3D Film is a type of movie that uses special technology to create the illusion of depth in the image. The term '3D Film' is often used interchangeably with the term 'Deepie, ' which is a 6-letter word derived from the phrase 'deep perspective.' 3D films use stereoscopic techniques to create the illusion of depth, making the audience feel as if they are part of the action. This effect is achieved by using two cameras to capture two slightly different perspectives of the same scene, which are then combined to create the illusion of depth. 3D films have become increasingly popular in recent years, and are now used in a variety of genres, from horror to animation.
