1. 3D film. A 3D or 3-D (three-dimensional) film or S3D (stereoscopic 3D) film [5] is a motion picture that enhances the depth cues seen by the viewer. The most common approach to the production of 3D films is derived from stereoscopic photography.
Depth sensation is the corresponding term for non-human animals, since although it is known that they can sense the distance of an object, it is not known whether they perceive it in the same way that humans do. [1] Depth perception arises from a variety of depth cues. These are typically classified into binocular cues and monocular cues ...
The Necker Cube: a wire frame cube with no depth cues. Figures drawn in a way that avoids depth cues may become ambiguous. Classic examples of this phenomenon are the Necker cube, [6] and the rhombille tiling (viewed as an isometric drawing of cubes). To go further than just perceiving the object is to recognize the object.
[1] Some languages, for example, many East Asian languages, such as Chinese varieties (e.g. Mandarin, Cantonese, Min, and Wu), and partially Korean and Japanese, are written in logographic scripts; single glyphs represent whole morphemes. [2] Examples of logographic cues include traffic signs, restroom signs, and pictorial flashcards.
A cue is some organization of the data present in the signal which allows for meaningful extrapolation. For example, sensory cues include visual cues, auditory cues, haptic cues, olfactory cues and environmental cues. Sensory cues are a fundamental part of theories of perception, especially theories of appearance (how things look).
Stereoscopy creates the impression of three-dimensional depth from a pair of two-dimensional images. [5] Human vision, including the perception of depth, is a complex process, which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make sense of the raw information.
Under normal circumstances, the depth specified by stereopsis agrees with other depth cues, such as motion parallax (when an observer moves while looking at one point in a scene, the fixation point, points nearer and farther than the fixation point appear to move against or with the movement, respectively, at velocities proportional to the ...
A random-dot stereogram (RDS) is stereo pair of images of random dots that, when viewed with the aid of a stereoscope, or with the eyes focused on a point in front of or behind the images, produces a sensation of depth due to stereopsis, with objects appearing to be in front of or behind the display level.
