摘要
本文介绍URN模型在计算机辅助几何设计(CAGD)中的应用,提出两类新的概率模型——双次抽取模型与匹配抽取模型,给出递推公式,得到相应的调配函数.结果表明:设计新的URN模型,便可以得到新的调配函数.
This paper introduces some applications of the URN models to computer-aided design.Two kinds of probability model, double selection model and matched sampling model, are introduced, giving relevant recursion formulas and corresponding blending functions.The results show that new blending functions can be obtained from the designing of new URN models.
