A roof having the shape of a geometric figure called a hyperbolic paraboloid.
The roof structure consists of cranked trusses formed from straight tubular members each truss set at a different angle to create the compound curve.
In this position the hyperbolic paraboloid opens downward along the x axis and upward along the y axis that is the parabola in the plane x 0 opens upward and the parabola in.

The exhibition hall is 135m long and enclosed by two hyperbolic paraboloid roofs rising to a central ridge 29m high.
Although the hyperbolic paraboloid is curved in two directions it is composed entirely of straight lines.
The entire roof structure rests on only two supports giving it an appearance somewhat resembling a bird in flight.
A hyperbolic paraboloid sometimes referred to as h p is a doubly curved surface that resembles the shape of a saddle that is it has a convex form along one axis and a concave form on along the other.
It is also a doubly ruled surface that is every point on its surface lies on two straight lines across the surface.
A hyperbolic paraboloid not to be confused with a hyperboloid is a doubly ruled surface shaped like a saddle in a suitable coordinate system a hyperbolic paraboloid can be represented by the equation.
