3D video refers to a type of visual media that creates the illusion of depth, making images appear more lifelike. This is achieved by presenting two slightly different images to each eye, mimicking how humans perceive depth in the real world. 3D videos can be experienced through special glasses or advanced display technologies. The technology behind 3D video is often used in movies, video games, and virtual reality experiences. Popular films like those from the Avatar franchise have showcased the immersive potential of 3D. As technology advances, 3D video continues to evolve, enhancing viewer engagement and realism.
