point at infinity
名詞
point at infinity (複数形 points at infinity)
- An asymptotic point in 3-dimensional space, viewed from some point, at which parallel lines appear to meet and which in perspective drawing is represented as a vanishing point.
- (geometry, Euclidean projective 幾何学) Any point added to a space to achieve projective completion.
- 1960, Roger A. Johnson, Advanced Euclidean Geometry, Republished 2007, page 45,
- 1990, Shreeram Shankar Abhyankar, Algebraic Geometry for Scientists and Engineers, page 10:
- 1997, Susan Addington, Stuart Levy, Lost in the Fun House: An Application of Dynamic Projective Geometry, James King, Doris Schattschneider, Geometry Turned On: Dynamic Software in Learning, Teaching, and Research, page 159,
- To unify the treatment of concurrent and parallel lines, define a point at infinity for each family of parallel lines, and declare each point at infinity to lie on each of the parallel lines that define it. […] Now parallel lines meet at infinity, and vanishing points are the images of points at infinity.
- 2003, Ron Goldman, Pyramid Algorithms: A Dynamic Programming Approach to Curves and Surfaces for Geometric Modeling, page 18:
- (geometry, hyperbolic 幾何学) An ideal point.
- 1996, John Stillwell, Sources of Hyperbolic Geometry, page 82:
- 2007, Maurice Margenstern, Cellular Automata in Hyperbolic Spaces, Volume 1: Theory, page 66,
- As we have seen, points at infinity behave as ordinary points: a single line passes through two distinct points at infinity or through a point in the plane and a point at infinity.
- This representation of the points at infinity is a difference between the disc and the half-plane models of Poincaré, […] .
- 2012, Norbert A'Campo, Athanase Papadopoulos, Notes on non-Euclidean Geometry, Athanase Papadopoulos (editor), Strasbourg Master Class on Geometry, page 126,
- To describe a parabolic transformation f of the hyperbolic plane, we consider two parallel lines l and l’ and we call ω their common point at infinity.
使用する際の注意点
In Euclidean or affine spaces, depending on the dimensionality and nature of the space, the projective completion may comprise a single point at infinity (such as in the cases of the real projective line かつ the Riemann sphere) or a set called the line, plane or hyperplane at infinity.
In hyperbolic geometry, points at infinity (more commonly called ideal points) are not regarded as belonging to the space, but are bounding points, each line in the space having two distinct such points. The set of ideal points forms a quadric.

The CPU 14 of the automatic focusing system detects whether or not the system is in focus by displacing the wobbling lens WL of a photographing lens to the closest side and the infinity side, and acquiring and comparing a focal point evaluation value at each displacement point, or detects a focusing direction when the system is out of focus.例文帳に追加
オートフォーカスシステムのＣＰＵ１４は、撮影レンズのワブリングレンズＷＬを至近側と無限遠側に変位させて各変位点での焦点評価値を取得し比較することによって合焦しているか否か、又は，合焦していない場合の合焦方向を検出する。 - 特許庁
Upon focusing from infinity to a short-distance object point, the second lens group G2 moves along an optical axis to an image side, and at least a part of the third lens group G3 moves to have a component in a direction orthogonal to an optical axis.例文帳に追加
