頂插條
英文
tip cutting-
It may be supposed, then, franz did not wait for a repetition of this permission, but took off the handkerchief, and found himself in the presence of a man from thirty - eight to forty years of age, dressed in a tunisian costume - that is to say, a red cap with a long blue silk tassel, a vest of black cloth embroidered with gold, pantaloons of deep red, large and full gaiters of the same color, embroidered with gold like the vest, and yellow slippers ; he had a splendid cashmere round his waist, and a small sharp and crooked cangiar was passed through his girdle
這當然是很容易想象得到的：弗蘭茲無須這種許可再說第二遍，就立刻解開了他的手帕，他發現自己已站在了一個年約三十八至四十歲的男子面前。那人穿著一套突尼西亞人的服裝，那是一頂紅色的便帽，帽上垂下一長綹藍色的絲穗，一件繡金邊的黑色長袍，深紅色的褲子，同色的扎腳套，扎腳套很寬大，也象長袍一樣是繡金邊的，一雙黃色的拖鞋他的腰部圍著一條華麗的絲帶，腰帶上插著一柄鋒利的小彎刀。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
並且分析了在各種端點情況下，在重節點的情況下，如何反算控制多邊形的頂點；如何在求出控制多邊形頂點之後，插值計算b樣條擬合曲線上的每一點；並通過結合雙尾船的型線，採用visualc + +和autocad2002為平臺，分別編制了相應的軟體，對提供的型值做出繪圖處理，取得了良好的效果。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
針對面臨的問題，提出了自己的思路，在數學計算方法上，由於三次準均勻b樣條曲線良好的端部性質，這里用它來擬合船舶型線，首先根據所給的初步型值求出其控制頂點，然後根據相關公式進行插值便能得到曲線上的所有插值點。In the process of degree reduction, two cases are considered respectively, one of which is about the case without conditions of endpoint interpolations, the other of which is about the case with conditions of endpoint interpolations of higher orders
兩種方法均考慮了不帶端點插值條件和具有端點高階插值條件的情形，並給出了降階said - ball曲線控制頂點的顯示表示式。分享友人
