Hey Rita.

Do you just want to turn a poly-type into something representing a parameterization of the poly-type in the given embedded space?

As an example if you have say a 3D cube example, you pick say a parameterization of (u,v) and then have a parameterization (that will not be smooth but it will be continuous) to describe x(u,v), y(u,v), z(u,v) for u in [0,1] and v in [0,1].
