Curves
One-dimensional curves from algebra, differential geometry and topology.
Classic curves as well as new examples and counter-examples. Immersed curves
and curves on surfaces. A parametrized curve c in a euclidean 3-space is a map
c : [a, b] -> R3
from an interval [a, b] of the real line into R3, which may have
self-intersections or be knotted.
The curves in this model server are often specified as
a polygon immersed in a euclidean space Rn.

As a guide, polygons should be connected, no degenerate edges, no duplicate vertices.
