Use the javax.media.j3d.J3DGraphics2D class to do this, as
documented at:

  
http://java.sun.com/products/java-media/3D/forDevelopers/J3D_1_2_API/j3dapi/index.html

Get it as:

  DisplayRendererJ3D dr = display.getDisplayRenderer();
  VisADCanvasJ3D canvas = dr.getCanvas();
  javax.media.j3d.J3DGraphics2D g2d = canvas.getGraphics2D();

You might want to search the java3d-interest mailing list
archive for information about J3DGraphics2D.

Good luck,
Bill
