Instructions and information on Stereopicturs

How to look a stereopicture?

To consider it is possible as from the monitor, and having printed a picture (it is possible and in black-and-white colour). If you the beginner, try both variants. Many study with printed a picture. For beginners the choice a considered stereopicture is important for the first time also. It is necessary to begin with what pictures?
Choose, that on a picture there were no two-dimensional images, that is that is visible the usual sight, any bright details of registration, additional characters and фоны which supplement a stereopicture plot. The sight all time will "cling" to them and to be focused. So while you the beginner, is better to postpone viewing of such images.

The instruction to viewing:

Way № 1

Place a picture on distance 35-50 see from eyes, look in the picture centre, on do not focus attention to any separate detail of drawing. Weaken eyes, slightly not focusing them (so we look when about something we will reflect, a sight as though through, in anywhere), and then start to focus a sight again, trying to "catch" the three-dimensional image hidden in a picture. It is possible to come nearer and leave thus from the monitor. It is important to hold a head directly as a corner under which you look, plays the important role.

Way №2
It is necessary to come nearer to display on such distance that you could not be focused on a picture. Is better to come nearer closely, having rested a nose :-). The image all will blur. Then slowly delete a head from display (pictures), but a sight do not change. When you will start a head to delete, some fragments of a picture will be close to you, and some to keep away, the image will start to «dance» and be transformed. Look easy, and try not to blink, not to run a sight on a picture. Look attentively at these changes and will see 3D picture. When the image "is caught" it is possible to consider attentively all details of object or several objects.
It is a little trainings and it will be occurs easily and quickly.

If it does not turn out yet it is better to postpone trainings and to allow to eyes to have a rest. Otherwise, eyes can get tired. From it many start to be mistaken, that viewing of stereograms is harmful to sight. Any first physical training of muscles (including eye) causes discomfort. Therefore in all there should be a measure and gradual accustoming.

Statistics

40 % of people, start to see at once the three-dimensional image, 35 more % - having trained and selecting distance and a sight inclination, 20 more % consultation of more skilled person is necessary, and further he will start them to see easily. And only less than 5 % of the population, cannot see the three-dimensional disguised images in connection with some lacks of sight.

What will you see on a stereopicture?

It will be 3D object, отстоящий from a background at some passtoyanii. That is the impression is made, that the object is in the screen, or behind a sheet of paper.
You awake in delight from the seen!
This effect costs trainings, believe!

Advantage of stereograms - Sight Correction!

Stereograms are useful to health! Especially for those who foresees time behind the computer much. It is useful to establish on the computer wall-paper - stereopictures and from time to time to turn a look to them.

Vision of the ciphered three-dimensional images promotes blood circulation improvement, removal of pressure of eye muscles, improvement of work of the device of accommodation. The organism switches all reserves to the control over eyes and nervous cages test the raised loading that improves conductivity of nervous fibres.
Stereopictures name «sports for eyes». Their feature that they force eyes to change a habitual point of focusing, thereby saving up sight and helping to keep its sharpness.

Stereograms. Classes and kinds

Stereosteams - so were called the first stereograms consisting of two images, at combination giving stereoeffect.

Two-coloured stereophotos - the photos made with application of two colour filters. Are considered by means of special two-coloured points.

The stereograms created from casual points (SIRDS - Single Image Random Dot Stereogram), - the usual stereograms created by means of maps of depth and casual points located on algorithm.

Text stereograms (SIRTS - Single Image Random Text Stereogram) - instead of points symbols ASCII.

Animated stereograms - sequence of stereograms with the moving object, united in a video file.

Conditionally effects can be divided on three a kind:

* 3d-surface - On turned out the image is visible тpехмеpная a surface received by тpансфоpмации of a background.
* 3d-object - Turned out the image is 3D object, standing from a background on some distance.
* Combine - Combination of two previous kinds in one. In appeared 3D the image are present both 3D background surfaces, and 3D objects standing from a background on some distance.
