popular culture have a profound impact on the formation of such mental images:The development of synthetic acoustic technologies and the creation of sound art have led to a consideration of the possibilities of a sound-image made up of irreducible phonic substance beyond linguistic or musicological analysis. Still or moving A is a single static image. This phrase is used in photography, visual media and the computer industry to emphasize that one is not talking about movies, or in very precise or pedantic technical writing such as a standard. A is typically a movie (film) or video, including digital video. It could also be an animated display such as a zoetrope. A still frame is a still image derived from one frame of a moving one. In contrast, a film still is a photograph taken on the set of a movie or television program during production, used for promotional purposes. Two-dimensional (2D) A two-dimensional (2D) image is a visual representation of something that is represented using only two spatial dimensions. Many 2D images are in the shape of rectangles. A common process by which 2D images have historically been displayed is called rasterization. , 2D images are the most common types of image. In image processing, a picture function is a mathematical representation of a two-dimensional image as a function of two spatial variables. The function f(x,y) describes the intensity of the point at coordinates (x,y). Three-dimensional (3D) Three-dimensional (3D) images are less common than two-dimensional images. Three-dimensional images feed into the visual system's perception of depth to more accurately portray visual information. Common physical forms of 3D images include holograms. Literature In literature, imagery is a "mental picture" which appeals to the senses. It can both be figurative and literal.
