我使用的Java3D渲染三维场景。我想上的三维图像的顶部覆盖的二维抬头显示器。我怎样才能有效地绘制2D内容的3D画布之上？

谢谢！

  //使用preferred配置创建一个Canvas3D
    Canvas3D canvas3d =新Canvas3D（配置）
    {
        私有静态最后长的serialVersionUID = 7144426579917281131L;

        公共无效postRender（）
        {
            。this.getGraphics2D（）setColor（Color.white）;
            。this.getGraphics2D（）束带（抬头显示器（HUD）作品！，100,100）;
            this.getGraphics2D（）平齐（假）。
        }
    };
 

I'm using Java3D to render a three-dimensional scene. I would like to overlay a two-dimensional "heads-up-display" on top of the 3d image. How can I efficiently paint the 2d content on top of the 3d canvas?

Thanks!

    // Create a Canvas3D using the preferred configuration
    Canvas3D canvas3d = new Canvas3D(config)
    {
        private static final long serialVersionUID = 7144426579917281131L;

        public void postRender()
        {
            this.getGraphics2D().setColor(Color.white);
            this.getGraphics2D().drawString("Heads Up Display (HUD) Works!",100,100);
            this.getGraphics2D().flush(false);
        }
    };
