parallax

n. the way an object seems to move when you look at it from a different place.

n. the apparent displacement of an observed object due to a change in the position of the observer.

“If you hold your finger in front of your face and close one eye, then the other, the finger's position changes because of parallax.”

“The photographer had to adjust for parallax error because the viewfinder was slightly offset from the camera's actual lens.”

Technical

n. a method used by astronomers to calculate the distance to stars by looking at them from different sides of the Earth's orbit.

n. the angle used to determine the distance of celestial bodies, specifically the semi-angle of the maximum parallax created by the Earth's orbit.

“Astronomers use stellar parallax to measure the distance of stars that are relatively close to our solar system.”

“By measuring the tiny shift in a star's position relative to distant galaxies over six months, researchers can calculate its distance via annual parallax.”

Technical

v. to move different parts of a digital image at different speeds to make it look 3D.

v. to produce an illusion of depth in computer graphics by moving background layers slower than foreground layers.

“The video game uses a parallax effect to make the mountains in the background look very far away.”

“The web designer implemented a parallax scrolling effect to create a more immersive and three-dimensional experience for mobile users.”
