VR zoom...

[markturner1960]

Hi, how does the VR zoom work within DCS? I was expecting that like zooming in on anything, you end up looking at the same pixels, from closer, so if anything, the detail should be less clear, but larger? However, in VR zooming in, I find that its really much clearer and a way better picture than zoomed out.....so why is that?

You can bind vr zoom to any key or button. Just zooms in on whatever you’re looking at. Look for zoom options in control adjustments.

Thanks, but you misunderstood my question, I know how to bind it and have it working and set up properly....I wanted to know why the VR image was so much much clearer and better when zoomed in. For example, if you zoom in on a digital picture, the more you zoom, the more pixellated it gets....why does the view in VR not behave like this, after all its the same principle, a set number of pixels being generated to fill the view....?

Please note the binding is in the UI section of Control.

To me, the zoom is more like using binoculars or a small telescope.

Probably why the second level of VR Zoom is referred to as "Spyglass Zoom".

Not really same principle. When you zoom in DCS, it's not 'enlarging' from the rendered unzoomed view like zooming in on a digital picture. It's setting new camera parameters for the renderer, which is refreshing every frame. Better analogy might be zooming in on a vector image (ex: google maps) - it doesn't matter how far you zoom, because the source data only becomes 'pixelized' when it's time to draw it to the display.

the zoom only deals with a faction of the visual field and therefore less demanding it is to render it.

Actually, VR zoom in DCS is like zooming in on a digital picture.  The perspective doesn't change.  Pause, look at a distant tree in relation to your cockpit frame.  Then do VR zoom, the aspect between the tree and your cockpit frame doesn't change with VR zoom.  But if you move your head forward and back, you'll see that the aspect between the two will change.

Using "Zoom" on a camera or binocular is like moving your head forward.  Then why is DCS like this?  I don't think it's to save render resource as @DerekSpeare said.  It doesn't use any more resource enlarging vs changing camera focal length.  I think they did it this way because it's simpler to implement.

To OP, why doesn't it get blurry?  VR Zoom is "supposed to" simulate looking through binocular.  You'll notice that it not only enlarges picture but increases view distance.

My main point was the vector vs raster part. As in, it's not just scaling up the unzoomed frame where it would become pixelated like zooming a digital picture. It's re-rendering it with different camera settings, where there is no pixelation, a la zooming in google maps.

I do wish they'd upgrade how they do the zoom so it doesn't flatten the image like you are discussing.

DCS simulates an optical zoom and so would not pixelate the image.

There is a nasty problem with distortion when moving your head though.

EDIT: nasty = nausea inducing

What's your Visibility Range? Anything below High will make you see much more details when zoomed, because all it does is moving camera closer.
