JavaFX 3D - 是否可以更改 DrawMode.Line 中线的宽度?

JavaFX 3D - Is it possible to change the width of Line in DrawMode.Line?

我想用 DrawMode.LINE 更改任何网格的 linewidth,但不知道可不可以

我添加了一些代码以供参考。

@Override
public void start(Stage primaryStage) throws Exception{
    PerspectiveCamera camera= new PerspectiveCamera(true);
    Group root = new Group();
    Scene scene = new Scene(root, 1024, 768, true);

    primaryStage.setScene(scene);
    primaryStage.show();

    scene.setFill(Color.BLACK);
    camera.setFarClip(10000);
    camera.setTranslateZ(-10);
    scene.setCamera(camera);

    Box box  = new Box();
    box.setDrawMode(DrawMode.LINE);
    root.getChildren().addAll(camera,box);
}


public static void main(String[] args) {
    launch(args);
}

这是不可能的。 DrawMode 被传递给默认线框为宽度为 1 的线的原生渲染器。对于 Direct3D 管道,请参阅 Outline and Fill State. Even if you use the line drawing support library 它会告诉您:

The library uses native hardware line drawing support (if available in the device) only if:

  • Line width is 1.
  • No line pattern is enabled.

不能用line primitives绘制不同于1的线宽,而必须用三角形来绘制:

The line drawing library emulates lines using texture triangles

换句话说,宽度1是特殊的,因为它有特定的硬件支持。
