No you can't. your idea to keep the proper field of view, that is through angles from your eyes to the screen, which would generate the in game field of view to be "correct" as you suggested in original posts will HAVE to result in realistic sizes.

Having said that, using 2 different screens (a 17inch diameter one, and a 47inch one) will show a specific object with the EXACT same size on BOTH screens if you maintain the same distance with both screens. You'll just have a VERY RESTRICTED field of view on the 17 inch screen.

yes but pushing a buttom you would switch from realistic size to wide size keeping the effect of varying fov with screen distance in both cases

Well then it seems to me that this specific button would make the whole concept useless now wouldn't it?!
Which brings me back to my first post in this thread:

you would have the feeling of looking through a virtual window with smalling lens or not :)

I must be getting fluent in raaaidalese or something;

What he means is marrying the two ideas - his original changing of the fov, with the 3D window idea - but having his change of fov as a digital, two setting affair controlled by a button, rather than an axis.

When you pressed the button, it would be a little like a zoom out, and as long as the fov is still "connected" to the head tracking position, the impression of depth and viewing "through a window" would remain, though the fov would be much larger so I'm not sure the illusion would still work properly.

yeah something like that I guess. lol xD

yeah thats what i mean

you would have 3 options:

realistic view: one degree of the screen is one dgree of fov

zoomed view one double than the other

wide view: one half than the other

but making sure 6dof keeps the insync fov so distant objects look really distamt by keeping a constant angular size

this effect would be comparable to looking troughg a window with different lenses

your screen wont be a screen a ny more but a window to whatever worlds :)

when they implement this ill buy trackir
