The 37 pages that link to Affine transformation, each with the reason it gives.
Function compositionBroader topic: Composing affine transformations combines geometric actions into one map.
Rotation matrixCompared with: Unlike general affine transformations, rotation matrices preserve Euclidean distances and angles.
Barycentric coordinatesRelated: Barycentric coordinates remain unchanged under affine transformations of the entire configuration.
Conversion of unitsRelated: Temperature-scale changes include an offset and therefore are not pure scaling.
Congruence (geometry)Compared with: Affine maps can stretch a figure, so they do not generally preserve congruence.
Point groupCompared with: General affine transformations need not preserve the metric structure of point-group symmetries.
Affine spaceRelated: Such maps preserve the structure defining an affine space.
Coordinate transformationBroader topic: It captures coordinate changes that include both rotation or scaling and an origin shift.
Affine geometryBroader topic: These transformations define which geometric properties affine geometry preserves.
Linear mapCompared with: A nonzero translation breaks preservation of vector addition, unlike a linear map.
Linear operatorCompared with: Translations generally break linearity by moving the zero vector.
Projective transformationCompared with: It is a more restrictive map: projective transformations need not preserve parallelism.
Vector graphicsRelated: Affine transforms move, rotate, and resize vector objects without changing their basic structure.
Möbius transformationBroader topic: When c=0, a Möbius transformation reduces to an affine map.
Cross-ratioCompared with: Affine maps preserve more structure than projective maps, but the cross-ratio remains invariant under both.
Similarity (geometry)Compared with: Unlike similarity transformations, general affine transformations need not preserve shape.
Affine combinationRelated: Preservation of these combinations characterizes affine maps.
Change of variablesCompared with: Affine substitutions shift or rescale coordinates without the curvature of nonlinear maps.
Euclidean planeRelated: It describes many plane transformations used in graphics and geometry.
ParallelogramRelated: Affine maps send parallelograms to parallelograms, even when lengths and angles change.
Similarity transformationNarrower topic: Every similarity is affine, while general affine maps can distort shape.
Point (geometry)Related: It moves points while preserving affine relations such as collinearity.
Sierpiński triangleRelated: Each recursive step uses scaled and translated copies of the original triangle.
Inverse elementRelated: Invertible affine maps can be undone by their inverse transformations.
Linear functionRelated: In one dimension, such transformations have the form x ↦ mx + b.
Rigid motionCompared with: It preserves less geometric structure than a rigid motion.
Affine subspaceRelated: Affine transformations send affine subspaces to affine subspaces.
Inversive geometryCompared with: Affine maps preserve lines and parallelism; inversion generally bends lines into circles.
Mazur–Ulam theoremBroader topic: The theorem concludes that every surjective isometry has this form.
Von Neumann–Morgenstern utility theoremRelated: Positive affine changes preserve expected-utility rankings and explain the representation’s uniqueness.
D'Arcy Wentworth ThompsonRelated: Thompson’s transformation grids show how such mappings can relate animal forms.
2D computer graphicsRelated: It provides the standard operations for positioning and reshaping 2D graphics.
Dittert conjectureRelated: Affine changes of coordinates relate simplex shapes while changing volume by a determinant factor.
Geometry (configuration)Related: It describes stretching, shearing, and other changes that preserve affine structure.
Monsky's theoremRelated: Affine changes of coordinates preserve the equal-area condition up to a common factor.
Pohlke's theoremRelated: Parallel projection is affine, which explains why spatial frames can yield planar segment triples.
Ryll-Nardzewski fixed-point theoremNarrower topic: The theorem requires every map in the semigroup to preserve convex structure.
