    public abstract class Drawable
extends Object
implements IGLRenderer, ISortableDraw
    A Drawable defines objects that may be rendered into an OpenGL context provided by a ICanvas. A Drawable must basically provide a rendering function called draw() that receives a reference to a GL2 and a GLU context. It may also use a reference to a Camera in order to implement specific behaviors according to the Camera position. A Drawable provides services for setting the transformation factor that is used inside the draw function, as well as a getter of the object's BoundingBox3d. Note that the BoundingBox must be set by a concrete descendant of a Drawable. A good practice is to define a setData function for initializing a Drawable and building its polygons. Since each class may have its own inputs, setData is not part of the interface but should be used as a convention. When not defining a setData function, a Drawable may have its data loaded by an add(Drawable) function. Note: A Drawable may last provide the information whether it is displayed or not, according to a rendering into the FeedBack buffer. This is currently supported specifically for the AxisBox object but could be extended with some few more algorithm for referencing all GL2 polygons.
