pkv 8591531065 0025354: Intersection operation
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

Open CASCADE Technology
=======================

This directory contains sources of Open CASCADE Technology (OCCT), a software
development platform providing services for 3D surface and solid modeling, CAD 
data exchange, and visualization. Most of OCCT functionality is available in 
the form of C++ libraries. OCCT can be best applied in development of software 
dealing with 3D modeling (CAD), manufacturing / measuring (CAM) or numerical 
simulation (CAE).

License

Open CASCADE Technology is free software; you can redistribute it and / or 
modify it under the terms of the GNU Lesser General Public version 2.1 as 
published by the Free Software Foundation, with special exception defined in 
the file OCCT_LGPL_EXCEPTION.txt. Consult the file LICENSE_LGPL_21.txt included
in OCCT distribution for complete text of the license.

Alternatively, Open CASCADE Technology may be used under the terms of Open 
CASCADE commercial license or contractual agreement.

WARRANTY OF ANY KIND. The entire risk related to any use of the OCCT code and 
materials is on you. See the license text for formal disclaimer.

Packaging
---------

You can receive certified version of OCCT code in different packages.

- Snapshot of Git repository: contains only bare sources of OCCT; many C++ 
  files, HTML documentation, and project files / makefiles for building OCCT
  need to be generated.

- Complete source archive: contains all sources of OCCT, including C++ files
  generated by WOK, HTML and PDF documentation, and projects / makefiles for 
  building on all officially supported platforms.

- Binary package (platform-specific): in addition to complete source archive, 
  it includes binaries of OCCT and third-party libraries built on one platform. 
  This package allows using OCCT immediately after installation.

Certified versions of OCCT can be downloaded from http://www.opencascade.org

You can also find OCCT pre-installed on your system, or install it from 
packages provided by a third party. Note that packaging and functionality
of such versions can be different from certified releases. Please consult 
documentation accompanyog your version for details.

Documentation
-------------

Open file doc/html/index.html to browse HTML documentation.

If HTML documentation is not available in your package, you can:

- Generate it from sources. 

  You need to have Tcl and Doxygen 1.8.4 (or above) installed on your system.
  and accessible in your environment (check environment variable PATH).
  Run batch file *gendoc.bat* on Windows or Bash scriot *gendoc.sh* on Linux
  or Mac OS X to (re)generate documentation.

- Read documentation in source plain text (MarkDown) format found in 
  subfolder *dox*

See *dox/dev_guides/documentation/documentation.md* for details.

Building
--------

In most cases you need to rebuild OCCT on your platform (OS, compiler) before
using it in your project, to ensure binary compatibility.

Consult the file *dox/dev_guides/building/building.md* for instructions on
building OCCT from sources on supported platforms.

Version
-------

The current version of OCCT can be consulted in the file
*src/Standard/Standard_Version.hxx*

-----------
