Jzy3d 3d插值图不渲染

Question

我正在尝试绘制给定一组坐标的 3d 路径。从 jzy3d 的演示应用程序中，我发现这可以通过他们的 BernsteinInterpolator 和 LineStripInterpolated 类.

借助他们的源代码，我尝试重现如下：

public static void main(String[] args) {

    BernsteinInterpolator interp = new BernsteinInterpolator();

    List<Coord3d> controlCoords = new ArrayList<>();
    controlCoords.add(new Coord3d(0.0, 0.0, 0.0));        
    controlCoords.add(new Coord3d(1.0, 0.0, 1.0));
    controlCoords.add(new Coord3d(1.0, 0.0, 2.0));
    controlCoords.add(new Coord3d(1.0, 1.0, 2.0));
    controlCoords.add(new Coord3d(0.0, 1.0, 2.0));
    controlCoords.add(new Coord3d(3.0, 2.0, -1.0));

    LineStripInterpolated line = new LineStripInterpolated(interp, controlCoords, 30);

    Chart chart = new AWTChart(Quality.Intermediate);
    chart.add(line);
    chart.open("chart test", 600, 600);
}

根据演示应用程序，这是我希望得到的 -> DemoPlot

不幸的是，上面只呈现空白 window，没有错误或异常。有谁知道出了什么问题？非常感谢您的帮助！

所以我深入研究了源代码，发现有一种方法可以绕过 LineStripInterpolated class 如下：

public static void main(String[] args) {

    List<Coord3d> controlCoords = new ArrayList<>();
    controlCoords.add(new Coord3d(0.0F, 0.0F, 0.0F));
    controlCoords.add(new Coord3d(1.0F, 0.0F, 1.0F));
    controlCoords.add(new Coord3d(1.0F, 0.0F, 2.0F));
    controlCoords.add(new Coord3d(1.0F, 1.0F, 2.0F));
    controlCoords.add(new Coord3d(0.0F, 1.0F, 2.0F));
    controlCoords.add(new Coord3d(3.0F, 2.0F, -1.0F));

    BernsteinInterpolator interp = new BernsteinInterpolator();
    List<Coord3d> interpolatedCoords = interp.interpolate(controlCoords, 30);

    List<Point> controlPoints = new ArrayList<>();
    for (Coord3d coord : controlCoords) {
        controlPoints.add(new Point(coord, Color.RED, 5.0));
    }

    List<Point> interpPoints = new ArrayList<>();
    for (Coord3d coord : interpolatedCoords) {
        interpPoints.add(new Point(coord, Color.BLUE, 3.0));
    }

    LineStrip line = new LineStrip(interpolatedCoords);
    line.setWireframeColor(Color.BLACK);

    Chart chart = new AWTChart(Quality.Intermediate);
    chart.add(line);
    chart.add(controlPoints);
    chart.add(interpPoints);
    chart.open("chart test", 600, 600);
}

希望这对遇到同样问题的其他人有所帮助。我仍然很好奇为什么我以前的方法不起作用。 :(
