如果不从ARX编程中来看这个问题,很难回答。
在ARX中创建样条曲线对象,需要这样的两个参数:
order :The order of the spline to be created (in the range 2 to 26)
fitTolerance :The tolerance to which the spline should approximate fitPoints
帮助系统中的解释是这样的:
Creates a spline that attempts to fit an order degree curve to the array of points within the tolerance fitTolerance. A fitTolerance of 0 causes the curve to be interpolated precisely through all the points in the points array. The curve order may be in the range 2 to 26.
