第一種算法的特點(diǎn)是重建結(jié)果不依賴于頂點(diǎn)的處理順序，不需要進(jìn)行控制頂點(diǎn)的初估及修正，可使各控制頂點(diǎn)的計(jì)算一次完成。 - Two methods are given to get the control vertexes , by making the two approximated helix segments gc2 continuous at their connecting point and leting the theoretical helix and the approximated one coincident at five points respectively

4 )研究了b樣條曲線光順的問(wèn)題，在傳統(tǒng)能量法的基礎(chǔ)上提出了b樣條曲線的一種光順?lè)椒?。該方法通過(guò)對(duì)局部控制頂點(diǎn)的修改來(lái)進(jìn)行曲線光順。 - It's difficult to find control vertex in a sentence. 用control vertex造句挺難的
- The general idea behind the second one is approximation . the control mesh is subdivided until the error between the control vertices and corresponding subdivision surface is less than a given threshold . then the vertices substitute those points on the surface approximately . the last step is to calculate offset point for every vertex and connect them to form an offset surface
第二種算法采用逼近思想，首先通過(guò)對(duì)控制網(wǎng)格進(jìn)行細(xì)分，當(dāng)控制頂點(diǎn)和細(xì)分曲面的距離滿足一定誤差要求時(shí)，近似用控制頂點(diǎn)代替細(xì)分曲面上的點(diǎn)，然后對(duì)各個(gè)頂點(diǎn)分別求等距點(diǎn)。 - It offers the idea according to problem faced , considering the good character of the ends , the ajusted cubic b - spline curve is used to fit ship lines . it finds out the control vertexs according to a sequence of given points , and then , through particular formula , each point in the curve could be worked out . it smoothes lines with the method based on small - paramter
針對(duì)面臨的問(wèn)題，提出了自己的思路，在數(shù)學(xué)計(jì)算方法上，由于三次準(zhǔn)均勻b樣條曲線良好的端部性質(zhì)，這里用它來(lái)擬合船舶型線，首先根據(jù)所給的初步型值求出其控制頂點(diǎn)，然后根據(jù)相關(guān)公式進(jìn)行插值便能得到曲線上的所有插值點(diǎn)。 - During the past decades , some researchers , such as : bezier , kj . versprile , deboor and cox , etc . had made great progress in the filed of constrained b - spline curve and surface fitting . in this article the method of constrained b - spline curve was introduced , which is used to figure out the control vertexes . using this interpolation method we can calculate every points of a uniform b - spline
并且分析了在各種端點(diǎn)情況下，在重節(jié)點(diǎn)的情況下，如何反算控制多邊形的頂點(diǎn)；如何在求出控制多邊形頂點(diǎn)之后，插值計(jì)算b樣條擬合曲線上的每一點(diǎn)；并通過(guò)結(jié)合雙尾船的型線，采用visualc + +和autocad2002為平臺(tái)，分別編制了相應(yīng)的軟件，對(duì)提供的型值做出繪圖處理，取得了良好的效果。
