I. New features:
I.1 class BOPAlgo_Section
The class clontains the algorithm to build a result of Secton between the arguments.
The result of Section consists of vertices and edges.
The result of Section contains:
1. new vertices that are subjects of V/V, E/E, E/F, F/F interferences
2. vertices that are subjects of V/E, V/F interferences
3. new edges that are subjects of F/F interferences
4. edges that are Common Blocks
5.a vertex is included in result of Section only when it is not shared
between the edges of the result of Section
The class BOPAlgo_Section inherits the functionality of root class BOPAlgo_Builder
1.2 class BOPTest_Objects
method:
BOPAlgo_Section& BOPTest_Objects::Section()
has been added to get access to BOPAlgo_Section object
II. Changes:
II.1. class BOPAlgo_BOP
method:
void BOPAlgo_BOP::BuildSection()
has been removed
methods:
void BOPAlgo_BOP::CheckData()
void BOPAlgo_BOP::Prepare()
void BOPAlgo_BOP::PerformInternal1(const BOPAlgo_PaveFiller& theFiller)
const TopTools_ListOfShape& BOPAlgo_BOP::Generated
(const TopoDS_Shape& theS)
have been modified to eliminate references on Section operation
II.2. class BOPAlgo_PaveFiller
method:
void BOPAlgo_PaveFiller::UpdateFaceInfo
(BOPDS_DataMapOfPaveBlockListOfPaveBlock& theDME)
modified to prevent the usage of negative index in Data Structure
II.3. class BOPTest_Objects
static function:
Standard_Integer bopsection(Draw_Interpretor& di, Standard_Integer n, const char** a)
has been modified to use BOPAlgo_Section object instead of BOPAlgo_BOP object
static function:
Standard_Integer bbop(Draw_Interpretor& di,
Standard_Integer n,
const char** a)
has been modified to use BOPAlgo_Section object instea of BOPAlgo_BOP object
II.4. class BRepAlgoAPI_BooleanOperation
field:
myBuilder
the type has been changed from BOPAlgo_BOP* to BOPAlgo_Builder*
method:
void BRepAlgoAPI_BooleanOperation::Build()
has been modified to use BOPAlgo_Section object
II.5. class QANewModTopOpe_Tools
method:
Standard_Boolean QANewModTopOpe_Tools::HasSameDomain(
const BOPAlgo_PBOP& theBuilder,
const TopoDS_Shape& theFace)
void QANewModTopOpe_Tools::SameDomain(
const BOPAlgo_PBOP& theBuilder,
const TopoDS_Shape& theFace,
TopTools_ListOfShape& theResultList)
the type of the parameter <theBuilder> has been modified
to use BOPAlgo_Builder* instead of BOPAlgo_BOP*
II.6. The method:
const TopTools_ListOfShape& BOPAlgo_BOP::Generated
(const TopoDS_Shape& theS)
has been removed

deferred class BooleanOperation from BRepAlgoAPI
|
|
inherits MakeShape from BRepBuilderAPI
|
|
|
|
---Purpose: The abstract class BooleanOperation is the root
|
|
-- class of Boolean Operations (see Overview).
|
|
-- Boolean Operations algorithm is divided onto two parts.
|
|
-- - The first one is computing interference between arguments.
|
|
-- - The second one is building the result of operation.
|
|
-- The BooleanOperation class provides execution of both parts
|
|
-- of the Boolean Operations algorithm. The second part
|
|
-- (building the result) depends on given type of the Boolean
|
|
-- Operation (see Constructor).
