In the cinema to buy 10 dollars of polarized 3D glasses in any movie theater to see the same?
Polarizer, is the driver wearing, the polarizer does not have 3D effect!
In fact, almost all lenses are the same, the difference is good bad frames.Good point of the frame with a comfortable point with a comfortable point
First of all, we can see that the light is polarized, the treated light has a polarization direction (the direction of the light itself is constant), but we still look the sameThen there is a kind of lens, called polarized lens, he also has the polarization direction, the same direction of polarization of light can pass, different light can not passWhen the 3D film was shot, it was shot with two cameras at different angles (almost separate from each other), and the two groups of images were projected onto the screen after processing in different polarization directionsIf you don't take 3D glasses, you look like you are two groups of fuzzy picture together. If put on the 3D glasses, because the polarizing lens filter, left and right eyes see a different picture, like we use glasses to see the real goods. According to the calculation of brain will produce three-dimensional feeling.Red and blue color filter is to produce 3D effect, the effect of low cost, look tired for a long time
