also at the time explained that reasonable men (now add adults) don't resort to derision and denigration... neither do they shout.

Put up what you have regarding your claim of FoV and binoculars being the same - go on, I double double dare you :grin: Your hand has been called

Already did.

Sure, you can keep at it. But I've already thoroughly debased your reputation and argument.

From this point out its pointless for me to debate you any further. If you want to obstruct mature discussion with your immature trolling, that talks volumes. As for reasonable men - they would not step aside from the duty to deride the despicable.

But I will give you an opportunity to redeem yourself and get some brownie points, if you can explain to me the role of the sensor/viewing medium, in conjunction with FOV, to create magnification. Ie - what IS magnification? Do you know?
