3D projection.

We all love to see 3D movies because 3D movies give us a more realistic experience than 2D and mostly we like to see action movies in 3D.

Now we first know about 3D.

What is 3D?

‌We make graphs and charts in the school with the X-axis being horizontal, and the Y-axis being vertical, these things are very much the same in the world of 3D, with one more addition – there's a third axis: Z, which represents depth.

So by definition, any object that can be represented on a three-axis system is 3D. 

3D may seem generally in action movies and other casual entertainment,
The 3D projectors are generally similar to 2D projectors, they require both some additional parts as well as specially formatted content.

3D Projector

Like any normal projector, a 3D projection unit has a bulb, an image engine, and a lens. 3D projectors use image engines that can update quickly because some have to show twice as many images to make up a single 3D field. They also add either an infrared emitter or a small radio transmitter that sends a signal to the 3D glasses to keep them in sync with the projected images.

3D Glasses

To see the 3D image(content), every viewer needs to wear special active shutter 3D glasses. These glasses have lenses that can be darkened separately for both eyes for small fractions of seconds.
when the projector shows the image for the left eye, its emitter sends a command to the glasses to darken the right eye and vice-versa for the right-eye images. This ensures that viewers see the left-eye image with their left eye and the right-eye image with their right eye. Their brains then assemble the separate images into a single 3D image.
But this technique is not used in all types of 3D projection instead simple polarization glass is used in normal 3D to see the 3D image(content).

That is all about 3D in this article we have understood about 3D,3D projectors, and 3D glasses.
