To see these images in 3D, you’ll need to use one of freeviewing methods - The cross-eyed view.
The cross-eyed view method uses the right and left images exchanged and views the images cross-eyed with the right eye viewing the left image and vice-versa.
In order to do so, hold up a finger or pencil in front of the image about 1/3 to 1/2 way to the screen. Look at the pencil but concentrate on the doubled images on the screen. Move the pencil closer or further until they overlap to produce three images. The center one should be 3d, but out of focus. Then you need to shift your focus onto the center image without having it jump back to 2d. This is the tricky part, but it works, I tried it myself
Good luck!
