generate method

@override List<Point> generate(List<Point> points)

Generates curve points from the given data points.

Implementation

@override
List<Point> generate(List<Point> points) {
  if (points.length < 2) return List.from(points);
  if (points.length == 2) return List.from(points);

  final n = points.length;
  final result = <Point>[];
  const segments = 10;

  // Calculate spline coefficients
  final px = _naturalSpline(points.map((p) => p.x).toList());
  final py = _naturalSpline(points.map((p) => p.y).toList());

  result.add(points.first);

  for (int i = 0; i < n - 1; i++) {
    for (int j = 1; j <= segments; j++) {
      final t = j / segments;
      final x = _evaluateSpline(px, i, t);
      final y = _evaluateSpline(py, i, t);
      result.add(Point(x, y));
    }
  }

  return result;
