Gaussian surface — A Gaussian surface is a closed two dimensional surface through which a flux or electric field is to be calculated. The surface is used in conjunction with Gauss s law (a consequence of the divergence theorem), allowing one to calculate the total… … Wikipedia
Gaussian blur — Gaussian blur, named for Carl Friedrich Gauss, describes blurring an image by a Gaussian function. It is a widely used effect in graphics software, typically to reduce image noise and reduce detail. The visual effect of this blurring technique is … Wikipedia
Gaussian curvature — In differential geometry, the Gaussian curvature or Gauss curvature of a point on a surface is the product of the principal curvatures, κ 1 and κ 2, of the given point. It is an intrinsic measure of curvature, i.e., its value depends only on how… … Wikipedia
Surface — This article discusses surfaces from the point of view of topology. For other uses, see Differential geometry of surfaces, algebraic surface, and Surface (disambiguation). An open surface with X , Y , and Z contours shown. In mathematics,… … Wikipedia
Gaussian gravitational constant — Carl Friedrich Gauss expressed the gravitational constant in units of the solar system rather than SI units. The benefit is that the motion of the planets can be accurately described, without exact knowledge of the scale of the solar system or… … Wikipedia
gaussian curvature — sēən noun or gauss curvature Usage: usually capitalized G Etymology: K. F. Gauss died 1855 + English ian : the reciprocal of the product of the two principal radii of curvature of a surface at any of its points … Useful english dictionary
Parametric surface — A parametric surface is a surface in the Euclidean space R3 which is defined by a parametric equation with two parameters. Parametric representation is the most general way to specify a surface. Surfaces that occur in two of the main theorems of… … Wikipedia
Developable surface — In mathematics, a developable surface is a surface with zero Gaussian curvature. That is, it is a surface that can be flattened onto a plane without distortion (i.e. stretching or compressing ). Conversely, it is a surface which can be made by… … Wikipedia
Saddle surface — A saddle surface is a smooth surface containing one or more saddle points. The term derives of the peculiar shape of historical horse saddles, which curve both up and down.Classical examples of two dimensional saddle surfaces in the Euclidean… … Wikipedia
Focal surface — For a surface in three dimension the focal surface, surface of centers or evolute is formed by taking the centers of the curvature spheres, which are the tangential spheres whose radii are the reciprocals of one of the principal curvatures at the … Wikipedia
Enneper surface — In mathematics, in the fields of differential geometry and algebraic geometry, the Enneper surface is a surface that can be described parametrically by:: x = u(1 u^2/3 + v^2)/3, : y = v(1 v^2/3 + u^2)/3, : z = (u^2 v^2)/3. It was introduced by… … Wikipedia
