67deferred class View from V3d
68
69 ---Purpose: Defines the application object VIEW for the
70 -- VIEWER application.
71 -- The methods of this class allow the editing
72 -- and inquiring the parameters linked to the view.
73 -- (Projection,Mapping,Zclipping,DepthCueing,AntiAliasing
74 -- et Conversions) .
75 -- Warning: The default parameters are defined by the class
76 -- Viewer (Example : SetDefaultViewSize()).
77 -- Certain methods are mouse oriented, and it is
78 -- necessary to know the difference between the start and
79 -- the continuation of this gesture in putting the method
80 -- into operation.
81 -- Example : Shifting the eye-view along the screen axes.
82 --
83 -- View->Move(10.,20.,0.,True) (Starting motion)
84 -- View->Move(15.,-5.,0.,False) (Next motion)
