ellipsoid
[ noun ]
a surface whose plane sections are all ellipses or circles
<noun.shape> the Earth is an ellipsoid [ adj ]
having the nature or shape of an ellipsoid
<adj.all>
Ellipsoid \El*lip"soid\, n. [Ellipse + -oid: cf. F. ellipsoide.] (Geom.) A solid, all plane sections of which are ellipses or circles. See {Conoid}, n., 2 (a) .
Note: The ellipsoid has three principal plane sections, a, b, and c, each at right angles to the other two, and each dividing the solid into two equal and symmetrical parts. The lines of meeting of these principal sections are the axes, or principal diameters of the ellipsoid. The point where the three planes meet is the center.
{Ellipsoid of revolution}, a spheroid; a solid figure generated by the revolution of an ellipse about one of its axes. It is called a prolate spheroid, or prolatum, when the ellipse is revolved about the major axis, and an oblate spheroid, or oblatum, when it is revolved about the minor axis.
Ellipsoid \El*lip"soid\, Ellipsoidal \El`lip*soi"dal\, a. Pertaining to, or shaped like, an ellipsoid; as, ellipsoid or ellipsoidal form.
Conoid \Co"noid\ (k[=o]"noid), n. [Gr. kwnoeidh`s conical; kw^nos cone + e'i^dos form: cf. F. cono["i]de.] 1. Anything that has a form resembling that of a cone.
2. (Geom.) (a) A solid formed by the revolution of a conic section about its axis; as, a parabolic conoid, elliptic conoid, etc.; -- more commonly called {paraboloid}, {ellipsoid}, etc. (b) A surface which may be generated by a straight line moving in such a manner as always to meet a given straight line and a given curve, and continue parallel to a given plane. --Math.
