Paraboloide hiperbòlic

Un paraboloide[1] és la superfície il·limitada formada pels punts que equidisten d'un punt fix anomenat focus i un pla anomenat director.

Aquesta és l'equació del paraboloide de distància p del focus al pla director, amb el pla director perpendicular a l'eix x i el focus a l'origen de coordenades:

y² + z² = 2 · p · x

Es pot entendre com format per la revolució d'una paràbola al voltant del seu eix.[2]
