elipsoidní
An elipsoidní (Czech for "ellipsoidal") shape refers to a three-dimensional geometric surface that is an ellipsoid, a smooth, closed surface resembling a squashed or stretched sphere. Ellipsoids are a generalization of spheres, where the three principal axes may have different lengths, resulting in varying degrees of flattening or elongation. This shape is fundamental in mathematics, physics, and engineering due to its ability to approximate complex surfaces with simpler models.
In mathematics, an ellipsoid is defined as the set of points in three-dimensional space where the sum
(x²/a²) + (y²/b²) + (z²/c²) = 1,
where *a*, *b*, and *c* are the semi-axes lengths along the x, y, and z axes, respectively.
Ellipsoids are widely used in geodesy and cartography to model the Earth's shape, which is not a
Ellipsoidal coordinates are a coordinate system adapted to the ellipsoid’s geometry, useful in solving partial differential
