佩林噪音不起作用； 返回奇怪的数字

Question

我刚开始我的第一个Perlin噪声项目，但是当我测试它时，它返回了惊人的高数字。
据我了解，它们应该保持在1到-1之间。

同样，当我将盲法更改为偶数时，它只会返回零。

应该注意的是，我使用Libnoise库的c＃端口。

这是我编写的代码：

namespace Perlin
{
    public partial class Form1 : Form
    {
        double frequency, lacunarity, persistence;
        int octaveCount, resolutie;

        public Form1()
        {
            InitializeComponent();
            LibNoise.Perlin perlinMap = new LibNoise.Perlin();
            // perlinMap.Frequency =
        }



        private void trackBar1_Scroll(object sender, EventArgs e)
        {
            octaveCount = trackBar1.Value;
            textBox1.Text = octaveCount.ToString();
            //  textBox5.Text = LibNoise.GradientNoiseBasis((double)trackBar1.Value,   (double)trackBar1.Value, (double)trackBar1.Value, 1024,     LibNoise.NoiseQuality.Standard).ToString;
        }

        private void textBox1_TextChanged(object sender, EventArgs e)
        {

        }

        private void trackBar2_Scroll(object sender, EventArgs e)
        {
            persistence = (trackBar2.Value * 5);
            textBox3.Text = persistence.ToString() + "%";
        }

        private void button1_Click(object sender, EventArgs e)
        {
            LibNoise.Perlin perlinMap = new LibNoise.Perlin();
            perlinMap.Lacunarity = lacunarity;
            perlinMap.NoiseQuality = LibNoise.NoiseQuality.Standard;
            perlinMap.OctaveCount = octaveCount;
            perlinMap.Persistence = persistence;
            perlinMap.Seed = 1024;

            textBox12.Text = perlinMap.GetValue(0.23, 0, 1).ToString();
            textBox13.Text = perlinMap.GetValue(1, 1.25, 1).ToString();
            textBox14.Text = perlinMap.GetValue(2, 0, 1.75).ToString();

            textBox15.Text = perlinMap.GetValue(0, 1, 1).ToString();
            textBox16.Text = perlinMap.GetValue(1, 1, 1).ToString();
            textBox17.Text = perlinMap.GetValue(2, 1, 1).ToString();

            textBox18.Text = perlinMap.GetValue(0, 2, 1).ToString();
            textBox19.Text = perlinMap.GetValue(1, 2, 1).ToString();
            textBox20.Text = perlinMap.GetValue(2, 2, 1).ToString();



        }

        private void trackBar3_Scroll(object sender, EventArgs e)
        {
            lacunarity = (trackBar3.Value / 2d + 0.5d);
            textBox7.Text = lacunarity.ToString();
        }

        private void trackBar4_Scroll(object sender, EventArgs e)
        {
            frequency = Math.Pow(2, trackBar4.Value + 1);
            textBox8.Text = frequency.ToString();
        }

        private void trackBar5_Scroll(object sender, EventArgs e)
        {
            frequency = Math.Pow(2, trackBar5.Value + 4);
            textBox10.Text = frequency.ToString();
        }
    }
}

任何帮助是极大的赞赏！

我发现很讨厌，持久性应该是0到1之间的值，而不是5到50之间的值。
