Code Examples

Example 1: Creating 2D Cubic Spline

Point2dCollection fitPoints = new Point2dCollection();
fitPoints.Add(new Point2d(0, 0));
fitPoints.Add(new Point2d(5, 5));
fitPoints.Add(new Point2d(10, 3));
fitPoints.Add(new Point2d(15, 7));

CubicSplineCurve2d spline = new CubicSplineCurve2d(fitPoints);

ed.WriteMessage($"\n2D cubic spline created");
