This figure shows a finite portion of a hyperbolic paraboloid, and a twisted cubic curve that lies on the surface. The curve is shown in green. {Actually, the curve has been thickened slightly -- in the directions perpendicular to the surface at each point -- in order to make it more visible.}

I made the figure on this page by substituting my own data in a Geometry Center webpage.
