b-spline cubic curve 中文意思是什麼
b-spline cubic curve
解釋
樣條三次曲線-
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。 -
A fairing method based on energy me thod for cubic b - spline curves is presented. since only local control vertices ar e modified, this method, compared with energy method, not only makes the c omputation faster, but also makes the changes in shape of curve less
4 )研究了b樣條曲線光順的問題,在傳統能量法的基礎上提出了b樣條曲線的一種光順方法。該方法通過對局部控制頂點的修改來進行曲線光順。
