Java3D : Painting 2D HUD over a Canvas3D

我正在使用Java3D渲染三维场景。我想在3d图像上方叠加一个二维的“平视显示器”。如何有效地在3d Canvas 顶部绘制2d内容？

谢谢!

最佳答案

    // 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);
        }
    };
