package ShapeExtend
|
|
|
|
---Purpose: This package provides general tools and data structures common
|
|
-- for other packages in SHAPEWORKS and extending CAS.CADE
|
|
-- structures.
|
|
-- The following items are provided by this package:
|
|
-- - enumeration Status used for coding status flags in methods
|
|
-- inside the SHAPEWORKS
|
|
-- - enumeration Parametrisation used for setting global parametrisation
|
|
-- on the composite surface
|
|
-- - class CompositeSurface representing a composite surface
|
|
-- made of a grid of surface patches
|
|
-- - class WireData representing a wire in the form of ordered
|
|
-- list of edges
|
|
-- - class MsgRegistrator for attaching messages to the objects
|
|
-- - tools for exploring the shapes
|
|
-- - tools for creating new shapes.

enumeration Status is
|
|
---Purpose: This enumeration is used in
|
|
-- ShapeHealing toolkit for representing flags in the
|
|
-- return statuses of class methods.
|
|
-- The status is a field of the class which is set by one or
|
|
-- several methods of that class.
|
|
-- It is used for reporting about errors and other situations
|
|
-- encountered during execution of the method.
|
|
-- There are defined 8 values for DONE and 8 for FAIL flags:
|
|
-- ShapeExtend_DONE1 ... ShapeExtend_DONE8,
|
|
-- ShapeExtend_FAIL1 ... ShapeExtend_FAIL8
|
|
-- and also enumerations for representing combinations of flags:
|
|
-- ShapeExtend_OK - no flags at all,
|
|
-- ShapeExtend_DONE - any of flags DONEi,
|
|
-- ShapeExtend_FAIL - any of flags FAILi.
|
|
-- The class that uses statuses provides a method(s) which
|
|
-- answers whether the flag corresponding to a given
|
|
-- enumerative value is (are) set:
|
|
-- Standard_Boolean Status(const ShapeExtend_Status test);
|
|
-- Note that status can have several flags set simultaneously.
|
|
-- Status(ShapeExtend_OK) gives True when no flags are set.
|
|
OK, -- Nothing done, everything OK
|
|
DONE1, -- Something was done, case 1
|
|
DONE2, -- Something was done, case 2
|
|
DONE3, -- Something was done, case 3
|
|
DONE4, -- Something was done, case 4
|
|
DONE5, -- Something was done, case 5
|
|
DONE6, -- Something was done, case 6
|
|
DONE7, -- Something was done, case 7
|
|
DONE8, -- Something was done, case 8
|
|
DONE, -- Something was done (any of DONE#)
|
|
FAIL1, -- The method failed, case 1
|
|
FAIL2, -- The method failed, case 2
|
|
FAIL3, -- The method failed, case 3
|
|
FAIL4, -- The method failed, case 4
|
|
FAIL5, -- The method failed, case 5
|
|
FAIL6, -- The method failed, case 6
|
|
FAIL7, -- The method failed, case 7
|
|
FAIL8, -- The method failed, case 8
|
|
FAIL -- The mathod failed (any of FAIL# occured)

enumeration Parametrisation is
|
|
---Purpose: Defines kind of global parametrisation on the composite surface
|
|
Natural, -- each patch of the 1st row and column adds its range, Ui+1 = Ui + URange(i,1), etc.
|
|
Uniform, -- each patch gives range 1.: Ui = i-1, Vj = j-1
|
|
Unitary -- uniform parametrisation with global range [0,1]
|
|
end Parametrisation;
