parametric representation of a closed “Cylinder”












0














Assume I have a parametric curve $r(t) = <X(t),Y(t)>$ that defines a closed curve (like a circle or a closed B-spline) on a 2D plane.



The cylinder can be defined as:



$f(u,v) = <X(u), Y(u), v>$



For bounded values of $u$ and $v$.



This however gives us a sleeve (there's holes on the top and the bottom). If $r(t)$ is any arbitrary, paramateric, closed curve defined in 2D, how can you close the top?
