  1. Ellipsoid - Wikipedia

    An ellipsoid is a surface that can be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation. An ellipsoid is a quadric surface; that is, a …

  2. Ellipsoid -- from Wolfram MathWorld

    2 days ago · The general ellipsoid, also called a triaxial ellipsoid, is a quadratic surface which is given in Cartesian coordinates by (x^2)/ (a^2)+ (y^2)/ (b^2)+ (z^2)/ (c^2)=1, (1) where the semi-axes are of …

  3. Ellipsoid - Math.net

    An ellipsoid has three axes of rotational symmetry. If an ellipsoid is rotated 180° (half a turn) about its axes, it will look the same as the original shape. The three axes are perpendicular to each other and …

  4. Ellipsoid | Surfaces, Axes, Foci | Britannica

    Ellipsoid, closed surface of which all plane cross sections are either ellipses or circles. An ellipsoid is symmetrical about three mutually perpendicular axes that intersect at the centre.

  5. Ellipsoid: A Simple Explanation - Andrea Minini

    An ellipsoid is a three-dimensional geometric shape that can be visualized as a stretched or flattened version of a sphere. In other words, it's a smooth, closed surface similar to a sphere but with different …

  6. Ellipsoid: Definition, Equation & Volume Explained Simply - Vedantu

    An ellipsoid is a three-dimensional surface that is a 3D analogue of an ellipse. It can be visualized as a sphere that has been stretched or compressed along its three perpendicular axes.

  7. The ellipsoid - Math Insight

    Just as an ellipse is a generalization of a circle, an ellipsoid is a generalization of a sphere. In fact, our planet Earth is not a true sphere; it's an ellipsoid, because it's a little wider than it is tall.

  8. 14. Ellipsoids | The Nature of Geographic Information

    An ellipsoid is a three-dimensional geometric figure that resembles a sphere, but whose equatorial axis (a in Figure 2.15.1, above) is slightly longer than its polar axis (b).

  9. Flexi answers - <p>What is an ellipsoid?</p> | CK-12 Foundation

    An ellipsoid is a three-dimensional geometric shape that resembles a stretched or compressed sphere. It is a type of quadric surface, which means it is defined by a second-degree equation in three variables.

  10. Ellipsoid Definition (Illustrated Mathematics Dictionary)

    Illustrated definition of Ellipsoid: A three-dimensional shape like a squashed sphere. All plane cross-sections are ellipses.
