Alternative definition of the noun affine transformation

noun

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

Explanation

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.
