pick
Determines the WorldWind shapes displayed in a screen rectangle. The screen rectangle is interpreted as coordinates in Swing screen pixels relative to this view.
If the screen rectangle intersects any number of WorldWind shapes, the returned list contains a picked object identifying all the top shapes in the rectangle. This picked object includes the shape renderable (or its non-null pick delegate) and the WorldWind layer that displayed the shape. Shapes that are entirely hidden behind another shape or terrain in the screen rectangle are omitted from the returned list.
