1. In addition , we often encounter a general problem - it is very difficult to describe a complex shape with a single bezier curve precise . method of bezier definites shape of curve , which is global project . if you locally modify curve , it is necessary to affact the global . it is that method of bezier has character of global control , but it has not charater of local control . by way of arbitrary partition . arbitrary degree elevation , that may increases control point . increases potential active character of controling curve . therefore , the thesis discusses mainly the problem of local free - form deformation , which may make bezier curve deform continuely and gain wanted figures . however , no matter what free - form deformation based on extension factor for parametric curve or arbitrary partition will reduce smoothness of parametric curve
   另外，我們經(jīng)常會遇到一個普遍問題，就是難以用單一的貝齊爾曲線段描述復(fù)雜的形狀。貝齊爾方法對形狀的定義是整體方案，欲對其作局部修改，必然會影響到整體，即貝齊爾方法是有整體控制性質(zhì)，但卻缺乏局部控制性質(zhì)。通過任意分割和任意升階得出所要變形的一段，以及增加控制點，增加對曲線進行控制的潛在靈活性。
2. It's difficult to find extension factor in a sentence. 用extension factor造句挺難的
