Class WPVSScene

java.lang.Object
  org.deegree.ogcwebservices.wpvs.j3d.WPVSScene

public class WPVSScene
extends Object

This class represents the basic class for creation of a 3D perspective views as specified in the OGC Web Perpective View Service specification. A WPVS scene is defined by a scene model and a date determining the light conditions. Additional elements are 3D or 2.5D-features that are placed into the scene, atmospheric conditions influencing the light and visibility (e.g. fog, rain etc., but currently not implemented) and additional light placed into the scene (e.g. street lights, spots, lighted windows etc.).
