ベジェまたは多項式モデルの直接的な局所表現

概要

One of the most encountered problems in the data processing of curves and surfaces modeled by polynomial or Bezier representation is to find a new model for only a portion of the data that we want to manipulate without using the whole model. One solution is to manipulate the portion of curves or surfaces generated from the model directly.Another one is to generatea new model which redefines this portion of curves or surfaces.vvOur method,however,can generate a new model from the old one without manipulating the data of curves and surfaces.The new piecewise curves or surfaces have the same order as the original curves or surfaces respectively.This new method is not complocated because it is given as explicit expressions between control points and polynomial coefficients repectively.
