-- File: AIS_Shape.cdl
-- Created: Fri Dec 20 15:18:05 1996
-- Author: Robert COUBLANC
-- <rob@robox.paris1.matra-dtv.fr>
-- GG : GER61351 17/11/1999 Change SetColor() with a compatible Quantity_Color instead
-- the restricted NameOfColor.
-- Redefines the Color(),Material(),Transparency() methods
-- for taking in acount the current facing model.
-- GG : BUC60536 The compute methods must be defined "protected"
-- and no more "private"
---Copyright: Matra Datavision 1996
class Shape from AIS inherits InteractiveObject from AIS
---Purpose: A framework to manage presentation and selection of shapes.
-- AIS_Shape is the interactive object which is used the
-- most by applications. There are standard functions
-- available which allow you to prepare selection
-- operations on the constituent elements of shapes -
-- vertices, edges, faces etc - in an open local context.
-- The selection modes specific to "Shape" type objects
-- are referred to as Standard Activation Mode. These
-- modes are only taken into account in open local
-- context and only act on Interactive Objects which
-- have redefined the virtual method
-- AcceptShapeDecomposition so that it returns true.
-- Several advanced functions are also available. These
-- include functions to manage deviation angle and
-- deviation coefficient - both HLR and non-HLR - of
-- an inheriting shape class. These services allow you to
-- select one type of shape interactive object for higher
-- precision drawing. When you do this, the
-- AIS_Drawer::IsOwn... functions corresponding to the
-- above deviation angle and coefficient functions return
-- true indicating that there is a local setting available
-- for the specific object.
