使用LINQ分配Vector3D数组

        List<Vector3D> vectors = new List<Vector3D>()

        };

        Vector3D[] filteredVectors = vectors
            .Where(v => v.X > 5) // 筛选X大于5的向量
            .ToArray();

        foreach (var vector in filteredVectors)
        {
            Console.WriteLine($"X: {vector.X}, Y: {vector.Y}, Z: {vector.Z}");

    public Vector3D(double x, double y, double z)
