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 < 4) return [];

  final result = <Point>[];
  const segments = 10;

  for (int i = 1; i < points.length - 2; i++) {
    final p0 = points[i - 1];
    final p1 = points[i];
    final p2 = points[i + 1];
    final p3 = points[i + 2];

    for (int j = 0; j <= segments; j++) {
      final t = j / segments;
      final point = _basisPoint(p0, p1, p2, p3, t);
      result.add(point);
    }
  }

  return result;
