Class ISceneGraphEventsBeforeDrawEvent

  extended by java.util.EventObject
      extended by com.esri.arcgis.analyst3d.ISceneGraphEventsBeforeDrawEvent
All Implemented Interfaces:

public class ISceneGraphEventsBeforeDrawEvent
extends EventObject


This event method is often used by an OpenGL routine that renders something before the main features in the scene are drawn. A good example is the scene background, such as sky/sun/moon etc. Just like the art of painting, one normally needs to draw the background first and then the main feature. So this method is generally for the background rendering. It can also be used for executing some routines other than drawing.

The BeforeDraw method returns a boolean value. When it's set to true, the SceneGraph's drawing is disabled, and you as a developer take control of the drawing (e.g. via OpenGL). Otherwise, the SceneGraph takes care of drawing as usual.
