1. Bug fix in reading old persistent data using FSD_File storage driver
2. Persistence compatible with legacy format was restored for shapes
a. Implemented a storage read / write wrapper for legacy persistence
b. Added DRAW commands to read / write files in legacy format
c. Added test cases for reading / writing operations with checking number of sub-shapes and physical properties
d. Updated related sections of the development guide
- New method BRepLib::FindValidRange() has been added. It computes the range of the edge not covered by boundary vertices.
- The algorithm of calculation of valid intersection range in the class IntTools_ShrunkRange has been corrected to use the new method.
- The method BOPTools_AlgoTools::MakeSplitEdge() has been improved to protect against errors in the case of reversed orientation of the input edge.
- Two new Draw commands have been added:
validrange - it calls the new method BRepLib::FindValidRange().
tolsphere - it shows tolerances of vertices by drawing a sphere around each vertex of the shape.
- The test cases "offset shape_type_i_c YE1,YE2" became better. The scripts have been corrected to reflect the new state.
1) BRepLib::UpdateTolerances(..) & BRepLib::SameParameter(..) functions now support non-mutable input feature. reshaper is used to store modified copies of subshapes of original (input) shape(s) as substitutions.
2) IsNewShape(..) method has been added to BRepTools_ReShape to check if the given shape has been recorded as a value
The Face/Face intersection procedure has been changed in Boolean Operations algorithm.
Previously, the intersection tolerance for all section curves between pair of faces has been calculated
as the maximal tolerance among all curves. Now, each curve has its own valid tolerance calculated
as the maximal deviation of the 3D curve from its 2D curves on faces or surfaces in case there are no 2D curves.
Thus, such methods of IntTools_FaceFace algorithm as TolReached3d(), TolReal() and TolReached2d() have been removed.
Now the tolerances of the curve can be obtained from the curve itself (IntTools_Curve - result of intersection):
- IntTools_Curve::Tolerance() - returns the valid tolerance for the curve;
- IntTools_Curve::TangentialTolerance() - returns the tangential tolerance, which depends on the size of the common
between faces. Currently, this tolerance is computed for Plane/Plane cases only. For other case, the value
of the tangential tolerance is the maximal tolerance of faces.
2D intersection tolerance (IntTools_FaceFace::TolReached2d()) has been completely removed from the algorithm as unused.
1. The packages *QANewModTopOpe*, *QANewBRepNaming* and *QANewDBRepNaming* have been removed as containing obsolete features.
The corresponding QA commands (such as OCC252, OCC307 and OCC294) and test cases have also been removed.
2. The QA command buc60609 has been removed. The corresponding test case bugs/moddata_1/buc60609 has been rewritten using b2dclassify command.
1. The TestTopOpe* packages have been removed.
2. The commands *compare*, *issubshape* and *projponf* have been moved to BRepTest package.
3. The possibility to change the Extrema options has been added to projection algorithm (GeomAPI_ProjectPointOnSurf).
4. Documentation has been updated.
1. The CellsBuilder algorithm has been extended to work with multi-dimensional arguments.
It has become possible not only simulate Boolean expressions, but also perform non-supported
Boolean operations, like cutting face from solid, or fusing face with edge.
2. Test cases with multi-dimensional input shapes have been created.
3. Documentation has been updated.
1. Removal of the traces of the usage of old Boolean operations in BRepFeat package.
2. The DRAW commands *fubl* and *cubl* based on old Boolean operations have been removed.
The alternative for these commands are the commands *bfuseblend* and *bcutblend* respectively.
The last two commands are based on the modern Boolean operations.
3. The DRAW command *ksection* based on old Boolean operations has been removed.
The command *bsection* should be used as alternative.
Test cases which have been using the *ksection* command have been modified to use the *bsection* command.
4. The class QANewBRepNaming_BooleanOperation has been modified to use modern Boolean operations.
The class QANewBRepNaming_BooleanOperation has been removed as not used.
The class QANewBRepNaming_BooleanOperationFeat has been renamed to QANewBRepNaming_BooleanOperation as it has nothing to do with Feat algorithm.
- The methods "Modified" and "IsDeleted" have been added for history support in "ShapeUpgrade_UnifySameDomain" class.
- The new Draw commands "unifysamedommod" and "unifysamedomisdel" have been added.
- Adoption of other algorithms using this one to its new behavior.
Removing code duplication
Correcting regressions
Correcting remarks
1. The partition operation allows splitting an arbitrary number of shapes of an arbitrary dimension
by other arbitrary shapes. The algorithm has been implemented in the class BOPAlgo_Splitter.
The API operator Splitter has been implemented in the class BRepAlgoAPI_Splitter.
2. The draw commands for usage the new algorithm have been implemented - bsplit and bapisplit.
The commands are identical, but one uses the BOPAlgo_Splitter, the other uses BRepAlgoAPI_Splitter.
Both commands should be used after Pave Filler is filled.
3. Test cases for the new algorithm.
4. Documentation has been updated.
Small corrections.
Enumeration Image_PixMap::ImgFormat, previously declared as nested
enumeration within class *Image_PixMap*,
has been moved to global namespace as Image_Format following OCCT coding rules.
The enumeration values have suffix Image_Format_ and preserve
previous name scheme for easy renaming of old values.
E.g. Image_PixMap::ImgGray become Image_Format_Gray.
Old definitions are preserved as depreacated aliases to the new ones.
1. The two new methods have been implemented:
a. BOPAlgo_Tools::EdgesToWires - allows creating planar wires from edges.
The input edges may be not shared, but the output wires will be sharing the coinciding vertices and edges.
It is possible to skip the sharing if the input edges are already shared by passing the corresponding flag into the method.
The input edges are expected to be planar, but the method does not check it. Thus, if the input edges are not planar, the output wires will also be not planar.
In general, the output wires will be non-manifold and may contain free vertices.
b. BOPAlgo_Tools::WiresToFaces - allows creating planar faces from the planar wires.
In general, the input wires are non-manifold and may be not closed, but should share the coinciding parts.
The wires located in the same plane and completely included into other wires will create holes in the faces built from bigger wires
These two methods combined allow building faces from set of edges randomly located in 3D space.
2. The DRAW command *edgestofaces* has been implemented.
3. The documentation has been updated with the new section in Modeling Algorithms - Topological Tools.
4. Test cases for the issue.
Macro NO_CXX_EXCEPTION was removed from code.
Method Raise() was replaced by explicit throw statement.
Method Standard_Failure::Caught() was replaced by normal C++mechanism of exception transfer.
Method Standard_Failure::Caught() is deprecated now.

Useless writes of intermediate shapes to hardcoded paths are removed in samples\mfc\standard\02_Modeling\src\ModelingDoc.cpp
Methods IGESBRep::WriteShape(), XSControl_Utils::WriteShape() are deleted; BRepTools::Write() can be used instead.
Method TopOpeBRepBuild_Tools::DumpMapOfShapeWithState() is moved to where it is used -- TopOpeBRepBuild_Builder1_1.cxx as static function (commented out).
Unused DRAW command OCC18612 is removed.
Upgrade Guide is corrected to avoid Doxygen warnings.
Table of supported operating systems with versions is removed, in favor of more general statement with simple list of supported OS and architectures.
Outdated list of tested graphic cards has been dropped.
1) In Views menu the check button item "Extended view commands" has been added. Pressing on it shows/hides the set of buttons in the main window that allow manipulating of view zoom/pan/rotate by mouse.
2) New category of commands "Vector and measurement Commands" has been added. The commands in this category allow simple calculations using 2D and 3D vectors, such as cross and dot products, computation of distances of points to other objects, and other functions.
3) The new command "pickf" has been added in "DRAW Variables management" category. It allows extracting a picked with mouse face included in some shape as a new variable.
4) New commands "del" and "era" have been added in "DRAW Variables management" category. They allow deleting (destructing) or erasing (from view) variables matched by glob pattern.
5) Missing help for some commands like "don", "disp" and others has been added.
1. The methods PerformVZ, PerformEZ, PerformFZ and PerformZZ have been transferred from BOPAlgo_PaveFiller to BOPAlgo_CheckerSI class
to perform intersection of sub-shapes with solids only in self-intersection mode.
2. The checks for solids built from the same (shared) faces have been added into methods building the result of Boolean operations -
BOPAlgo_BOP::BuildRC() and BOPAlgo_BOP::BuildSolid().
3. Since the NonDestructive mode is now natively supported by the BOPAlgo_PaveFiller the methods providing the support of this mode by CheckerSI
(BOPAlgo_CheckerSI::PrepareCopy() and BOPAlgo_CheckerSI::PostTreatCopy()) are not needed and have been removed.
4. The pairs of sub-shapes with interfering bounding boxes are now sorted before real intersection to guarantee the constant order of
intersection of sub-shapes and produce more stable result. The class BOPDS_PassKey has been replaced with simpler class BOPDS_Pair.
5. The class BOPDS_SubIterator has been refactored.
6. Test cases for the issue.
7. Adjustment of the test case boolean volumemaker D2.
1. There has been implemented calculation of all possible types of continuity for shared edges:
* G1 is set if tangential planes are the same for connected faces in each control points through the edge;
* C1 is set in addition to G1 conditions if derivatives, orthogonal to the edge on each face, are equal vectors;
* G2 is set in addition to G1 if the centers of principal curvatures are the same for connected faces in each control points through the edge;
* C2 is set in addition to C1 and G2 if directions of principal curvatures are equal;
* CN continuity is set only if both connected faces are based on elementary surfaces (the conditions for this case are similar to C2 continuity).
2. ShapeFix::EncodeRegularity() is merged into BRepLib::EncodeRegularity().
3. Implemented several test cases to check correct handling of regularity.
4. Fix incorrect usage of BRepLib::EncodeRegularity() in BRepBuilderAPI_Sewing.
5. Implement a method for calculation of regularity on the given list of edges.
6. Documentation updates

Now, GeomPlate_BuildPlateSurface accepts base class Adaptor3d_HCurve and of course array of Adaptor3d_HCurve.
Classes GeomPlate_Array1OfHCurveOnSurface and GeomPlate_HArray1OfHCurveOnSurface have been renamed to GeomPlate_Array1OfHCurve and GeomPlate_HArray1OfHCurve correspondingly.
Documentation has been updated.
Correction in documentation.
1. The result of Boolean operation on the arguments of collection type, containers WIRE/SHELL/COMPSOLID, is also a collection.
The containers of type WIRE included into result should now also (as the SHELLs) have coherent orientation of its sub-shapes.
For that the new method has been implemented (BOPTools_AlgoTools::OrientEdgesOnWire(TopoDS_Shape&)) which reorients edges for correct ordering.
The duplicating containers, i.e. containers with the contents completely included in other containers, are now avoided in the result of BOP.
2. The result of Fuse operation on Compsolids is now also will be Compsolid.
3. Documentation has been updated.
4. New test cases for the issue.
5. Adjusting test cases to current behavior.
Correction of test case bugs/modalg_4/bug726_2 according to the new behavior
Added toolchain file for using built-in Android cross-compiling support in CMake 3.7
Added variable CMAKE_ANDROID_STL_TYPE for Android platform build via CMake.
Updated documentation about building of occt for UWP and Android via CMake.

AIS_InteractiveContext - removed the following unused properties:
- PreSelectionColor(), DefaultColor(), WasCurrentTouched(), ZDetection().
AIS_InteractiveObject - removed unused property SelectionPriority().
Prs3d_Drawer - removed properties HighlightStyle() and SelectionStyle().
Graphic3d_HighlightStyle has been superseded by Prs3d_Drawer
inheriting from new class Graphic3d_PresentationAttributes.
Graphic3d_PresentationAttributes (as Graphic3d_HighlightStyle replacement)
has been extended with new properties:
- ZLayer() defining Z-Layer for highlighting presentation.
- DisplayMode() defining display mode for highlighting.
StdSelect_BRepSelectionTool methods have been corrected to take
SelectMgr_EntityOwner instead of StdSelect_BRepOwner.
StdSelect_Shape - duplicated field myDrawer has been dropped.
AIS_InteractiveObject - myDrawer->Color() is now used instead of myOwnColor,
myDrawer->Transparency() instead of myTransparency
and myDrawer->ZLayer() instead of myZLayer.
PrsMgr_PresentationManager::Unhighlight() now unhighlight all modes.
The method taking Mode as argument has been marked deprecated.
New enumeration Prs3d_TypeOfHighlight has been introduced
defining different highlight types.
AIS_InteractiveObject::HighlightStyle() now takes enumeration argument
and defines different styles for Global and Local selection.
ComesFromDecomposition() property has been moved
from StdSelect_BRepOwner to SelectMgr_EntityOwner.
1. The possibility to prevent addition of internal parts has been added into the following algorithms:
- BOPAlgo_BuilderFace;
- BOPAlgo_BuilderSolid;
- BOPAlgo_MakerVolume.
Setting the option to avoid internal parts for MakerVolume algorithm guarantees that the result solids
will be manifold and not contain any internal parts. But it does not prevent from occurrence
of the internal edges or vertices in the faces.
2. The Set/Get methods of the BOPAlgo_BuilderArea class have been made inline.
3. Draw command mkvolume has been updated to take into account the new option.
4. BRepOffset_MakeOffset::BuildShellsCompleteInter() has been modified to use the new option of BOPAlgo_MakerVolume
to speed up the construction of the final result solid.
5. Documentation has been updated with new section dedicated to BOPAlgo_MakerVolume algorithm.
6. Test case for the issue.
Added information about removed classes StdPrs_WFDeflectionShape,
Prs3d_WFShape, StdPrs_ToolShadedShape and removed property
AIS_InteractiveObject::SelectionMode().
The Gluing operation is an additional option for the algorithms in the Boolean Component
such as General Fuse, Boolean operations, Section operation, Maker Volume and Cells Builder algorithms.
The Gluing options have been designed to speed up the computation of the interference among arguments of the operations on special cases,
in which the arguments may be overlapping but do not have real intersections between their sub-shapes.
This option cannot be used on the shapes having real intersections, like intersection vertex between edges,
or intersection vertex between edge and a face or intersection line between faces.
The Gluing option is an enumeration implemented in BOPAlgo_GlueEnum.hxx. There are following items in the enum:
* BOPAlgo_GlueOff - default value for the algorithms, Gluing is switched off;
* BOPAlgo_GlueShift - Glue option for shapes with partial coincidence;
* BOPAlgo_GlueFull - Glue option for shapes with full coincidence.
For setting the Gluing options for the algorithm it is just necessary to call the SetGlue(BOPAlgo_GlueEnum) method with appropriate Glue value.
For using this option in DRAW the command bglue has been implemented:
* 0 - default value, Gluing is off;
* 1 - for partial coincidence;
* 2 - for full coincidence
Elimination of the warnings.
New topology-preserving offset algorithm has been added. It allows to construct offset shape of build solid.
test cases have been added.

Changed argument name in template class NCollection_Datamap to eliminate redefinitions of static members in dependent code.
Generation of header files from resource files was added to CMake and genproj procedures.
Message_MsgFile has been extended with new method ::LoadFromString()
for loading messages from embedded resources.

Shaders/Declarations.glsl and Shaders/DeclarationsImpl.glsl
are now embedded into OpenGl_ShaderProgram.cxx.
CSF_ShadersDirectory is no more required for using OCCT 3D Viewer.
Ray-Tracing GLSL programs from Shaders are now embedded into OpenGl_View_Raytrace.cxx.
