Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight and is measured by the angle or half-angle of inclination between those two lines. [ 1][ 2] Due to foreshortening, nearby objects show a larger parallax than farther objects, so parallax can be used to determine distances.
Parallax scrolling is a technique in computer graphics where background images move past the camera more slowly than foreground images, creating an illusion of depth in a 2D scene of distance. [1] The technique grew out of the multiplane camera technique used in traditional animation [ 2 ] since the 1930s.
Stellar parallax is the apparent shift of position ( parallax) of any nearby star (or other object) against the background of distant stars. By extension, it is a method for determining the distance to the star through trigonometry, the stellar parallax method. Created by the different orbital positions of Earth, the extremely small observed ...
Parallax in astronomy. Stellar parallax motion from annual parallax. Half the apex angle is the parallax angle. Parallax is an angle subtended by a line on a point. In the upper diagram, the Earth in its orbit sweeps the parallax angle subtended on the Sun. The lower diagram shows an equal angle swept by the Sun in a geostatic model.

A “bartender’s handshake” is a drink order that signals to your bartender a few things: 1. You’re (likely) not a jerk, and 2. You might also be a bartender, or 3. You’re about to become ...
A parallax barrier is a device placed in front of an image source, such as a liquid crystal display, to allow it to show a stereoscopic or multiscopic image without the need for the viewer to wear 3D glasses. Placed in front of the normal LCD, it consists of an opaque layer with a series of precisely spaced slits, allowing each eye to see a ...
