However, the stretching and shearing transformations warp shapes, as the following example shows: This is an example of image warping. However, the affine transformations do not facilitate projection onto a curved surface or radial distortions. See more In Euclidean geometry, an affine transformation or affinity (from the Latin, affinis, "connected with") is a geometric transformation that preserves lines and parallelism, but not necessarily Euclidean distances See more Let X be an affine space over a field k, and V be its associated vector space. An affine transformation is a bijection f from X onto itself that is an See more As shown above, an affine map is the composition of two functions: a translation and a linear map. Ordinary vector algebra uses matrix multiplication to represent linear maps, and See more An affine map $${\displaystyle f\colon {\mathcal {A}}\to {\mathcal {B}}}$$ between two affine spaces is a map on the points that acts linearly on the vectors (that is, the vectors between points of the space). In symbols, $${\displaystyle f}$$ determines a linear transformation See more By the definition of an affine space, V acts on X, so that, for every pair (x, v) in X × V there is associated a point y in X. We can denote this action … See more Properties preserved An affine transformation preserves: 1. collinearity between points: three or more points which lie on … See more The word "affine" as a mathematical term is defined in connection with tangents to curves in Euler's 1748 Introductio in analysin infinitorum.
