They not only inherit the advantages of bezier curves and b - spline curves, also can be used to represent straight lines precisely and some remarkable transcendental curves precisely, such as circular arc, ellipse, cardioids and twisted pair line etc. especially, the uniform t - b - spline curve of three degrees is smoother than b - spline curve and c - b - spline curve of the same order
此外由於它們還具有三角函數的優點,故既可以精確表示直線段、二次多項式曲線段又可以精確表示圓弧、橢圓弧等二次曲線以及心臟線、雙紐線等超越曲線。特別地, 3次均勻t - b樣條曲線曲面比同階均勻b樣條( c - b樣條)曲線曲面具有更高的光滑度。Based on b - spine function, the original contour line was smoothed and fitted. this method was successfully used to monitor the solid concentration in gas - solid fluidized bed
基於三次均勻b樣條函數對初始等灰度曲線進行曲線擬合,得到了光滑的等灰度曲線。
