Now there are 3D movie downloads on the Internet, but the blue and red glasses bought on the market do not have the 3D effect. Would you please go back to the cinema and get their 3D glasses back? Can I use it? Or is there a signal in the theater? It's useless when you take it awayThe trouble with us.Yes, of course. I went to the flying room yesterday. There is something similar to the infrared in the glasses. You can't see the 3D image with the slight obstruction of your hand. Also, please don't COPY information, answer questions, detail and real points.
Without watching that particular movie, there would be no 3D effect.
If we wear 3D glasses, because of the polarizing lenses, we can see the different pictures from the left and right eyes, the same as when we see the real things with glasses. According to the calculation of the brain will produce three-dimensional feeling.Other movie theaters are large screen speakers, there is no signal problemThat's not a signal.. Signals and light are two entirely different things. If it's a signal, you can't see it and your hands can't stop it.
The answer is yes. First of all, let me talk about the principle of 3D glasses3D glasses need to be compatible with 3D movies. It's no use watching ordinary movies.First of all, the light can be polarized, the treated light has a polarization direction (the direction of the light itself is constant), but we still look like the original light.Then there is a lens, called a polarizing lens, which also has a polarization direction, and the light in the same direction of polarization can pass through, and different light can not pass.When filming in 3D, in different angles (almost double the separate angle) placed two cameras shooting together, when it was released two pictures with different polarization direction after processing, then projected onto the screen.If you don't wear 3D glasses at this time, you look like two sets of pictures blurred together.
