FOV and Aspect Ratio
- Many issues confront rich media providers when publishing to the
internet or even DVD.
From my perspective the issue of dial up verses broadband is over. I
assume all visitors to my site are on broadband connections or
willing to wait, not my issue.
Given that, I also no longer will put up with small windows for VR
when it calls to a full screen or at least large window. I consider
something about 600 by 480 as a minimum.
But, something that I can't assume now is a 4:3 aspect ratio for the
viewers of my site. Now, a growing number have wide screens. More
like a movie ratio. The movie industry solves this issue by either
cropping the view or using a black box approach to show the full
What do you do to deal with wide format displays? Anything? It does
matter how your VR show up as I guess QT FOV is based solely on the
vertical dimensions, thus leaving the horizontal FOV to "float" based
on a viewers screen. This can create a very inconsistent view.
Does anyone have a script or sprite that adjust the FOV limits and
opening position based on a viewer's screen aspect ratio?

format unless the FOV is drastically reduced.
Fiero Deval has written a script to control the aspect ratio and max size at
which a pano will be displayed.
It is called detectVR.js
It first checks the available plugins and then serves up the pano as
Devalvr, QT, Flash or Java.
You can set full screen *with* a size limit (for viewers with a >19" screen)
AND it will set a limit to the aspect ratio of the pano. Very Cool!
You can check this out on my website www.sphericalpanoramas.com, where most
thumbnails already call the correct devalvr.js to limit the aspect ratio.
You can check this even on a non-widescreen monitor by just squeezing the
full sized pano window to a letterbox.
