FOV Setting

Apr 05, 2004 Arolte link
Is it possible to make the FOV value stick to your own setting? I tried changing it to 90 in the wgaf.ini file but it always defaults back to 75 every time I quit Vendetta. If it's not possible now, are there any plans to allow the user to change the default FOV value? I know UT2K3 allows it. Obviously it's within a reasonable range, so as not to distort the screen beyond playability. I believe most FPS games use the 85-90 degree range.

What I'd really like to do is to flatten it out so that it works like a camera. With all the FOVs I've tried, the screen distorts at the edges, making accurate panoramas nearly impossible. What's the FOV for a flat-lens camera?

the FOV for a flat lens camera is basically 0. All FOVs distort the edges at least a little bit. That's the concept of field of view. The only thing that would not distort would be orthographic view and we are not going to add that feature.

We don't save the FOV because if someone was zoomed in when they log off, it would save that and the player may get confused.

Arolte what I do is have an alias set to all the commands I want to do on launch... and then just run it... make it something short and easy. I've got stopping music, turning on frame rate... and a couple other things.

To quote a1k0n from the BUGS forum,>>
"This if off-topic, but no, FOV won't and shouldn't affect the background. It's like using a telescope, not like shooting a probe with a camera on it 1000m in front of you."

Arolte...Using Eldrad's alias to quickly set the FOV and other settings you'd like to keep but get changed to default, sounds like the fix you need for now.

ctishman...I think 'resolution' is the main reason the background distorts at the edges. Try a different setting and see if it makes it any better. I tried different FOV settings to try to get a panorama and it didn't work. The planets and moons still get more oval the further from center they are.

That has nothing to do with the resolution. It's just the way 3d rendering works. It's possible to write pixel shaders to get more of a fisheye lens effect (which is what most cameras produce at a wide fov), but that's slow, and it requires adding a lot more geometry to the scene.

Arolte, just change your -zoom binding. Then hitting and releasing zoom will reset your FOV.

Good call! Thanks a bunch, a1k0n.

FOV does the same thing with a real camera. When you try to get a higher depth of field the edges stretch out.

It's not usually as extreme as it is in Vendetta, but I whatever.

Depth of field on a camera has to do with the focus of objects closer to the lens, and is adjusted by the aperature size. As your depth of field increases, the more you're able to focus on both objects in the foreground as well as in the background. The greatest depth of field allows everything to be in focus, but requires the most light. The area which you're able to see (not in terms of focus) is not affected by depth of field.

Field of vision is a way of measuring the width of your vision, usually controlled by the positioning or curvature of the eyes (or lens). It has less to do with focus and more to do with how much you're able to see. When you're restricted to a certain size, such as the monitor of a computer, distortions will occur as you attempt to squeeze everything into that limited space by increasing the field of vision.
