helix spline 中文意思是什麼
helix spline
解釋
螺旋線樣條線-
Bezier, b - spline, and their rational models play an important role in cad / cam systems. but these models show obvious shortcomings, such as no encompassing transcendent ( i. e., nonalgebraic ) curves, e. g. the circle, the cycloid, the catenary and the hyperbolic helix
B zier , b -樣條以及它們的有理模型在cad cam系統中有著非常重要的地位,但是這些模型也有著明顯的缺陷,譬如不能精確表示很多非代數曲線,如圓弧,擺線,懸鏈線,雙曲螺線等 -
And then we introduce bezier, b - spline and non - polynomial curves and surfaces modeling, which include l - splines, helix splines, splines in tension and c - curves etc. by analyzing the characters of bezier curves and b - spline curves, we construct trigonometric polynomial curves in the space of trigonometric functions, which assume the characters of b zier curves and b - spline curves
闡述了cagd中參數曲線曲面造型的發展歷史並介紹了bzier方法、 b樣條方法以及非多項式曲線曲面造型方法,後者包括l -樣條、螺旋樣條、張力樣條以及c -曲線等。文章以b zier曲線和b樣條曲線的特點為基礎,在三角函數空間中構造一組具有上述兩類曲線特性的三角函數多項式曲線,稱其為t - b zier曲線和t - b樣條曲線。
