So I know the difference between VR and 3D, but it's the 3D part that has me confused. As a kids 3D to me was that you had to wear the blue and red glasses to watch a movie that was recorded by two camera one with a blue tint off set by the one in red tint (pretty much). I made pictures in 3D with a still camera and using special software the combine the two image as one and you just put on your glass. Here's and example of an image. https://s-media-cache-ak0.pinimg.com/originals/c6/fb/24/c6fb24d43b1083259ab644edebe0a529.jpg
Now when it comes to VR I see several places that offer 3D movies for the VR. When I check these out the movies are split into two screen, one of the left and one on the right. Doesn't most of the VR apps out there already split the screen once you play the videos?
In other words how to I take my movies and convert them in 3D? Even YouTube offer videos in 3D for people with VR headsets.
