paraboloid

• Surface dont les sections par des plans parallèles à un axe de coordonnées sont des paraboles, et dont les sections par des plans perpendiculaires à cet axe sont des ellipses (ou des hyperboles selon le signe des coefficients).

A surface that has parabolic cross-sections parallel to one coordinate axis and elliptical cross-sections perpendicular to that axis.
