3D:

Standard 3D technology is a type of 3D technology used in many theaters and home entertainment systems to create the illusion of three-dimensional depth in a movie or other video content. It uses a process called stereoscopy, in which two slightly offset images are displayed on the screen, one for each eye. The viewer wears 3D glasses with polarized lenses, which allow each eye to see only the image intended for it, creating the illusion of depth.

IMAX 3D:

IMAX 3D is a type of 3D technology used in IMAX theaters to enhance the 3D movie-watching experience. It is designed to provide a more immersive and lifelike 3D experience by using larger screens, higher frame rates, and higher quality 3D glasses.

4DX:

4DX is a type of 3D technology that adds environmental effects, such as movement and scents, to the movie-watching experience. It uses special chairs that move and vibrate in sync with the action on the screen, as well as various other effects, such as wind, mist, and scents, to create a more immersive experience.

Overall, IMAX 3D is designed to provide a more immersive and high-quality 3D experience compared to standard 3D technology, while 4DX adds additional environmental effects to the movie-watching experience.
