Abstract

A method for interpolating rows of data points with B-spline surfaces is presented. In each row the number points can differ, requiring a skinning-type operator to pass a surface through the points. To avoid data explosion as a result of knot merging, we introduce a new curve interpolation method that uses knots from a given input knot vector. Depending on the initial knot vector and how it is updated during interpolation from row to row, the new method reduces the number of surface control points by 60-97%.
