Hyperboloid

A hyperboloid is a quadric, a type of surface in three dimensions.


Basic Description

A hyperboloid is a quadric surface in 3 dimensions that is generated by rotating a hyperbolic function around an axis.

The hyperbolic function  sin{hx} produces the graph on the left, and by rotating it about the y-axis we get a hyperboloids of one sheet.

They are represented by the following equations. {x^2 \over a^2} + {y^2 \over a^2} - {z^2 \over c^2}=1 \,  hyperboloid of one sheet,

or

- {x^2 \over a^2} - {y^2 \over a^2} + {z^2 \over c^2}=1 \,  hyperboloid of two sheets.

These curves can also be defined using the following parametric equations:

x(u,v)=a(\sqrt{1+u^2})cos{v}\,

y(u,v)=a(\sqrt{1+u^2})sin{v}\,

z(u,v)=cu\,
