3D Eyeware Produce three-dimensional sense
Main 3D technology type
Spectral method: polarized 3D technology
Polarization 3D technology, also known as polarized 3D technology, English for the Polarization 3D, with the use of passive polarized glasses, because the screen will not appear flashing so commonly known as "no flash" 3D. Polarizing 3D technology image effect is better than the color difference, and the cost of glasses is not too high, the current cinema is also used in such a technology, but the display device brightness requirements are higher.
Polarized 3D advantages include: no flicker screen, light weight glasses. But it also has shortcomings, one is to watch the angle requirements, because it produces three-dimensional sense of the principle is the use of light refraction angle, so when the angle deviation, it will produce the screen ghosting. While the second major drawback is the reduction in image resolution. As most of the current mainstream polarized 3D display / TV is to take the original image separation of the way, so its clarity will be halved.
Timeshare: Active Shutter 3D Technology
Active Shutter 3D technology, English for Active Shutter 3D, with active shutter 3D glasses. This 3D technology in the TV and the projector above the most widely used, relatively large resources, and the image is excellent, by many manufacturers respected and adopted, but the matching price of 3D glasses higher.
The biggest advantage of active shutter technology is that the picture quality is completely intact, and the viewing angle is good. But its shortcomings are many: the first is the cost of hardware, no matter which program, monitors, glasses and other equipment prices are the most expensive home 3D equipment. In addition, the principle of the shutter-type 3D technology, when the surrounding light source, the screen appears to flicker. Finally, the shutter-type 3D requires the transmitter and receiver, which directly increases the complexity of installation, setup and use, and the receiver is usually placed on the glasses, so the weight is inevitably increased, increasing the user's physical burden. Static 3D
Static 3D is usually in the form of pictures or photos
Three-dimensional painting principle is based on the reverse use of perspective, known as the principle of anti-perspective. Is the drawing of objects through a specific point of view, according to the visual imaging of the reverse projection screen to the picture carrier of a painting technique, the basis of the perspective of a high demand. Need to understand the principle of perspective after easy to understand the use of it. Dynamic 3D
Dynamic 3D can be divided into "true", "false" 3D two cases
For example, we sometimes see a lot of interesting animations on the Internet, where objects are often ready to come out.
These animations are loved, but they can only be "false 3D". The key is the two lines that appear in the video.
People watching movies or pictures, although the reality of the scene is to know the three-dimensional, but still assume that they are present in the screen or monitor the surface under the simple, that is, in the screen or monitor for the window of the huge space inside The
Two white lines to determine the surface, so covered in the white line of things on the "brain fill" beyond the surface, as if from the monitor inside drilled out.
Said so much, that "true 3D" no suspense is the 3D movie. Hollywood production of superhero large, with a 3D glasses, and Spiderman can be wandering over New York.
