FREE VIEWING STEREO

There are two ways to see stereo pairs with the unaided eyes:
PARALLEL and CROSS EYED viewing.

Learn to Free View! It's fun, but don't try too hard!


CROSS VIEWING

This is a simple stereo pair. If you'd like to learn how to see the 3D, follow these directions:

PATIENCE IS THE KEY!

Hold one finger in front of your monitor, about a foot in front of the red blocks. If you are focused on the monitor, you should notice your finger is "doubled" (two ghost fingers "floating" in front of the monitor). If you now focus on your finger, you should notice that the blocks have doubled. The object is to hold the gaze (or focus) of your eyes on the finger, EVEN AFTER YOU'VE SLOWLY PULLED YOUR FINGER AWAY (as if the finger were still there)! This should leave you with doubled red blocks - 4 of them- ideally you want to "lock into" the center 2 so that they come together and form one: a 3D image! When you are doing it correctly you'll see the white dot floating above the red field, with 2 "ghost blocks" on either side. In essence, the right eye looks at the left block, the left at the right.
Images on this site are set up for cross-viewing because image size is not a factor.


PARALLEL VIEWING

This is a simple stereo pair. If you'd like to learn how to see the 3D, follow these directions:

PATIENCE IS THE KEY!

Instead of crossing our eyes, we will train our eyes to look straight ahead. Normally, when we look at the computer screen, both our eyes are looking at the exact same spot- our eyes converge on that spot. The only time both are eyes are looking straight ahead is when we're looking at something far away. To see 3D in PARALLEL, our eyes must be looking straight ahead, even though we're focused on the computer screen. This is easier for some than others- but most can do it with some time and patience (neither of which is readily available!) The easiest method is to let your eyes relax, stare at the two red blocks... now move toward the screen- closer and closer- don't try to look AT the blocks (look through them), until they double up and the middle two white dots MERGE INTO ONE: hold that gaze! Try to back away, locking the gaze...there should be 3 white dots- the middle one should be in 3D- receding into the red field. In essence, the left eye looks at the left block, the right at the right.
With parallel viewing, the maximum width of each image is generally the average interocular distance (65mm).
