  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

    5 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. 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.

  7. Ellipsoid: Definition, Equation & Volume Explained Simply

    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.
