Hyperbolic Paraboloid -- from Wolfram MathWorld
WEBMay 30, 2024 · A hyperbolic paraboloid is the quadratic and doubly ruled surface given by the Cartesian equation z= (y^2)/ (b^2)- (x^2)/ (a^2) (1) (left figure). An alternative form is z=xy (2) (right figure; Fischer 1986), which has parametric equations x (u,v) = u (3) y (u,v) = v (4) z (u,v) = uv (5) (Gray 1997, pp. 297-298).

Paraboloid - Wikipedia
WEBA hyperbolic paraboloid is a saddle surface, as its Gauss curvature is negative at every point. Therefore, although it is a ruled surface, it is not developable. From the point of view of projective geometry, a hyperbolic paraboloid is one-sheet hyperboloid that is tangent to the plane at infinity.

WEBHyperbolic Paraboloid. The hyperbolic paraboloid carries two families of straight lines. One may express this as: the surface is a “doubly ruled” surface. This animation starts with an almost flat example and stretches the z-ccordinate. - Note that each tangent plane intersects the surface in the two straight lines through the point of contact.
