3D technology films and photos are so popular because they provide a more realistic experience than traditional shows. They can 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 remain on the same level. The specialty of it is that it can detect depth, in addition to the width and width, it gives a 3D view. Even dogs and cats have this ability, but because they cannot see the color, they are more experienced than humans.
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 excellent objects. Close one eye 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 visualization, and its rapidly increasing cost savings and technical capabilities are generating new experiences. 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 every 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 more in-depth, 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 cinema with colored glasses. Polarized cell The light wave vibrates only in one plane. The light produced by the sun is not polarized, which means that it is made up of light waves that vibrate at different levels. 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 does not hinder it. The head is slightly tilted because of the vertical and horizontal lines and does not provide a smooth vision. To prevent this, spiral lines (spiral filters to one eye, one side, and the opposite) are now used.
There are other alternatives to television, as movie systems in movie theaters have to spend vast amounts of money to take them 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. These are cinematic polarized mirrors, as well as both passive and passive modes.
The most common type of active 3D is to wear electronic glasses. The mirrors are synchronized with your TV, and they close and open and filter the light. These shutters move very quickly, so the eye cannot see. 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 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 fragile, 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, the 50 pixels will be magnified and sent to the left eye, while the other 50 pixels will be magnified and sent to the right eye. In practice, the brain can recreate 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 result. So the camera systems that are put together are used for this purpose. Similarly, it is not feasible to close the camera when taking close-ups, as a mirror can capture a second camera and create a 3D vision.
Animated films make 3D viewing relatively easy using the computer. For this purpose, the same frame is recorded from two 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 technology 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.
- A cardboard
- Transparent tape
- Glasses format (Download as PDF (72KB))
- Red and Blue Cellophane Paper (available in stores)
Print out the downloaded PDF and cut it along its edges (including the eyes). Cut the cellophane paper slightly larger than that size and place it on the sides of the mirror with tape. Because of its large cut, the tape can be restrained so as not to disturb the vision. Now tape the earphone to the middle section. If necessary, replace the cardboard and cellophane with an old sunglass lens and remove it with red and blue marker pens.
