  1. Based on a systematic discussion on the contents, characteristics and the up - to - now accomplishments of these three operations in cagd, we present our researches in three ways as follows : ( 1 ) efficient evaluation for parametric curves and surfaces based on generalized ball bases based on the generalization of mathematical model of surface lofting program in the consurf system, two generalized ball surfaces and the recursive algorithms for evaluating them are given. furthermore, the conversion algorithms from bezier form of a surface to these two generalized ball forms are presented

    在系統地論述cagd中此三類運算的內容、特點、已有研究成果的基礎上,就以下三方面給出了研究成果: ( 1 )基於廣義ball基的參數曲線曲面快速求值以前英國航空公司consurf系統機身模線程序數學模型的推廣為基礎,定義了兩類廣義ball基曲面,給出了求值的遞推演算法,推導了b zier曲面到這兩類曲面的轉換演算法
