1. A method for creating an optically smooth geometric model, comprising:
forming a loop from a plurality of parametrically defined curves;
creating a plurality of ribbons along each of the plurality of parametrically defined curves of the loop, each ribbon between a preceding parametrically defined curve of the loop and a subsequent parametrically defined curve of the loop; and
blending the ribbons to form a multi-sided surface patch between the parametrically defined curves, wherein a portion of each ribbon is Gkgeometric continuous with a portion of another ribbon of the plurality of ribbons, wherein k is dependent upon one or more criteria for optical smoothness of the geometric model.
