splines:方便高效的B样条

花键 方便高效的B样条曲线。 该软件包可让您生成相当有效的代码，以使用评估任意程度的B样条。 例子 构造和评估二阶B样条： var splines = require ( "splines" ) var bspline = splines . bspline ( 2 ) ; var vals = [ ] for ( var i = - 3 * 6 ; i <= 3 * 6 ; i ++ ) { vals . push ( bspline ( i / 6 ) ) ; } console . log ( vals ) 输出 [0,0,0,0,0,0,0,0,0,0,0.013888888888888902,0.05555555555555553,0.125,0.2222222222222222, 0.34722222222222227,0.5,0.638888888888889,
