java.lang.Objectgov.nasa.worldwind.render.FrameFactory
public class FrameFactory
Static class for drawing 2D frames.
All shapes are drawn inside a bounding rectangle whose lower left corner is at the origin. Shapes with a leader use an offset point that indicate where the leader triangle should point at - it usually has a negative y since the leader connects at the bottom of the frame (at y = 0).
