Definition of the noun affine transformation

What does affine transformation mean as a name of something?


  1. (mathematics) a transformation that is a combination of single transformations such as translation or rotation or reflection on an axis
    • domain: math / mathematics / maths
    • lexical domain: Relations - nouns denoting relations between people or things or ideas
    • more generic word: transformation = a function that changes the position or direction of the axes of a coordinate system

Alternative definition of the noun affine transformation


  1. [geometry, linear algebra] a linear transformation between vector spaces followed by a translation.


Affine transformation: In geometry, an affine transformation, affine map or an affinity is a function between affine spaces which preserves points, straight lines and planes. Also, sets of parallel lines remain parallel after an affine transformation. An affine transformation does not necessarily preserve angles between lines or distances between points, though it does preserve ratios of distances between points lying on a straight line.
