3 Ways To Enjoy 3D Effect Without The Glasses

Whether you are or not a 3D lover, it’s pretty safe to assume that you will not carry around a pair of 3D glasses with you. That’s why we want to share with you how to see 3D effect without any equipment!
Everyday, everywhere you are looking at the world around you with the 3D effect. You might be wearing glasses, but those are probably not 3D glasses :-). So, we’ll count out the normal eye sight. Instead, this topic will cover few techniques that will help us view things in 3D somewhere we are used to not see this way.

3D images or stereoscopic images are one way to go

Stereoscopic images, originally stereograms, are a pair of stereo images that were viewed through a device called stereoscope. Those images are combined in brain to give a depth perception and with that, an illusion of 3D. To see the 3D effect, you don’t need this device, you just need a little practice with you eyes.
There are 2 types of stereoscopic images:

  • PES (parallel eyes stereogram)
  • CES (cross eyes stereogram)

For both of these stereograms, there are techniques that allow you to see 3D effect without any equipment. We’ll start with parallel view technique.
In a stereogram bellow you can see what may seem two of the same images, placed side by side.

They are actually taken from slightly different angles. One image for each eye. To see the depth in these images and perceive the 3D, you’ll have to train your eyes to set the focus. It is easier when stereogram is small in size. Try this:

  • Look at the stereogram above
  • Change the focus from the image by looking through it (and screen) and into the distance
  • This should widen the angle of convergence of the eyes and the images will start to fuse, creating the third image in the middle
  • When the third image appears, try to setting you focus on that one
  • If you see it clearly and feel the depth of the image, you made it – you are viewing an image in 3D without the 3D glasses

This technique is harder for most of the people, so don’t worry and don’t strain your eyes. There is another method that you can try.

In the stereogram below, we switched the position of the images, so left is right and vice versa. This is the cross-eye technique and if you are like me, you’ll find it much easier than the side-by-side technique.

Again, changing the focus is the key, so follow these steps:

  • Take a pen and hold it in a vertical position
  • Put the tip of your pen right between the 2 images
  • Slowly move the pen towards your eyes keeping the focus on the tip of the pen
  • You’ll start to notice that images are fusing, again creating the third image in the middle
  • Now you can put the pen away, but keep your focus there
  • At that point you should be able to see 3D image clearly

With a little practice, you won’t be needing a pen anymore. You will be able to enjoy 3D effect in a matter of seconds.

The Easiest Way to See the 3D Effect

You’ll love this one! No hard work for your eyes. The instructions are easy: sit back and take a look at this wigglegram.

Wigglegram is also created with two 2D images, one for the left and one for the right eye. The trick is that these images are displayed alternately in a way that helps your brain figure out the space and the distances between the objects in the image.

You can easily create all types of 3D images that we mentioned above, with our 3DWiggle software.

Autostereoscopy will help you enjoy 3D effect on displays, without 3D glasses

In the past couple of years, manufacturers introduced us to some innovative technologies that are supposed to revive 3D (TV). They made a display that allows you to see 3D effect, without the 3D glasses.

Autostereoscopy is a method for displaying stereoscopic images without special equipment on the part of the viewer. There is a catch though. The display with this technology can have an eye-tracking system so it can adjust 3D effect based on the position of your eyes. This means that only one person at a time can enjoy the displayed image.

Now, there are many manufacturers that use parallax barrier on their displays. This barrier basically directs the light from the display for each eye, creating an illusion of 3D in your brain. These are bigger displays, so you should be able to watch it with other people. There is a catch here, too though. There are several viewing zones, so be sure your eyes are in one, otherwise you won’t be able to see the 3D effect.

All of the ways we mentioned in this blog post are fun, but we prefer wigglegram. It’s simple and easy to export to social networks. This way, all of our friends can enjoy it, too. If you know another way or have any suggestions regarding seeing 3D effect without the glasses, please share your experience with us. And, of course, if you need any further explanation, feel free to leave a comment bellow.
