3D technology films and photographs are so popular that they have a more realistic experience than traditional films. They are able to come up with great visuals without limiting the screen.
How 3D technology viewing occurs
Although “binocular vision” is a serious word, it refers to the sight of living beings with two eyes that are on the same level. The specialty of it is that it can detect depth as well as depth, in addition to the 3D view. Even dogs and cats have this ability, but because they cannot see color, it is the human experience.
There is approximately 50 mm to 75 mm gap between the human eyes. As such, every eye sees a slightly different part of the world. To try this, lift a pen, pencil, or other fine objects. Close your eyes and look at it. Now switch eyes. Then the object looks like it is moving against the background.
The two points of view, which we are unwittingly doing in our brain, such as the corresponding angle, geometry; Deeper and better looking. With more than one camera (often a telephoto lens) in modern smartphones, it can detect depth and focus correctly.
The film industry is a pioneer in 3D technology visualization and is rapidly gaining new experience due to its large budget and technical capabilities. There are two ways of using 3D technology for films. Anaglyph and polarized glasses.
The anaglyph method
Traditional 3D anaglyph glasses use one red lens and one blue (cyan colored) lens. There are many other color combinations, such as red and green, but red and blue are often used. The red lens filters the red light, and the red lens filters the blue light. Then the two eyes will see different images.
When the 3D film is projected onto the screen, two images appear. One is red and the other is blue. Since each lens in the mirror has a filter, only one eye can reach. When the two brain images are combined, there is the illusion of a deeper, 3D image.
This method can cause problems such as blurring and blurring of the image color.
This is the method if you are watching movies in a movie theater with colorless glasses. Polarized cell The light wave vibrates only in one plane. The light produced by the sun is not polarized, which means it is made up of light waves that vibrate on different planes. However, it can be converted into polarized light using a polarizing filter.
Small parallel lines of the polarizing filter mirrors (vertical to the left eye and horizontal to the right) are installed. The vertical filters of the lens on the left eye of the mirror we are wearing give the left eye the horizontal illumination when one light rays from the screen are vertical and the other horizontal. Also, the horizontal filter of the right eye lens provides vertical light rays.
There is no color filtering so the color of the film is not hindered. But because of the vertical and horizontal lines, the head is slightly tilted and does not provide smooth vision. To prevent this, spiral lines (spiral filters to one eye, one side and the other, opposite) are now used.
There are other alternatives to television, as movie systems in movie theaters can cost a lot of money to take home. Silver screens are used to reflect light in film screens (which is why the film is called “silver screen”), but television is not. There are several ways to experience 3D technology at home. They are cinematic polarized mirrors, as well as passive and active.
The most common type of active 3D is to wear electronic glasses. The mirrors are synchronized with your TV and they close and filter the light as they close. These shutters move very quickly so the eye does not move. TVs with 3D capabilities have a higher refresh rate. This means that when two images are created on the screen, it takes less time to remove one and bring up the other. Through the glasses, the eyes give one constant image instead of a black screen.
TVs with Passive 3D technology systems do not require expensive mirrors, but one method is to apply a thin, lens-like screen to the TV screen. It is made up of a series of strips with very thin, magnifying lenses that show different perspectives on each eye screen. This technique does not require large, expensive glass, but can limit image quality. Each eye sees only half of the screen at any time. For example, if a screen has 100 pixels, 50 pixels will be sent to the left eye and the other 50 pixels will be magnified and sent to the right eye. In practice, the brain is able to retrieve the entire 100 pixels by holding the two images together.
When shooting 3D movies, you need two cameras nearby. Moving these together and at the same speed, changing the zoom value, Focus does not equal the end result. So camera systems put together are used for this purpose. Similarly, it is not feasible to close the camera when taking close-ups.
Animated films make 3D viewing relatively easy using the computer. For this purpose, the same frame is recorded from two viewing angles. This requires a lot of time and effort. These are filmed movies but have to be played live in 3D computer games. The graphics processor loads too much weight.
This is how to make a 3D mirror
At home, you can easily create a mirror with anaglyph (two-color lenses) and enjoy the 3D experience. You can watch videos of that kind by searching on YouTube as anaglyph.
