Do you remember the first time you went out to watch a 3D movie and how excited you were to wear a pair of those special glasses that made you believe that it was pure magic that you were experiencing and what you were seeing on the screen? Yes, that was the first impression of 3D to all – Magic, and it is still the same for many even now.
Nowadays, 3D is not limited just to the movies but we get to experience it in many different fields. We have 3D even at our homes by means of a 3D television and there are the 3D modeling, 3D printers, and many different companies that offer several 3D-related services such as the 3D Rendering Lab. However, do you really know how a 3D tech actually works? Here is a quick guide to understanding the 3D technology.
- 3D technology depends on the principle of binocular disparity called Stereopsis into tricking the human brain to think that it is seeing in depth. Hence, you see different images differently through each eye.
- It also uses the autostereoscopic display to project the different images differently in different spatial directions.
- Additionally, 3D technology makes use of motion parallax, a principle that enables you to think that your background is moving faster than the actual one. This principle creates a more realistic impression on the object.
- In addition, your eyes contribute much to your perception. The ciliary muscles of the eye help you see beyond the normal distance and help you to focus on the object.
- Moreover, a conflict occurs between the convergence of your eyes and its total accommodation capacity. In a regular concept, the convergence of the eye and its accommodation are paired, whereas in 3D these are in conflict, which contributes to the visual magic.
- Further, 3D can be visualized using those special glasses, called the anaglyph glasses. Although these may seem simple in appearance and make, the function is quite extraordinary. The glasses only allow red images to pass to the left eye, while the right eye sees only the cyan images. As a result, you get to see an anaglyph, in simpler words a 3D image.
