Translation (geometry) - Wikipedia
https://en.wikipedia.org/wiki/Translation_(geometry)If is a fixed vector, known as the translation vector, and is the initial position of some object, then the translation function will work as . If is a translation, then the image of a subset under the function is the translate of by . The translate of by is often written . In geometry, a vertical translation (also known as vertical shift) is a translation o…
