问题
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);
}
};
