I know 3D on 2D monitors is possible by using software and cheap 3D glasses (red/blue, etc).
But I want to know if there is a piece of software out there which turns your 2D monitor in a 3D one without the need to use 3D glasses.
It might sound dumb, but I thought about it.
Modern mid to high-end graphics cards are easily capable of delivering a steady 60, 70, or even 120 fps without any problems in most games/applications.
You can simulate 3D by switching from left eye to the right eye and back really really fast (like active 3D).
What if one frame was the left eye and the other the right eye and so on.
So, at 60 fps you would have 30 fps 3D and at 120 fps you would have 60 fps 3D.
Frame 1: left eye
Frame 2: right eye
Frame 3: left eye
Frame 4: right eye
Frame 119: left eye
Frame 120: right eye
I know that each image has to go to the correct eye and stuff, but if it goes fast enough, maybe you won't notice. Or at least I think it is worth trying. Because what happens if it goes so fast, you won't notice it changing and you are practically looking at an already 3D image.
Is there any software which is capable of doing this? And if so, what's the name and where can I find it.
PS: No dumb answers please, I just want to know if this is possible or at least a way to try it.
If both eyes can see both images you will just get the awkward double vision like when you take off the glasses during a 3D movie. The eye smears all the images that it sees together so it will blur the left and right images together and see them both occurring which wouldn't accomplish anything like what you are hoping.
Autostereoscopic(3D without glasses) displays have been made, but are limited in viewing angle and distance. Screens like those on the 3DS require you to be within a certain cone around the screen for things to look proper.
In terms of easy ways to get 3D, red-blue and polarization are by far the easiest and cheapest, a 20" autostereoscopic display would be ridiculously expensive!
There is one other thing that can be done, without glasses, but it is not easy, nor is it all that fun except as a little gimmick 3D experience. You can play a game with split screen 3D. The right side of the screen will have the left eye image, and the left side will have the right image. Now for the trick. You have to cross your eyes so that your right eye sees the left side of the screen head on, and your left eye sees the right side of the screen head on. In your mind, if you can focus this way, you will see the 3D image in full effect. You will also appear to see 2D images on the sides of the 3D effect, because you still see both sides of the screen.
It will be uncomfortable, but I have done it and it works, but ultimately, glasses methods are your best bet.
You shGoogle cardboard is basically a more elegant and smaller setup of what bystander just described, its a pretty neat way to get 3D from a smart phone but is basically an old viewmaster with a smart phone inside. The lenses and divider keep you from needing to cross your eyes to make sense of what you are seeing. https://developers.google.com/cardboard/
