![]() ![]() Second, using only two forward-pointing fisheye lenses makes the 3D-effect progressively weaker to the sides and approaching zero at the outer left and right horizontal limits of the VR 180 image. Expensive VR 360 setups avoid that in the (most important) horizontal direction by using many cameras and narrower vertical segments with stitching. That is an advantage, but fisheye lenses gradually lose resolution when you move away from the center of the image because the vision field is a half-sphere but is projected on the flat surface of the image sensor. Google addressed the pixel overkill of VR 360 with their VR 180 format, but even that format is wasting pixels in my opinion – for three reasons.įirst, VR180 uses fisheye lenses to cover the entire half-globe vision field, with no stitching of multi-camera images. It is contra productive to good storytelling, only useful for passive documenting. ![]() But video? How often do you look behind you in a video? 360 degree VR video is an enormous waste of pixels, with a very blurred VR world indeed, especially in 3D, where you have to share the available pixels between left and right images.Īlso, showing every angle is unnecessary for the video author who wants to focus attention on what is important. New 6 DOF standalone headsets like Oculus Quest might justify such an extravaganza, as you will probably move in all directions when standing and walking in games. Traditional 360 degree VR is very graphically demanding. See the video in 3D on YouTube VR with any supported VR-set, like Oculus Go/Quest/Rift, Vive or PSVR. This is a scene from one the author´s videos, where you take the passenger´s seat in a sight-seeing flight over one of Norway´s most remote bush strips, where bear and wolves roam. Why narrowing the VR field is a good idea.Į-mail to if you have comments/suggestions to improvements in this blog entry!ĭeclaration: This posting has a CGI (Cranky Geezer-Index) of 20.ģD VR-video give you an immersive you-are-there-experience, even if the format is still lacking resolution. ![]()
