Answer 1

create your own class extending Canvas3D.
This is one I wrote for 2D text be displayed over 3d canvas. should work with images.
import javax.swing.*;
import java.awt.*;
import com.sun.j3d.utils.universe.*;
import com.sun.j3d.utils.geometry.*;
import javax.media.j3d.*;
import javax.vecmath.*;
import com.sun.j3d.utils.image.*;
import javax.media.j3d.LineAttributes;
public class JoCanvas extends Canvas3D
     private String t;
     private Font f;
     public JoCanvas(GraphicsConfiguration gcIn)
          super(gcIn);
          f = new Font("Arial",0,30);
          t=" ";
     public void postRender()
          J3DGraphics2D g = getGraphics2D();
          g.setFont(f);
          g.setColor(Color.orange);
          g.drawString(t, 100, 100);
          g.flush(true);
     public void setText(String s)
          t=s;
          repaint();
}
