The Magic of 3D Images
If you notice the heart picture above, you would assume that the picture looks so plump. However, somehow you would assume that the image is just a picture at the paper flat. Three-dimensional impression it has is just formed because of the color settings. You can easily distinguish them from real objects that exist in front of your eyes.
It is different from the case if you watch the three-dimensional movie you need to use glasses to be able to enjoy the impression of three dimensions. You will feel that the movie you watch is a real incident in front of your eyes.
And do you know that we can estimate the distance of objects because we have two eyes? The scene in front of us will have a slightly different when viewed from the left eye and the right eye. With slight differences, our brains can calculate the distance of objects in front of our eyes. By knowing these facts, then if we shoot a scene from slightly different distances, ie one camera placed next to another camera with a distance of about the distance of left eye and right eye. Then when we see it, if the picture is taken with the left camera just seen with the left eye and the images captured with the right camera is only seen by the right eye, then we will feel that the view of the image as three-dimensional. That is why when we watch the three-dimensional movie we have to wear glasses. Glasses are used to separate the images so that images captured by the left camera is only visible to the left eye and the images captured by the right camera is only visible to the right eye.
Even more amazing is that we can actually manipulate our brains to see the flat image but will look as three dimensional. And we don’t even require glasses to help separate the images. What we need to do is adjust the focal distance of our vision.
Direction of view of our eyes is actually not always straight forward. Direction of view both of our eyes straight ahead will only be appropriate if we see objects at a great distance. For example when we see the stars shining bright at night (wuih, poetic ..), or when we see the clouds that gather at the sky, or all objects that are relatively far away from us. If we look at objects that were located nearby, then the left eye, right eye, and the objects we see, will form a triangle. Well, from the angles in a triangle then the brain will be able to calculate the distance of objects. So in fact our brain has the ability to calculate the trigonometric even before our school 🙂
A very interesting trick is that we can move an object into the paper so the object can still be memorable three dimensions without having to use glasses. The trick is to put the paper between the eye and the object. Then we divide the object into very small parts that we call the pixel. Each pixel of the object moved into the paper by drawing a line from the pixels to the left eye. Crosses between these lines with a line of paper is the pixel position on the paper for the left eye. Do the same thing for the right eye.
Note that the pixel P1 if drawn straight line to the left eye, it will produce a pixel in the paper as a pixel A. Then if a straight line drawn to the right eye, it will produce pixel B in the paper. Unfortunately we can not separate the pixels so that B is not visible to the left eye. Therefore inevitably pixel B when viewed by the left eye also must represent the object pixel, ie pixel P2. Now P2 when viewed from the right eye will be represented by a pixel C in the paper. With the same reason as in the previous process, for the left eye, pixel C is representative of the object pixel in P3. These steps must be performed for all of the object pixels to be transferred to the paper.
To be able to see the results of the transferred image, then we must look at the making process. Note that the paper is between the eye and the object. Thus, when we look at the paper, we should be able to adjust the focus of our eyes to see object behind the paper. In this case we are actually seeing imaginary object which have been moved onto the paper.
When this kind of image was newly discovered, the image was a mystery so people who wanted to saw it must use the power for his own effort to be able to saw. Manufacturing techniques were only said to use computer technology, there is no further information. And as a joke at the time was that these images can only be seen by a clean-hearted person. So friends who have not managed to see it will be said that his heart is not clean. Of course it is only a mere mockery.
Now you can try if your heart is clean or not 🙂 Look at the picture below. I include two helper dots to ease you reach the right focus. If you’ve managed to see this kind of picture, then the next you will not need to use any assistance anymore. In accordance with the techniques of manufacture. True focus occurs when the two dots looks to be three dots.
Do exercises to set the focus of your vision like one of the patient where Patch Adam treated as a new patient did. He pointed out two fingers and asked Patch Adam “how much?” When Patch Adam replied “two”, then he said “stupid, the correct is four”. When Patch Adam met him for the second time, the person then explained that most people only focus on one thing only. He explained that if the focus is behind the finger, the finger will be seen four. Well, actually two fingers can be seen not only four but also can be seen three. Ie if the two middle fingers are piled into one. And that shows the that your focus is correct.
If your focus is correct, then you can see a heart that is so plump and feels so real from the image below. Click the image to enlarge or print off with a reasonable size.
So, is your heart clean enough? 🙂
