41class View from Visual3d inherits DataStructureManager from Graphic3d
42
43 ---Version:
44
45 ---Purpose: Creation and edition of a view in a 3D visualiser.
46 -- A 3D view is composed of an "orientation" part defined
47 -- by the position of the observer, the direction of view,
48 -- and a "mapping" part defined by the type of projection
49 -- (parallel or perspective) and by the window-viewport
50 -- couple which allows passage from the projected coordinate
51 -- space into the screen space.
52 -- Summary of 3D Viewing
53 -- To define a view, you must define:
54 -- - The view orientation transformation
55 -- - The view mapping transformation
56 -- - The view representation.
57 -- To activate a view, you must define:
58 -- - The associated window.
