jzy3d builder无法解决eclipse上的错误

Question

所以，我最近（通过 Maven）下载了 jzy3d 库，这样我就可以将我现有的程序从 JS 转换和改进为 Java，并且为了掌握新库，我正在尝试一些可用的示例library site 但是，正如标题所示，我不断收到“无法解析生成器”错误。 我尝试添加 org.jzy3d.plot3d.builder.Builder 导入但也没有成功，因为它返回未使用的导入警报。

这是我的代码：

package randomProjects;

import org.jzy3d.chart.Chart;
import org.jzy3d.chart.ChartLauncher;
import org.jzy3d.colors.Color;
import org.jzy3d.colors.ColorMapper;
import org.jzy3d.colors.colormaps.ColorMapRainbow;
import org.jzy3d.maths.Range;
import org.jzy3d.plot3d.builder.Mapper;
import org.jzy3d.plot3d.builder.concrete.OrthonormalGrid;
import org.jzy3d.plot3d.primitives.Shape;
import org.jzy3d.plot3d.rendering.canvas.Quality;

public class SurfPlotTest_JZY3D {

    public static void main(String[] args){
        
        // Define a function to plot
        Mapper mapper = new Mapper() {
            public double f(double x, double y) {
                return 10 * Math.sin(x / 10) * Math.cos(y / 20) * x;
            }
        };

        // Define range and precision for the function to plot
        Range range = new Range(-150, 150);
        int steps = 50;

        // Create a surface drawing that function;
        Shape surface = Builder.buildOrthonormal(new OrthonormalGrid(range, steps, range, steps), mapper);
        surface.setColorMapper(new ColorMapper(new ColorMapRainbow(), surface.getBounds().getZmin(), surface.getBounds().getZmax(), new Color(1, 1, 1, .5f)));
        surface.setFaceDisplayed(true);
        surface.setWireframeDisplayed(false);
        surface.setWireframeColor(Color.BLACK);

        // Create a chart and add the surface
        Chart chart = new Chart(Quality.Advanced);
        chart.getScene().getGraph().add(surface);
        ChartLauncher.openChart(chart);
        
    }
    
}

这是错误信息：

Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
    Builder cannot be resolved
    The field Quality.Advanced is not visible

    at randomProjects.SurfPlotTest_JZY3D.main(SurfPlotTest_JZY3D.java:30)

我还发现在第 37 行的程序中还有另一个错误很重要，我尝试通过 Quality.Advanced() 修复交换 Quality.Advanced em>，但又一次，没有任何成功。

稍作更新，希望得到答案

如果我使用手动导入的项目文件，也可以在库站点中找到，我不会收到生成器错误，而是在编译时返回以下错误。

The project: org.jzy3d-0.9 which is referenced by the classpath, does not exist.

这是项目中的示例代码

package org.jzy3d.demos.surface;

import org.jzy3d.chart.Chart;
import org.jzy3d.chart.controllers.keyboard.camera.CameraKeyController;
import org.jzy3d.colors.Color;
import org.jzy3d.colors.ColorMapper;
import org.jzy3d.colors.colormaps.ColorMapRainbow;
import org.jzy3d.demos.AbstractDemo;
import org.jzy3d.demos.DemoLauncher;
import org.jzy3d.maths.Range;
import org.jzy3d.plot3d.builder.Builder;
import org.jzy3d.plot3d.builder.Mapper;
import org.jzy3d.plot3d.builder.concrete.OrthonormalGrid;
import org.jzy3d.plot3d.primitives.Shape;
import org.jzy3d.plot3d.rendering.canvas.Quality;

public class ColorWaveDemo extends AbstractDemo {
    public static void main(String[] args) throws Exception {
        DemoLauncher.openDemo(new ColorWaveDemo());
    }

    public ColorWaveDemo() {
    }

    @Override
    public void init() {
        // Define a function to plot
        Mapper mapper = new Mapper() {
            public double f(double x, double y) {
                return x * Math.sin(x * y);
            }
        };

        // Define range and precision for the function to plot
        Range range = new Range(-3, 3);
        int steps = 80;

        // Create the object to represent the function over the given range.
        final Shape surface = Builder.buildOrthonormal(new OrthonormalGrid(range, steps, range, steps), mapper);
        surface.setColorMapper(new ColorMapper(new ColorMapRainbow(), surface.getBounds().getZmin(), surface.getBounds().getZmax(), new Color(1, 1, 1, .5f)));
        surface.setFaceDisplayed(true);
        surface.setWireframeDisplayed(false);

        // Create a chart
        chart = new Chart(Quality.Advanced, getCanvasType());
        chart.getScene().getGraph().add(surface);
        chart.addController(new CameraKeyController());
    }
}

认为我是一个通过 Maven 或其他方式导入库的完全菜鸟，我这样做是为了掌握并学习如何操作，所以我希望能得到详细的回答。如果需要，我还可以包含我的 .pom 文件。

网站上的教程页面已经过时了。您可能会发现tutorials that are embedded in the library 更容易使用，例如this surface example.

readme of this module 也应该有所帮助。
