A new method that can be used to analyze the developability of a curved surfaces " mesh is proposed based on gaussian theory of mapping a curved surface onto a unit global surface. 3. a new method is proposed to homo - topologically map a triangular finite element mesh into a planar shape based on the assumption that the surface deformation is continuous and homogeneous
3 、根據曲面變形連續均勻的特點，提出了一種基於單元等變形的三角形曲面網格拓撲等價映射演算法，將可展曲面與不可展曲面的網格採用統一的形式展開到平面上。 -
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，但卻缺乏局部控制性質。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。
