If the parametric equation gives you only a location than you can use this
location to make other objects like blob, sphere_sweep, union of other objects.
If the parametric equation gives you also direction vector without much
calculations and then it can give you set of circles along path then you could
consider making parametric surface as parametric{} object or as mesh{} from
