how to free-view 3d images!

Its a simple process that uses no special equipment other than your own 2 eyes.

   [           +*&#@+          ]    [           +*&#@+          ]  

Here are 2 identical sets of characters in brackets. Get at a comfortable viewing distance and cross your eyes while looking at the center     ]    [       part above.

Just viewing the empty space between the brackets and then crossing your eyes creates an illusion that your eyes and brain make. 

Instead of 2 indentical sets of characters there is now a THIRD set of characters that has bumped each of the others out from the center.  If this is not working, or sort of working, try tilting your head slightly left or right to put each of your eyes at the same level. The center image should pop into view and float between the others.

What is happening is that your Left eye has locked-on to the image on the Right, and your Right eye has locked-on to the image on the Left. This does not hurt your eyes. The muscles that pull each of your eyeballs inward, towards your nose, are always working this way, converging your vision unless you are looking at something at a great distance.

All real 3d vision happens at close range.

(We perceive and imagine depth at greater distances using all kinds of clues, like objects overlapping and the way light and colors change with the distance of an object.)

What you are doing is tricking your brain into seeing something artificial.  The optical-processor part of your brain is always working to make sense of what you see with your eyes, trying to recognize the things in the world so you know what it is you're looking at.

If you supply the images, the brain interprets the Left and Right parts into a 3-dimensional picture.

Now try it with a 3d image!
