Java3D：在Canvas3D上繪製2D HUD

Question

我使用Java3D渲染三維場景。我想在三維圖像上疊加一個二維「擡頭顯示器」。我怎樣纔能有效地繪製2D畫布上的2D內容？

謝謝！

// 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); 
     } 
    };
