package Dynamic
|
|
|
|
---Purpose: This package propose a set of abstract persistent
|
|
-- classes. These classes may be sort in three main
|
|
-- groups, which are :
|
|
--
|
|
-- - fuzzy classes
|
|
-- - methods
|
|
-- - dynamic classes
|
|
--
|
|
-- And in two complementary groups used by the
|
|
-- previously described family, which are :
|
|
--
|
|
-- - parameter classes
|
|
-- - variable classes
|
|
--
|
|
-- All the main classes are manipulated through two
|
|
-- steps which are :
|
|
--
|
|
-- - the definition which gives the signature of the
|
|
-- object
|
|
-- - the instanciation which always references a
|
|
-- definition
|
|
--
|
|
-- This separation has been created to clearly
|
|
-- separate the definition of an object, a method or
|
|
-- a class which is the description and the instance
|
|
-- which is the utilisation with a particular set of
|
|
-- values. In this case for few instanciations of
|
|
-- the same object, the definition can be unique.
|
|
--
|
|
-- Each family address a particular problem.
|
|
--
|
|
-- Dynamic class
|
|
-- -------------
|
|
--
|
|
-- This family of classes offers the possibility to
|
|
-- define and to manipulate dynamically objets with
|
|
-- the same specifications as C++ objects.
|
|
-- Dynamically means without CDL description and
|
|
-- without compilation and link if all the methods
|
|
-- attached are interpreted methods.
|
|
--
|
|
-- The first thing to do is to define the signature
|
|
-- of the class, in terms of fields and methods.
|
|
--
|
|
-- You can also derive a class from others, add
|
|
-- fields, and add or redefine methods.
|
|
--
|
|
-- Then instances of the class can be created and
|
|
-- values can be assigned to the fields.
|
|
--
|
|
-- It is then possible to execute methods attached to
|
|
-- the definition of the class. These methods may set
|
|
-- computed values to other fields, or simply return
|
|
-- them.
|
|
--
|
|
-- A method can be compiled or interpreted.
|
|
--
|
|
-- Fuzzy class
|
|
-- -----------
|
|
--
|
|
-- A fuzzy class is a degeneration of a dynamic
|
|
-- class. Only the fields are specified. These
|
|
-- classes are useful to describe objects with
|
|
-- various definitions, and with the number and the
|
|
-- nature of fields depending of the definition.
|
|
--
|
|
-- The definitions of the lights for Photo Realistic
|
|
-- Renderer is an illutration of the use of the fuzzy
|
|
-- classes.
|
|
--
|
|
-- These lights have the same definitions in terms of
|
|
-- parameters as the lights used in the LightWorks
|
|
-- module.
|
|
--
|
|
-- For each type of light an exhaustive set of
|
|
-- parameters is described, and each parameter is
|
|
-- defined by its name, its type and, if necessary,
|
|
-- its default value as follows :
|
|
--
|
|
-- ambient
|
|
-- "intensity" Standard_Real 1.0
|
|
-- "colour" Materials_PColor 1.0 1.0 1.0
|
|
--
|
|
-- distant
|
|
-- "intensity" Standard_Real 1.0
|
|
-- "colour" Materials_PColor 1.0 1.0 1.0
|
|
-- "location" PGeom_CartesianPoint 0.0 0.0 1.0
|
|
-- "to" PGeom_CartesianPoint 0.0 0.0 0.0
|
|
-- "shadows" Standard_Boolean Standard_False
|
|
-- "shadow resolution" Standard_Integer 256
|
|
-- "shadow quality" Standard_Integer 4
|
|
-- "shadow softness" Standard_Real 1.0
|
|
--
|
|
-- eye
|
|
-- "intensity" Standard_Real 1.0
|
|
-- "colour" Materials_PColor 1.0 1.0 1.0
|
|
--
|
|
-- point
|
|
-- "intensity" Standard_Real 1.0
|
|
-- "colour" Materials_PColor 1.0 1.0 1.0
|
|
-- "location" PGeom_CartesianPoint 0.0 0.0 0.0
|
|
-- "fall off" LightWorks_LiFallOffType LI_FALL_OFF_CONSTANT
|
|
-- "shadows" Standard_Boolean Standard_False
|
|
-- "shadow resolution" Standard_Integer 256
|
|
-- "shadow quality" Standard_Integer 4
|
|
-- "shadow softness" Standard_Real 1.0
|
|
--
|
|
-- spot
|
|
-- "intensity" Standard_Real 1.0
|
|
-- "colour" Materials_PColor 1.0 1.0 1.0
|
|
-- "location" PGeom_CartesianPoint 0.0 0.0 1.0
|
|
-- "to" PGeom_CartesianPoint 0.0 0.0 0.0
|
|
-- "fall off" LightWorks_LiFallOffType LI_FALL_OFF_CONSTANT
|
|
-- "cone angle" Standard_Real 60.0
|
|
-- "cone delta angle" Standard_Real 5.0
|
|
-- "beam distribution" Standard_Real 2.0
|
|
-- "shadows" Standard_Boolean Standard_False
|
|
-- "shadow resolution" Standard_Integer 256
|
|
-- "shadow quality" Standard_Integer 4
|
|
-- "shadow softness" Standard_Real 1.0
|
|
--
|
|
-- All these definitions are described in a file
|
|
-- which is read at the first creation of a light
|
|
-- instance to be put in a dictionary.
|
|
--
|
|
-- At the creation of an instance, just a reference
|
|
-- on the definition is set. All the parameter values
|
|
-- are read in the definition. If now a value of one
|
|
-- parameter is changed, the modified parameter is
|
|
-- added to the instance. So only the modified
|
|
-- parameters are directely attached to the instance.
|
|
-- This behaviour allows the use of an instance as
|
|
-- definition, and can be useful to create catalogs
|
|
-- of standards which can be directly questioned in
|
|
-- the database.
|
|
--
|
|
-- The use of fuzzy classes needs four prerequisites
|
|
-- which are :
|
|
--
|
|
-- - The creation of a file with the exhaustive
|
|
-- description of all the possible types taken by an
|
|
-- object and for each type the complete set of
|
|
-- parameters in terms of name, type, and, if
|
|
-- necessary, default value.
|
|
--
|
|
-- - The inheritance from the class
|
|
-- FuzzyDefinitionsDictionary and, if necessary, the
|
|
-- redefinition of the Switch method for the non-
|
|
-- standard type of parameters described in the file.
|
|
--
|
|
-- - The following method :
|
|
--
|
|
-- void DictionaryOfDefinitions(Handle(MyPackage_MyDictionary)&);
|
|
--
|
|
-- must be writen in the file MyPackage.cxx, because
|
|
-- this method is automatically called by the
|
|
-- constructor of FuzzyInstance. This method tests if
|
|
-- the dictionary has been created yet. If it is
|
|
-- true the method returns a reference to it,
|
|
-- otherwise the method creates the dictionary before
|
|
-- returning the reference.
|
|
--
|
|
-- - The instanciation of the FuzzyInstance class
|
|
-- with the pre-defined dictionary.
|
|
--
|
|
-- Method class
|
|
-- ------------
|
|
--
|
|
-- The behaviour of these classes are similar to
|
|
-- fuzzy classes. Only the semantic is different.
|
|
-- These classes are for memorized actions or
|
|
-- constraints, e.g. they are useful to memorized
|
|
-- persistently the working system of Imagine
|
|
-- Conception.
