package PrsMgr
---Purpose: The PrsMgr package provides low level services
-- and is only to be used when you do not want to use
-- the services provided by AIS.
-- PrsMgr manages display through the following services:
-- - supplying a graphic structure for the object to be presented
-- - recalculating presentations when required, e.g. by
-- moving the object or changing its color
-- - defining the display mode of the object to be
-- presented; in the case of AIS_Shape, for example,
-- this determines whether the object is to be displayed in:
-- - wireframe 0
-- - shading 1.
-- Note that each new Interactive Object must have all its display modes defined.

enumeration TypeOfPresentation3d is TOP_AllView, TOP_ProjectorDependant
end TypeOfPresentation3d;
---Purpose: To declare the type of presentation as follows
-- - AllView for display involving no recalculation for
-- new projectors (points of view)in hidden line removal mode
-- - ProjectorDependant for display in hidden line
-- removal mode, where every new point of view
-- entails recalculation of the display.
