ILNumerics 3D轮廓图传奇未显示原因?

我用来创建三维等高线图的表面轮廓。 我现在已经在我的3D图中绘制轮廓线,这也很有效,但传说中没有显示为什么?

代码:

private void button1_Click(object sender, EventArgs e)
{
    ILArray<float> data = ILSpecialData.sincf(50, 50);

    BackgroundWorker bgw = new BackgroundWorker();
    bgw.DoWork += bgwCreateProcess_DoWork;
    bgw.RunWorkerAsync(data);
}

private void bgwCreateProcess_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
    ILArray<float> data = e.Argument as ILArray<float>;

    using (ILScope.Enter())
    {
        ILScene scene = new ILScene();

        ILPlotCube plotCube = new ILPlotCube(twoDMode: false);

        plotCube.Rotation = Matrix4.Rotation(new Vector3(1, 0, 0), Math.PI / 2);

        ILSurface surface = new ILSurface(data);

        List<ContourLevel> conturLevels = new List<ContourLevel>();
        conturLevels.Add(new ContourLevel() { Text = "Limit Max", Value = 0.9f, LineWidth = 2 });
        conturLevels.Add(new ContourLevel() { Text = "Limit Min", Value = -0.1f, LineWidth = 2 });
        conturLevels.Add(new ContourLevel() { Text = "Average", Value = 0.5f, LineWidth = 3 });

        ILContourPlot contourPlot = new ILContourPlot(data, conturLevels, create3D: true);
        plotCube.Children.Add(contourPlot);

        ILLegend legend = new ILLegend();
        legend.Location = new PointF(.99f, 0f);
        surface.Children.Add(legend);

        ILColorbar colorbar = new ILColorbar();
        colorbar.Location = new PointF(.99f, 0.4f);
        surface.Children.Add(colorbar);

        surface.Markable = false;
        surface.Fill.Markable = false;
        surface.Wireframe.Markable = false;

        surface.Wireframe.Visible = true;

        surface.UseLighting = false;

        plotCube.Add(surface);

        scene.Add(plotCube);

        ilPanel.Scene = scene;
    }
}

此代码应扩展为winform,ILPanel和按钮。最后但必须订阅按钮的Click事件。更少的代码是不可能的,因为否则情况会发生变化。

Felix,代码中有几个问题。其中一些与ILNumerics中的错误有关,将在下一版本中修复。以下代码创建了一个类似的图像:

Contour Plot with Legend

private void button1_Click(object sender, EventArgs e) {
    ILArray<float> data = ILSpecialData.sincf(50, 50);

    BackgroundWorker bgw = new BackgroundWorker();
    bgw.DoWork += bgwCreateProcess_DoWork;
    bgw.RunWorkerAsync(data);
}

private void bgwCreateProcess_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e) {

    using (ILScope.Enter()) {
        ILArray<float> data = e.Argument as ILArray<float>;
        ILScene scene = new ILScene();

        ILPlotCube plotCube = new ILPlotCube(twoDMode: false);

        plotCube.Rotation = Matrix4.Rotation(new Vector3(1, 0, 0), Math.PI / 2);

        ILSurface surface = new ILSurface(data);

        List<ContourLevel> conturLevels = new List<ContourLevel>();
        conturLevels.Add(new ContourLevel() { Text = "Limit Max", Value = 0.9f, LineWidth = 2 });
        conturLevels.Add(new ContourLevel() { Text = "Limit Min", Value = -0.1f, LineWidth = 2 });
        conturLevels.Add(new ContourLevel() { Text = "Average", Value = 0.5f, LineWidth = 3 });

        ILContourPlot contourPlot = new ILContourPlot(data, conturLevels, create3D: true);
        plotCube.Add(contourPlot);

        ILLegend legend = new ILLegend("one","two","three","four");
        legend.Location = new PointF(.99f, 0f);


        ILColorbar colorbar = new ILColorbar();
        colorbar.Location = new PointF(.99f, 0.4f);
        surface.Add(colorbar);

        surface.Markable = false;
        surface.Fill.Markable = false;
        surface.Wireframe.Markable = false;

        surface.Wireframe.Visible = true;

        surface.UseLighting = false;

        plotCube.Add(surface);
        surface.Fill.Visible = false;

        scene.Add(plotCube);

        contourPlot.Add(legend);
        legend.Configure();  // only needed in version 3.2.2.0!
        scene.Configure();

        ilPanel1.Scene = scene;
    }
}

让我们逐步完成代码:

  1. 如您所见,我隐藏了表面填充颜色。否则,等高线图的标签可能会被表面隐藏。

  2. 传说应添加到他们将要描述的情节中。我将图例添加到等高线图而不是表面。但是,由于某些原因,图例不会自动从等高线图中找到轮廓线,所以......

  3. ...我在图例构造函数中手动添加了图例条目。在这里,我只使用了字符串“one”......“three”。您需要用自己的名字替换它。

  4. 由于我提到的错误,你必须明确地调用legend.Configure()。版本3.2.2.0之后将不再需要这样做。

  5. 您正在后台工作线程中进行场景修改 - 这很好!但是,完成配置后,必须发信号通知面板以刷新自身。但是,ilPanel.Refresh()需要从main(GUI-)线程调用。所以我怀疑,您可以在bgwCreateProcess_DoWork结束时使用Control.Invoke()来调用ilPanel.Refresh()。否则,将不会显示更改。
