Generalized Cone
A Ruled Surface is called a generalized cone if it can be parameterized by 
, where
is a fixed point which can be regarded as the vertex of the cone. A generalized cone is a Regular Surfacewherever 
. The above surface is a generalized cylinder over a Cardioid.A generalized cone is a Flat Surface.
