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 slopes
  final tangents = _calculateTangents(points);

  result.add(points.first);

  for (int i = 0; i < n - 1; i++) {
    final p1 = points[i];
    final p2 = points[i + 1];
    final m1 = tangents[i];
    final m2 = tangents[i + 1];
    final dx = p2.x - p1.x;

    for (int j = 1; j <= segments; j++) {
      final t = j / segments;
      final point = _hermitePoint(p1, p2, m1 * dx, m2 * dx, t);
      result.add(point);
    }
  }

  return result;
