This reverts commit c479c4f6d89ed7c5e33dd35a5e110f13776b7cab.
The problem related with no changes on the ShapeHealing stage.
ReShape do not propagated well for all scenarios.
The test case update is not relevant.
Limited support of metadata import is added to RWGltf_GltfJsonParser.
Following Json data types are currently supported: int32, double, string,
array of int32, array of double, array of strings, Json object.
Notable unsupported types are: binary data, array of Json objects.
Metadata is processed for nodes and meshes.
Tests "gltf_export" are updated with import testing and renamed to "gltf".
Method RWGltf_GltfJsonParser::gltfParseSceneNode() is slightly
refactored: parsing of transformations and transformation matrices is

Implement PCH for TKDEIGES, TKDESTEP, TKMesh, and TKXSBase.
XShow and XDisplay XDE require VISUALIZATION for correct work.
In some scenario DRAWEXE can generate a duplicates of the internal static singletons.
This means each dynamic library will have their own instance of the static singleton.
Update all direct library loading to use the XDE plugin mechanism.
This will ensure that the XDE plugin is loaded only once and that the correct instance is used.
Originally issue is reproduced only Linux with dlopen with "RTLD_LAZY".
Can be resolved additionally adding "RTLD_LAZY | RTLD_GLOBAL" for dlopen
DCAF require VISUALIZATION for correct work.
In some scenario DRAWEXE can generate a dublicates of the
internal static singletons. This means each dynamic library
will have their own instance of the static singleton.
Update all direct library loading to use the DCAF plugin
mechanism. This will ensure that the DCAF plugin is loaded
only once and that the correct instance is used.
Originally issue is reproduced only Linux with dlopen with "RTLD_LAZY".
Can be resolved additionally adding "RTLD_LAZY | RTLD_GLOBAL" for dlopen

Symlink creates link to the origin file, it has some benefits from debug and build side.
The CMake parameter for symlink is 'BUILD_INCLUDE_SYMLINK'
Removed or reorganized include that are not a part of the project dependency.
The new file for typedef is added because Select is not direct dependency.
Processing of complex_triangulated_surface_set is added to
STEPCAFControl_GDTProperty::GetTessellation().
Processing of tessellated_curve_set is refactored and moved to a
separate function.
Problems related to normals list are fixed in
RWStepVisual_RWComplexTriangulatedSurfaceSet::WriteStep():
Normals list is now checked for nullptr. It is a valid situation that
occurs when complex_triangulated_surface_set in STEP file has no
normals.
Traversing of normals list is performed in correct order. Previously
rows and columns were switched, which led to crashes or incorrect data.
Windows, Linux builds now starts checking the warning.
In warning case the job will be failed.
MacOS having too much warnings related with sprintf.
Linux Clang having a problem with Flex and Bison.
TODO: Fix the warnings for MacOS and Linux Clang.
Fixed exception in RWStepShape_RWEdgeCurve::Check() thrown when trying
to access step entity in Interface_EntityIterator with zero entities.
Fixed a crash in StepToTopoDS_TranslateFace::Init() caused by
dereferencing nullptr.
RWStepShape_RWEdgeCurve and RWStepShape_RWEdgeCurve are refactored.
Test bug33665 is added to check the fixed behavior.
Precision.hxx optimized to have compiler-time
constants for the most common floating-point values.
Reorganized code to avoid static jumping for parametric.
The absence of target_link_libraries calls for static libraries caused CMake to fail
in modeling the link dependencies correctly.
This fix ensures that CMake correctly exports the dependencies in OpenCASCADEConfig.cmake and
resolves downstream linking errors for projects that link against static OpenCASCADE libraries.
Removed unnecessary tolerance increase for Line\Line intersection.
Tolerance increasing logic for some specific curve types
was added with #26619.
Original fix had no test for Line/Line case and
theoretically was added as a possible issue.
After research Line/Line case doesn't need a special tolerance case.
Pass ShapeBuild_ReShape to recursive call to retrieve complete change history.
Update history of changes by the source shape (if changed), not only by its subshapes.
Check the context for a cached shape using a reference shape without location.
The reason of current problem lies inside projection algorithm
Function_SetUVBounds() for projection of circle onto sphere produces shifted bounds.
Incorrect checking of placement on summit of the sphere was fixed.
Changed condition for combination of WLines into one.
WLine would be excluded from consideration for merging, if one of its middle points between vertices is out of domain (does not lie on both surfaces).
This problem occurs because of obtaining 2 ALines which share same vertex on the seam edge.
There should be 2 different vertices with same(or almost the same) 3d parameters, but
with different UV parameters because of periodic surface.
Current fix allows to avoid the same vertices on seam edge and also checks the next vertex.
Added consideration of predicted next point to avoid skipping tha point which is not on seam edge.
Added test case for #33702
Added option to dump only a selection of zlayer's content.

Added test.
Added protection against null pointer dereferencing.
Modified BRepOffset_MakeOffset::MakeThickSolid method.
Fixed the problem with negative volume values.
Fixed several unit tests and added a new one.
Handling of special case found on some STEP files produced by FPX Expert 2013 (PCB design system):
edge curve is line displaced from its true position but with correct direction;
we shift the line in this case so that it passes through vertices correcty.
Protection against possible exception in writing XDE.
ProjCurve3d and BRepAlgo_FaceRestrictor::Perform functions should not continue to work and should terminate if the BRep_Tool::Curve function returns null pointer.

in order to support link of components according to ISO 10303-203-2003.
Datum reading changed in ReadDatums() method:
using DatumSystemAP242 (DatumSystem or DatumReference) array
instead of DatumSystem array (DatumReference)
The new transform persistence mode, with flag `Graphic3d_TMF_OrthoPers`, can be combined (bitwise OR operation) with the other persistence modes (2D, Trihedron or Zoom/Rotate Persistence) to make objects be rendered with orthographic projection when it is on a view with perspective projection.
If the view already uses orthographic projection, there will be no difference.
This feature was implemented to fix ViewCube being distorted when view with perspective projection changes size.

Added support of reading and writing of the triangulated_surface_set.
Prevented creation of tesselated geometry under the schemas different from AP242DIS.
test step_read corrected, switched parameter write.step.schema to AP242DIS in begin and back to AP214CD at the end
Selecting the middle point between XInf and XSup leads situation, where X values almost does not change.
To prevent this situation, select shifted point instead of middle.
Changed iteration limits from theTriangulation->NbTriangles() to theTriangulation->NbNodes()
Provided modification of the normals only with rotation (gp_GTrsf::Form() == gp_Other leads to crash)
Added condition to not remove face image, consisting only of invalid edges for artifactically invalid face.
This face image should be connected with other image faces minimum through the edge.
Pass pointer to DEXCAFCascade_ConfigurationNode to DEXCAFCascade_Provider;
Remove forcible manual reset of Provider's node in DE_Wrapper::FindProvider() to verify that all specializations of configuration node work properly without necessity of workarounds.
Crush occurred due to the fields
IntTools_SurfaceRangeLocalizeData::myUParams,
IntTools_SurfaceRangeLocalizeData::myVParams
and IntTools_SurfaceRangeLocalizeData::myGridPoints not being checked
for NULL in some cases.
Missing checks are added.

Created new module - DETools to keep tools to DE
Changed definition of main of ExpToCasExe to not const parameter
FlexLexer.h moved to general location into TKernel
Removed double healing of Iges group entities
Added ShapeBuild_ReShape member to the IGESData_IGESModel class, shapes which are registered in ShapeBuild_ReShape class does not process to healing
WSL 2 have windows FileSystem and as a result we have \r symbols before \n
For this cases we can just remove \r\n (\n is a last symbol) for the node value.
BRepBndLib.cxx : treatment of useTriangulation is modified according to specified behavior of algorithm
BRepTest_CurveCommands.cxx : creation edge from polygon3d is added in Draw command mkedge.
Fixed problem with pure referencing.
To export reference label to step we convert it to the assembly with one part.
All attributes attached to the label should be moved to the new part.
For working with it new map contains only pure reference labels, that converted to the part
was implemented to the STEPCAFControl_Writer.
Updated code style of the STEPCAFControl_Writer
Improved ability to export labels from different documents
Removed OCCT_Debug macros to print in Trace gravity
Improved objects sorting by depth.
The sensitivity calculation for the manipulator has been changed.
Now the sensitivity of the elements of the manipulator depends on its size.
Also fixed the problem of erroneous selection of unfilled circles (SelectMgr_Frustum<N>::hasCircleOverlap() function).
Test case vselect/bugs/bug27848 added.
Added two new overloaded methods XCAFDoc_ShapeTool::GetOneShape: one returns TopoDS_Shape from TDF_LabelSequence and the other from a sequence of all top-level shapes which are free
When using AIS_AnimationObject, linear interpolation is performed from one gp_Trsf transformation to another.
But when an object rotates around a specific axis, the object moves not along a linear trajectory,
but along a circle. Therefore, a separate class AIS_AnimationAxisRotation was created that
allows to animate rotation around a specific axis.
Test case tests/v3d/bugs/bug32570 was added.
ReWork UpdateLoad functionality:
UpdateLoad calls only if provider is found.
UpdateLoad calls only for chosen type of translation (read/write)
Add new method to UpdateLoad all registered nodes.
Exception no longer occurs in current version. However, fuzzyvalue should be set to 1 for the result of the operation to make sense (result of common is 1 wire). Test case added
test bugs modalg_7 bug22821 failed on fillet shape with 5-th edge.
Experimentally has been found that reducing of parameter
ChFi3d_Builder::tolesp for this task solves the issue.
So, as soluton it is proposed to link parameter toleps with parameter range of
spine curve. So, production coefficient has been set to pass all tests and
2 teset was extended: tests/blend/complex/A6, tests/bugs/modalg_7/bug22821
first has been extended to test different scaling factors,
second has been extended to make fillet on all edges from 12.
Additionally:
- fixed misusage of tolesp in contexts where tolerance of point in 3d is excepted;
In some context usage of tol_esp is irrelevant, because its essentiality - tolerance of the parameter on the 3d curve.
So, in such context it has been replaced with new parameter tol3d (with fix value 1.0e-4).
Get rid of tolapp3d duplication constant - tol_3d
- tolesp = 5.0e-5 * (umax - umin)
- tolesp replaced by tolpoint2d/tolpoint3d in several classes.
Blend_Walking
BRepBlend_SurfRstLineBuilder
BRepBlend_RstRstLineBuilder
Blend_CSWalking
Instead `tolesp` - `tolgui` is employed in contexts where tolerance of guide curve parameter is excepted.
Instead `tolesp` - `tolpoint2d` or `tolpoint3d` is employed in contexts where tolerance of point in 2d or 3d space is excepted.
- Replace tolesp with tolpoint2d/tolpoint3d in BBPP function argument.
- Use tolapp3d instead tolesp in BonVoisin function,
distmini of two edges returns two solution points instead one.
Second unneeded solution point is the same as first.
The problem was in fact that second edge has continuity C0.
In this case additional extremas analysis performed in special procedure
PERFORM_C0
And second point found in this procedure.
Folowing code of
BRepExtrema_DistanceSS::Perform (variant for Edge/Edge)
we should this additional solution extremas set
to be object of test TRI_SOLUTION before pushing
into main list of solution.
This solves the problem.
Corresponding test and compound with edges has been created.
Additionally, in the function
PERFORM_C0
an obvious error has fixed.
Problem: The shape has two faces that dimensions are less than tolerance in the specified STEP file. This situation produces the invalid shape.
Change: Shape process has operator FixFaceSize, that is exactly suitable for this shape. The only option of FixFaceSize operator was added to InterfaceStatic, to manage the operator from DRAW command.
Result: The shape without artifacts can be reproduced from STEP file with an extra healing procedure.
BSplCLib_2.cxx - method MergeBSplineKnots is modified in order to have always not empty result.
Geom2dConvert.cxx - in static function MultNumandDenom tolerance for comparing knots is decreased.
tests/bugs/modalg_8/bug33179 test case added
BRepOffset_MakeOffset.cxx - tolerance control for building planar faces is implemented,
updating tolerance for initial entities is avoided
BRepAlgo_Loop.cxx - "total" setting tolerance 0.001 is removing
BRepLib.cxx - checking of "locked" for vertex is removing in static function UpdShTol
QABugs_20.cxx - add new command OCC26441 for checking tolerance differenses between two "identical" shapes
tests/bugs/modalg_7/bug30054 - case now is "BAD", because really result shape is invalid: many faces has not closed wires with huge gaps between ends of edges. Result was "OK" only because tolerances of vertices were increased by algorithm to cover all gaps.
tests/bugs/modalg_8/bug26441 - new test case added
Other test: B3, C8, A7, C8: they were "BAD" and now are "BAD", only some problems are changed.
Problem: Desynchronization of behaviors of GeomAdaptor_Curve::NbIntervals and
GeomAdaptor_Curve::Intervals functions. First calculates number of intervals, then
array is created and second fills the array. In some cases the size of array
is less than need for filling.
Change:
1. Added function BSplCLib::Intervals that calculates number of interval and fills
the array with its (if needed).
2. Simplified the algorithm of intervals calculation.
3. GeomAdaptor_Curve::NbIntervals/Intervals and Geom2dAdaptor_Curve::NbIntervals/Intervals
use BSplCLib::Intervals.
4. When creating an adapter for the base curve, the boundaries of the adapter for the offset curve are applied.
5. Test for problem shape was created: bugs modalg_8 bug33187.
Result: The new approach eliminates the problem of writing outside the array bounds.
Added step of refinement the coarser of the two shapes meshes to produce two meshes with approximately the same density.
Added tests lowalgos/proximity.
Fixed accounting of parameters to adjust number of initial sample points
GeomLib_IsPlanarSurface.cxx - using poles for checking BSpline, Bezier curves and surface changed
on checking by curve, surface points.
BRepOffset_MakeOffset.cxx - set normal of plane surface according to normal of initial face surface
tests/cr/bugs/bug33170 - new test case added
Added new CMake variables to build using DRACO
Windows OS works with Debug and Release configuration DRACO
Linux works with Release configuration DRACO
Fix warnings:
* catching polymorphic type 'class Standard_Failure' by value [-Wcatch-value=]
* this 'if' clause does not guard... [-Wmisleading-indentation]
ShapeAnalysis::OuterWire(): fixed missed logic when TopoDS_Iterator notifies about more objects to iterate, but there are only vertices and no additional wires at all.
Add parameter EnableControlSurfaceDeflectionAllSurfaces to IMeshTools_Parameters enabling possibility to optimize mesh even on analytical surfaces;
Add corresponding parameter -surf_def_all to incmesh Draw command.
Method IntWalk_PWalking::ExtendLineInCommonZone(...) now is not called if the already found intersection point is on surface boundary.
As result, the intersection line going along any boundary will never be extended. It is appropriate for high-level OCCT-algorithm because they will take the boundary (not computed line) as intersection result.
Increase minimum number of discretization points by one explicitly on each iteration of model healer to cover cases degenerated to line (for cases when face consists of 2 edges only).
Fixed the Toroidal surface recognition;
The test case bugs/moddata_1/bug22296: the result is a torus with parameters: u [0, 2*PI], v [PI, 3*PI];
The test case bugs/modalg_5/bug23954: BAD -> OK.

Proposed solution: turn off cotire from targets, whose compilation cause error while applying cotire tool.
In this ticket migration to cotire 1.8.1 (from 1.7.9) is done.
COTIRE_PREFIX_HEADER_IGNORE_PATH does not apply here, because its employing
causes some errors in 3rdparty libraries (for example, in TKService project).
Projects (TKDFBrowser TKMessageModel TKMessageView TKShapeView TKTInspector TKTreeModel TKVInspector TKView)
which use Qt may be proceeded by cotire tool, but after fixing a bug of cotire:

After emploing intel oneTBB of version 2021.5 on NEXT platforms arises error on OCC Pr.:
`
*/ld: */libfreetype.a(truetype.o): relocation R_X86_64_PC32 against symbol `TT_RunIns' can not be used when making a shared object; recompile with -fPIC
*/ld: final link failed: bad value
`
Proposed solution: linking with shared object of libfreetype, rather than with archive library.
Despite that error occurred only in OCC Pr., it is worth to accept changes for OCCT too.
Previous approach do not taking into account, that oneTBB library may be installed in the system folder
on Linux. So, solve the problem it is proposed to employ find_package utility, that works great
as on Windows, as on Linux.
Problem: From the point of view of the STEP format (and others), it is allowed
to describe a face on a surface with natural boundaries (torus, sphere) without
specifying these boundaries. Thus, a face on a closed surface and containing
an inner wire (or several) is correctly defined and describes a face with a
cutout defined by this wire. At the same time, there is a function
(ShapeFix_Face::FixOrientation) in the ShapeHealing procedure that corrects the
orientation of the wires, and it starts before the function of adding natural
boundaries (ShapeFix_Face::FixAddNaturalBound). There are many shapes that have
incorrectly oriented wires and this procedure successfully heals them, but on a
correctly specified face with single inner wire on closed surface, we do not get
the entire surface with a cutout, but a part of the surface defined by the wire.
This fix is intended to resolve this ambiguity.
Change:
1. Added function isNeedAddNaturalBound that returns TRUE if face needs to add
natural bounds.
2. Corrected condition in FixOrientation to ignoring faces that needs to add
natural bounds.
3. For tests in which one wire was incorrectly oriented on a closed surface,
flag AddNaturalBound was disabled.
5. Test with cutout from torus was created: bugs step bug28414.
Result: By default, it is correct to add natural boundaries, because this case
is correct from the point of view of the STEP format and others.
Problem: There is no possibility to change shape healing options from DRAW without rewriting resource file.
Change: Shape healing parameters from STEP and IGES resource files were duplicated to InterfaceStatic. Resource manager initialize from InterfaceStatic if resource file name is empty.
Result: User can operationally change shape healing parameters from DRAW command using "param" command.
Currently directory containing tbb 3rdparty installation should match the template tbb*.
But after using oneTbb of version 2021.5 standard installation directory is onetbb*.
So, for this 3rdparty modify searching template.
Adapt test case, the problem is not reproduced any more.
Problem is fixed by the commit: 46478ffe32cfca537a35b744700e082f59ec4c4c (0030008: BRepMesh does not respect angular deflection in internal area of bspline surface)
MSVC 2022/c++20.
After employed c++20 language standard errors of compilation in intel oneTBB occurred.
To get rid of compilation errors proposed moving on actual (2021.5.0) intel oneTBB occ products and occt.
After migration errors of compilation of TKernel and TMath have been occurred...
...Error occurred if using c++20 standard with new oneTBB 2021.5.0.
The error was:
Error C2672 'tbb::v1::parallel_for_each': no matching overloaded function found TKernel
could be 'void tbb::detail::d2::parallel_for_each(Iterator,Iterator,const Body &)' TKernel
'tbb::detail::d2::parallel_for_each': the associated constraints are not satisfied TKernel
Note, that if we use c++14 or c++17, all ok, error does not occures.
To solve the problem, i have to modify `UniversalIterator` class:
`value_type` instead `UniversalIterator` converted to `IteratorInterface*`
`pointer` = `reference` = `value_type`
Method `DownCast` moved into `FunctorInterface` abstract class.
argument `UniversalIterator& item` of the unary fuctions converted to `IteratorInterface*`.
The proposed solution removes compilation error.
Affected projects: TKernel, TMath
Affected sources: src/OSD/OSD_Parallel.hxx, src/OSD/OSD_Parallel_Threads.cxx
Affected classes: class OSD_Parallel, OSD_Parallel::UniversalIterator, OSD_Parallel::FunctorInterface, OSD_Parallel::FunctorWrapperIter, OSD_Parallel:;FunctorWrapperInt.
- ShapeFix_Face::FixMissingSeam method is fixed in order to handle degenerated torus
- Calculation of degenerated torus bounding box is fixed

0032422: Mesh - Weird rendering
0029641: Mesher produce 'bad' result for extruded spline with given deviation coefficient
Added method BRepMesh_NURBSRangeSplitter::getUndefinedInterval() intended to compute checkpoint parameters for those NURBS surfaces which have no intervals at all. In this case number of poles is used to produce artificial regular grid which can be refined further. Add at least one midpoint for surfaces with one interval and only two poles.
Added BRepMesh_ExtrusionRangeSplitter and BRepMesh_UndefinedRangeSplitter derivatives from BRepMesh_NURBSRangeSplitter intended to handle special cases of extrusion surfaces and general surfaces with undefined parameters.
Extend "proximity" command to be able to compute the proximity value;
Implement classes for calculate proximity value between two shapes;
Add possibility to set up the number of sample points for the input shapes;
Add tests lowalgos/proximity.
Make C++ standard to be enable from cmake settings:
User will be able choosing C++ language standard by selecting cmake variable BUILD_CPP_STANDARD.
For correct working, CMAKE_CXX_STANDARD cmake built-in variable should be available.
To enable CMAKE_CXX_STANDARD, minimum CMAKE version has been updated to 3.1.
Available next standard items:
C++11
C++14
C++17
C++20
C++23
This issue consists from several steps to achive main goal:
1) Configuratiuon, CMake - allow selecting C++ standard.
2) Require minimum CMAKE version 3.1 (for enabling CMAKE_CXX_STANDARD).
3) More flexible CMAKE_CXX_COMPILER_ID identification (fixups previous commit!)
4) Add description of new CMAKE variable `BUILD_CPP_STANDARD` into documentation.
5) Update CMAKE requirements in documentation.
6) Set C++11 standard for several projects.
Integration of ExpToCas tool ported to modern state of OCCT:
- new package Express and toolkit TKExpress for EXPRESS data structures and OCCT class generator
- executable ExpToCasExe including lax/yacc parsers, for parsing a Part 21 file and generating classes
Formatting added files from package Express following OCCT Coding Rules
Changes for correspondence generated files to OCCT Code Rules.
Add generation hxx files with declaration of arrays.
If field is a HArray1 method for get length of array and method for get element of array by its index are generated.
Changes for generation parser from Lex and YACC files.
Update description file ReadMe.md
While demanding c++ language standard c++20, the error of OCCTProxy compilation is occured:
warning C4857: C++/CLI mode does not support C++ versions newer than C++17; setting language to /std:c++17
error C7681: two-phase name lookup is not supported for C++/CLI or C++/CX; use /Zc:twoPhase-
Officially, C++/CLI mode does not support C++ version newer than C++17, so we should not demand C++20 to compile csharp samples.
Alternative solution - using /permissive (ConformanceMode = false), rather than default value /permissive- (ConformanceMode = true)
option to compile OCCTProxy. But alternative solution has been denied.
So, here is nothing to do to fix compilation of OCCTProxy project.
Nevertheless, error occures in IE_WPF_WinForms and IE_WinForms - if we trying to compile with VC++ 2022 (not demanding c++20):
warning MSB3274: The primary reference "*\OCCTProxy.dll" could not be resolved because it was built against the ".NETFramework,Version=v4.7.2" framework.
This is a higher version than the currently targeted framework ".NETFramework,Version=v4.0".
To solve the problem it is proposed to demand by default the highest version of NETFramework - 4.8.
So, demanding NETFramework v4.8 does not crashing compilation of csharp samples with VC++ 2015.

Added the test for this ticket;
test case lowalgos/classifier/bug377: BAD -> OK
Select3D_SensitiveCircle now inherits directly from Select3D_SensitiveEntity.
The sensitive circle sector is created using the Select3D_SensitivePoly class directly.
Added appropriate methods for selecting sensitive circles.
Added parameter myIsHollow to Select3D_SensitiveCylinder class.
It allows you to search for intersections with cylinders without covers.
The Draw vcircle command has been extended with UStart and UEnd parameters
to create a sector of a circle.
Added tests: vselect/cone_cylinder/circle_sector
vselect/cone_cylinder/circle_wire
vselect/cone_cylinder/filled_circle

GeomConvert_CurveToAnaCurve, GeomConvert_SurfToAnaSurf - geometrical algorithms
for converting geometrical curve and surfaces in canonical geometry with given tolerance.
ShapeAnalysis_CanonicalRecognition - interface for checking canonical geometry.
Added Graphic3d_TypeOfBackfacingModel_FrontCulled enumeration value.
OpenGl_Context::SetFaceCulling() now supports GL_FRONT in addition to GL_BACK.

1. Multiple changes in ShapeUpgrade_ShapeDivideArea, ShapeUpgrade_FaceDivide, ShapeUpgrade_FaceDivideArea, ShapeUpgrade_SplitSurface, ShapeUpgrade_SplitSurfaceArea: new methods NbParts and SetSplittingByNumber, changes in ShapeUpgrade_FaceDivideArea::Perform and ShapeUpgrade_SplitSurfaceArea::Compute concerning new modes of splitting.
2. New Draw command "DT_SplitByNumber" for testing new modes of splitting.

Improved the processing for the case where Failure flag for the meshing face is set. Specific tests added.
Check triangulation consistency even for shapes with problematic topology given that they are suitable for keeping it.
Get rid of strange code: preliminary check of self-intersections is made on a polygonal representation of a curve, it is able to find possible intersections, but after that it filter out segments neighbor to the pair of non-intersected segments.
Test case de step_4 I1 has been marked BAD, because the self-intersection is treated correctly, but the projection algorithm generates such crooked 2D curve.
Reference data in test cases heal split_angle_advanced ZA5 and ZA6 has been updated, because those shapes have self-intersected edges, which are being detected now.
New XCAFDoc classes:
- XCAFDoc_AssemblyIterator: iterator in depth along the assembly tree
- XCAFDoc_AssemblyGraph: assembly graph with iterator
- XCAFDoc_AssemblyTool: provides generic methods for traversing assembly tree and graph
A method for re-scaling (sub-)assembly geometry is added to XCAFDoc_Editor.
New DRAW commands:
- XDumpAssemblyTree: iterates through the assembly tree in depth up to the specified level, if any
- XDumpAssemblyGraph: prints assembly graph structure
- XDumpNomenclature: prints number of (sub-)assembly/part instances
- XRescaleGeometry: applies geometrical scale to (sub-)assembly
Fix affects BFGS optimization methods by checking convergence as the first step on each iteration. FRPR works well, but it is updated as well since its logic potentially dangerous.
When creating a fillet, num is calculated via ChFi3d_IndexOfSurfData. If it
returns just the number of entries in surfdata, it can happen that this
value becomes invalid when handling the case "two faces common to the edge
are found". When both components are on an arc, there will be num removed
from the surfdata.
num would then be larger than the number of entries surfdata. The derived
num1 is therefore also incorrect. The subsequent usage of this
value will either:
* Debug build: cause an out of bounds exception in ChangeValue
(`SeqFil.ChangeValue(num)`)
* Release build: cause a segfault when retrieving it via index num1
(`SeqFil(num1)`)
num + num1 must be recalculated after the deletion happens to correctly
calculate the fillet.

The PerformIntersectionAtEnd code is currently not handling all the faces
correctly. If it retrieves Face[0] as F, it can happen that the previously
ran code didn't actually retrieve any faces in this array at all.
For example when:
* "if (nface==3)" is true
- "if (!findonf1)" is true (doesn't assign any faces to this array)
- "if (!findonf2)" is true (doesn't assign any faces to this array)
- "if (state == ChFiDS_OnSame)" is not true (because it is
ChFiDS_AllSame)
- "if (findonf1 && !isOnSame1)" cannot be true (see above, but would
handle faces)
- "if (findonf2 && !isOnSame2)" cannot be true (see above, but would
handle faces)
- "if (isOnSame2)" is false (but would also handle faces)
Since no faces were assigned here, F would be a NULL face. As result, the
function will crash when trying to access the Surface behind the face via
`BRep_Tool::Surface(F);`.
While the best approach would be to identify the implementation bug in the
algorithm behind PerformIntersectionAtEnd, a check + exception is used
instead because the actual algorithm is not known.

The ChFi3d_IsInFront code is currently not handling all the combinations
correctly. For example, if `if(fd1->IndexOfS2() == fd2->IndexOfS2())` is
true, it can happen that the `TopoDS::Face(DStr.Shape(fd1->Index(jf1)))`
returns a Face with entity == NULL. The subsequent usage of this NULL face
in `BRep_Tool::Parameters( Vtx, face )` will then cause a segfault.
While the best approach would be to identify the implementation bug in the
algorithm behind PChFi3d_IsInFron, a check + exception is used instead
because the actual algorithm is not known.

Support of reading and writing tessellated geometry is added for the following STEP entities:
- triangulated face
- complex triangulated face
- tessellated shell
- tessellated solid
- tessellated shape representation
Models without BRep geometry (mesh formats like STL, OBJ and so on) are supported for writing to STEP.
New parameters are added to enable/disable tessellated geometry reading and writing:
- read.step.tessellated (On/Off/OnNoBRep) (On by default)
- write.step.tessellated (On/Off/OnNoBRep) (OnNoBRep by default)
OnNoBRep - tessellation is read/written only for entities for which there is no BRep representation.
Faces with poly triangulation are written in STEP as triangulated face entities with one coordinates list per face.
Only one poly triangulation per face (returned by BRep_Tool::Triangulation) is written to STEP.
Added new option '-C' with possibility to set value of Angular and linear tolerances to 'mksweep' command to correct input spine by merging smooth connected neighboring edges
Problem: the complete surface of the torus is not stored correctly in STEP format due to the fact that the edges are not properly ordered.
Change: added a mode for reordering edges in the wire with simultaneous use of 2d and 3d information (ShapeAnalysis_WireOrder). The new mode is used for torus-like surfaces before saving to STEP format.
Result: Torus correctly stored.
SelectMgr_ViewerSelector::TraverseSensitives() now takes into account object's view affinity.
AIS_InteractiveContext::moveTo() - dropped code SelectMgr_AndOrFilter::SetDisabledObjects()
as filtering is now done by selector itself.
ViewAffinity property has been moved to PrsMgr_PresentableObject for simplicity.
Removed redundant map Graphic3d_CView::HiddenObjects().
Add choosing the intersect point taking into account the tangentCross when prev UEdge and next UEdge has more than one intersect points;

Get rid of warning C26440: "If your function may not throw, declare it noexcept"
"If code is not supposed to cause any exceptions,
it should be marked as such by using the 'noexcept' specifier.
This would help to simplify error handling on the client code side,
as well as enable compiler to do additional optimizations."
Put explicit type casting to avoid:
Warning C26451 Arithmetic overflow: Using operator '-' on a 4 byte
value and then casting the result to a 8 byte value.
Cast the value to the wider type before calling operator '-' to avoid overflow (io.2).
Code related to supporting of single SDR for a non-manifold group, which prevents writing all translation results except the first one, is removed.
SDRs with null used representation object are excluded from writing.
1. Modify method IntPatch_ALineToWLine::MakeWLine: add correction of end points of each line on 2 surfaces if an end point is a pole on a surface.
2. Modify method IntPatch_WLine::ComputeVertexParameters: adjust a point on curve to corresponding vertex the following way: set 3D point as the point of the vertex and 2D points as the points of the point on curve.

V3d_View/Graphic3d_CView pair has been extended to define subview within the other V3d_View instance.
The initialization is done in form of V3d_View::SetWindow() taking parent V3d_View instance on input.
Subview definition includes dimensions defined as a fraction of a parent view and offset from a corner.
This scheme allows splitting window into several subviews automatically occupying entire viewport,
like splitting window into two vertial subviews (100%x50% + 100%x50%),
three horizontal subviews (33%x100% + 30%x100% + 30%x100%),
1 + 2 stacked subviews (50%x100% + 50%x50% + 50%x50%),
as well as thumbnail-alike subviews displayed on top of another larger view.
OpenGl_View::Redraw() blits content of subviews into the window within immediate redraw step.
AIS_ViewController::FlushViewEvents() has been extended
to re-calculate mouse input into local subview coordinates.
AIS_ViewController::handleViewRedraw() first redraws subviews and then parent views.
Introduced new callback AIS_ViewController::OnSubviewChanged()
to switch input focus to another subview on mouse click,
implemented by ViewerTest_EventManager (has to be done at application level).
vinit command has been extended with parameters -subview and -parent to create a subview.
In addition, view dimension arguments now can be defined as a fraction of screen size instead of pixels.
Colors wasn't read correctly because of incorrect curve transfers in IGESToBRep_TopoCurve.cxx
I added new calls to SetShapeResult() at the necessary places.
Also in the IGESCAFControl_Writer.cxx I added new condition because of the possible NULL exception.

Fixed the problem of reading XML files on MacOS. 'errno' was not reseted
even the 'strtol' function produced a good value. So, now it is erased
forcibly before the call.
Incorrect curve handling.
If curve doesn't have trims and vertexes, we handle it such as trimmed curve, but it should be a simple curve.
Curves with only one vertex and one trim should handle by another way, such as a curve that has trims but doesn't have vertexes.
So I added conditions which handles these cases
Do not limit the normalization factor of the highly anisotropic parametric space when filtering start points in the algorithm of walking line construction.

test cases has been changed according to new behavior
A flag not to raise an exception is set for a copying shape. A reason: if a shape is already in the model, the user should have an opportunity to copy it.
Modified files:
TNaming_CopyShape.cxx, the method Translate(). A false-flag is used on copying of location of the shape.
Add the case of closed, smooth but not periodic surface (unification of faces lying on it if the flag "myConcatBSplines" is true - modify the underlying surface to make it periodic).
There is one case in PerformIntersectionAtEnd that did not test whether
an array access exceeded the length of the array, in rare cases
resulting in a segmentation fault. That error-handling behavior is
replaced by the exception code used elsewhere in the function. For
consistency, the code is copied exactly as implemented elsewhere. This
code has the same effect as that proposed by the bug submitter.
Added PLY writing tools RWPly_CafWriter and RWPly_PlyWriterContext.
Added tool BRepLib_PointCloudShape generating point cloud from shape in two ways:
- random points on surface with specified density;

2) New test grids (based on the previous ones) have been added. These new cases use locked shapes as input arguments
3) The option '-safe' has been added to 'thrusections' command
Add more faces for intersection in rebuilding process basing on the connection of the splits of offset faces (special treatment for the artificially invalid faces).
When rebuilding faces add vertices common for faces for trimming the new intersection edges.
Adjust existing and create new test cases.
A flag not to raise an exception is used on reading of an OCAF document. If such a shape with scaling transformation is stored in the document, it should be read.
Modified files:

Use distance criteria additionally to parameter criteria when verifying the extrema solution to belong to the edge boundary.
Refactor the BRepExtrema_DistanceSS class to remove the excessive methods with mirrored parameters.
Variables "toSimulator" and "anAbi" within "ios_custom.sh"
have been replaced by "anAbiList" which can be defined like "iPhoneOS|arm64 iPhoneSimulator|arm64".
Added "toPackFat" option packing multiple architectures into FAT archives.
A copy of myface is made, where further on the copy the geometry changes. We connect the face, wire, edge of the original shape with the one whose geometry was changed. This is done in order to get the original shape in the TransferWire() and TransferEdge() methods.
Added new enumeration Graphic3d_DisplayPriority.
Graphic3d_Layer now defines a fixed-length array of priorities.
Properties Graphic3d_CStructure::Id, Priority, PreviousPriority have been wrapped into methods.

In STEPCAFControl_Writer::WriteNames, write the names of components
even if the name of the assembly is absent.
In STEPControl_ActorWrite::TransferSubShape, move assembly structure
information to the beginning of the list of results, so that CDSR
information of this assembly became preceding CDSR of any sub shapes.
Prs3d_TextAspect now sets Font_NOF_SERIF as default font
instead of confusig Font_NOF_ASCII_TRIPLEX (Times-Bold).
Therefore, default font now uses regular aspect, not bold.
Command vdrawtext does no more set "Courier" font by default.
OpenGl_FrameBuffer::Init() now creates MSAA render buffer in case if MSAA textures are unsupported.
In this case OpenGl_View::prepareFrameBuffers() creates MSAA render buffer for main content
and non-MSAA FBO for immediate content as blitting of MSAA render buffers into MSAA targets is unsupported by OpenGL ES 3.0.
env.bat.in has been corrected to include path to custom ANGLE (GLES2_DIR)
in front of Qt which might include its own older ANGLE build.
Add '-exact' option to checkshape command to use exact method to validate edges using BRepLib_ValidateEdge class. Default mode is calculating in finite number of points.

_WIN32_WINNT in CMake configuration for MinGW has been raised from 0x0501 to 0x0601.
Implementation of new format for quick reading and writing parts of the documents (sub-set of labels and sub-set of attributes). It consists in writing shapes and all their contents right in the TNaming_NamedShape attribute placement and skipping the shape section. New format 12 for Binary file types is assigned to this version.
Added PCDM_ReaderFilter class that could be used in Open methods of TDocStd_Application. If it is defined, it allows to read:
- into already opened document in append mode AppendMode_Protect (do not overwrite existing attributes) or AppendMode_Overwrite
- only specified sub-trees of the document using AddPath (const TCollection_AsciiString& theEntryToRead)
- only specified attributes using AddRead (const TCollection_AsciiString& theRead) where theRead could be "TDataStd_Name", for example
- to skip specified attributes read using AddSkipped (const TCollection_AsciiString& theSkipped) where theSkipped could be "TDF_Reference", for example
The current limitations:
- only in Bin format
- if shapes have in the document shared topology, loaded in "append" mode in different "load" operations, they will have no shared topology anymore
Modifications:
BinLDrivers and BinDrivers packages - modifications related to the quick part tree format flag usage, skipping shape section writing and adding labels sizes into the document to be able to pass labels during the reading quickly.
BinObjMgt_Persistent and BinObjMgt_Position - to add possibility to write directly into the stream some data just after the attribute. Before this record a data-size is recorded.
BinMXCAFDoc package modifications to write BinMXCAFDoc_LocationDriver location in the same way as shapes write location data right after the attribute (empty) data in this new format.
BinTools package: creation of ShapeReader and ShapeWriter classes with same root class ShapeSetBase with ShapeSet class. These classes allows to write/read shapes directly to the stream. If some object is already in the stream, write a reference - relative position of the duplicated object. The old format of documents is still supported by Bin_ToolsShapeSet class.
PCDM_ReaderFilter - Allows the user to create a reading filter. It contains algorithm to browse labels tree quickly, without usage of referencing by entry-strings.
TDocStd, CDF and some other packages are changed for supporting reading filters API and options.
Tests, documentation and upgrade information are also added for both issues: 31839 and 31918 related to this commit.
- Added constructor to create axis by gp_Ax1

AIS_ViewController::handleXRMoveTo() now uses interface for picking by Axis explicitly
instead of emulating axis by point picking.
A table for fast access to the labels by entry is implemented in OCAF document. A method TDF_Data::SetAccessByEntries(true) fills-in a table for fast access to the labels. New labels, created later will be added to the table automatically. The method TDF_Tool::Label() will search the entry in the table and then, if not found, will call the old code. Disabling of usage of the table (by calling of TDF_Data::SetAccessByEntries(false)) cleans the internal table of entries - labels. By default, the table is not used.
This improvement is useful for large documents with a lot of labels, and if the application uses entries to get labels. The application should call TDF_Data::SetAccessByEntries(true) for a document and then, the method TDF_Tool::Label() called inside OCAF and XCAF will use the fast access to the labels and speed-up the application.
Also, the method TDF_Tool::Entry() is improved (by MPV).
Modified files:
- TDF_Data.hxx and cxx: the new methods SetAccessByEntries(bool), IsAccessByEntries() and GetLabel(entry) are implemented. No need to use the method GetLabel() directly. It is called in TDF_Tool::Label().
- TDF_Label.cxx: adding of a newly created label to the table of entries - labels.
- TDF_Tool.cxx: the method Entry() is accelerated (by MPV) and Label() is improved to call TDF_Data::GetLabel().
- DDF_DataCommands.cxx: a new draw-command is added SetAccessByEntry, which sets or unsets usage of the table for fast access to the labels. Usage of the draw-command is illustrated in a new test "bugs caf bug31920".
Tests:
- bugs caf bug31920: a new simple test to check TDF_Tool::Label() when fast access to the labels is on.
Doc:
- dox\upgrade\upgrade.md is extended for new information
Add SelectMgr_BaseIntersector class as base intersector that can have any geometry not only frustum.
Remove cached static array of selecting volumes from selecting volume manager. Keep only one the latest active selection volume.
Change initialization interface of active volume frustum inside of selecting volume manager: Init*SelectingVolume(), set required parameters, BuildSelectingVolume(). Mark existing BuildSelectingVolume() methods as deprecated.

while ANGLE library implements only OpenGL ES 3.0.
Added testgrid 'opengles2' dedicated to OpenGL ES 2.0 driver low-level functionality
and reusing a limited subset of passing tests from 'opengl' testgrid.
Currently testgrid is activated only on Windows platform when using ANGLE library
(properietary OpenGL ES drivers do not allow creation of restricted 2.0 context).

Common material definition now occupies 4x2 vec4 instead of 5x2 vec4.
Getters of Common material properties within Declarations.glsl
have been renamed to match PBR material syntax (e.g. take IsFront flag as function argument).
Auxliary macros (like occTextureColor()) has been renamed (like occMaterialBaseColor())
and adjusted to return material property directly instead of taking it as argument.
Visual selection has been moved out from Xw_Window constructor to OpenGl_GraphicDriver::InitContext().
Default Visual is now stored within Aspect_DisplayConnection.

IntTools_Context - maps of void* have been replaced by typed maps.
In test it should be taken into account that
lappend listmem [meminfo h]
checktrend $listmem 0 0 "Memory leak"
also gets memory (also about 100 bytes per iteration).
Added AIS_ViewController::MouseSelectionSchemes() property defining map of selection schemes for mouse+modifier combinations.
IsXOR flag has been replaced by AIS_SelectionScheme in interfaces.
Rubber-band selection with Shift key pressed now applies XOR selection scheme in in Draw Harness.
Command vselect has been extended to specify selection scheme by name.
Throughout the ChFi3d fillet creation functions there are two sets of unchecked
errors that can result in segmentation faults when geometry-creation problems
occur.
The first is that the functions ChFi3d_cherche_* may fail to find the requested
item: they silently return without setting the required reference, which is
then accessed by the algorithms. This can be caught with a conditional at the
end of the function that throws an exception if the required item was not
found.
The second class of unchecked error is the use of BRep_Tool::CurveOnSurface,
which may fail to create the required curve, returning a null handle. In many
cases in the existing fillet code this is not checked. This can be dealt with
by checking the returned handle using IsNull() and throwing an exception
if the call did not result in valid geometry.
Graphic3d_Aspects::ToSuppressBackFaces() bool flag has been replaced by
Graphic3d_Aspects::FaceCulling() property defined by Graphic3d_TypeOfBackfacingModel enumeration.
Graphic3d_TypeOfBackfacingModel_Auto corresponds to old ToSuppressBackFaces()==TRUE;
Graphic3d_TypeOfBackfacingModel_DoubleSided corresponds to old ToSuppressBackFaces()==FALSE;
Graphic3d_TypeOfBackfacingModel_BackCulled allows enabling back face culling regardless of Graphic3d_Group::IsClosed() flag.
XCAFDoc_VisMaterial::IsDoubleSided() bool flag has been replaced by
XCAFDoc_VisMaterial::FaceCulling() property defined by Graphic3d_TypeOfBackfacingModel enumeration.
glTF reader now maps "doubleSided" material flag into
Graphic3d_TypeOfBackfacingModel_BackCulled (forced back face culling) and
Graphic3d_TypeOfBackfacingModel_Auto (e.g. practically doubleSided as there is no closed/open info in glTF).
glTF writer by default writes materials as "doubleSided" save the Graphic3d_TypeOfBackfacingModel_BackCulled property set
(in future, extra logic might written for automatically defining singleSided materials for Solid B-Rep objects).
Removed obsolete unused types V3d_TypeOfPickCamera, V3d_TypeOfPickLight, V3d_TypeOfRepresentation, and V3d_Coordinate.
Deprecated types V3d_TypeOfBackfacingModel, V3d_TypeOfLight, and V3d_TypeOfShadingModel.

to be aliased as array of elements of mutable type.
Poly_ArrayOfNodes specializes this interface for collecting 2d/3d points with single/double precision.
Poly_Triangulation relies on this new class for definition of 3D nodes and UV coordinates
using gp_Pnt and gp_Pnt2d by default as before.
RWGltf_CafReader now fills in triangulation using single precision by default (as stored in the file).
OpenGl_LayerList::renderLayer() - fixed usage of wrong camera while rendering shadowmap,
and apply Z-Layer origin shift to shadowmap matrix while applying shadow.

when RG texture format is unsupported (OpenGL ES 2.0).
OpenGl_ShaderManager now allows compiling PBR shaders
using WebGL 1.0 + GL_EXT_shader_texture_lod extension.
PBR IBL baking GLSL program has been redisigned to use
if/else to avoid non-constant index expressions.
Diffuse baking implements packing float values into a temporary RGBA8 texture

## In order to contribute code to OCCT, you (or the legal entity you represent) must sign the Contributor License Agreement (CLA).
### What is the Contributor License Agreement and why is it necessary to sign it?
The Contributor License Agreement is needed to clarify the terms of usage of contributions by OPEN CASCADE SAS and the entire open source community.
The Contributor License Agreement clarifies the intellectual property rights applicable to contributions. It confirms that the contributor retains ownership of his contributions (the OPEN CASCADE company does not require exclusive copyright transfer for these contributions) and gives all rights to OPEN CASCADE to use the contribution. In turn, OPEN CASCADE guarantees the open source availability of all integrated contributions.
### How to sign the Contributor License Agreement
Accepting and signing the Contributor License Agreement is a prerequisite for contributing code. To sign the CLA, please register yourself first, and then follow the steps below:
1. Select the "Get Involved" menu
2. Download the Contribution License Agreement pdf file and print it
3. Read the agreement and sign it
4. Scan the signed CLA to a pdf file
5. If not yet done, log on to this website
6. In the CLA sending form, press the "Browse" button
7. Select your signed CLA file
8. Press "Send"
We will need some time to approve the CLA that you have submitted. You will be notified by e-mail when your CLA is approved and you are assigned the Contributor role.
### Q&A on the Contribution Agreement
**I want to contribute code that I developed as part of my job. Can I contribute this code?**
Yes, but as (under applicable legislation) your employer typically will own all intellectual property that you create as part of your employment, it is important that your employer has consented to your participation and contributions in the OCCT Project. That provides clarity to all parties involved.
**Can we sign a CLA to enable contributions from several employees in our company?**
Yes, if your company has several employees ready to contribute, a person representing your company can sign the CLA whereby your employer can specify and manage who is able to contribute from your company.
**I want to notify the OCCT Project of a bug I found. Can I report this bug?**
Yes, you simply need to register (you then become a Member) for entering a bug. The bug can be entered using our bug tracker from the Get Involved page. But please note that as a Member of this project, you have accepted the Terms and Conditions of this website, so the materials you provide must conform to these Terms.
**Can I terminate my Contributor License Agreement?**
Yes, you may terminate your Contributor License Agreement by sending a written notice through the contact form of this portal. The termination of your CLA will become effective not later than 5 days from the notice date. Please note, however, that all contributions you might have made to the OCCT Project before your CLA termination remain covered by that CLA.
In order to contribute code to OCCT, you must register on this [portal](https://dev.opencascade.org/) and sign the Contributor License Agreement (CLA).

Open CASCADE Technology (OCCT) is 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 is ideal for developing software dealing with 3D modeling (CAD), manufacturing/measuring (CAM), or numerical simulation (CAE).

## Packaging
You can receive certified versions of OCCT code in different packages:
- **Snapshot of Git repository:** Contains C++ header and source files of OCCT, documentation sources, build scripts, and CMake project files.
- **Complete source archive:** Contains all sources of OCCT, generated HTML and PDF documentation, and ready-to-use projects for building on all officially supported platforms.
- **Binary package (platform-specific):** In addition to the 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:
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 the documentation accompanying your version for details.
## Documentation
Documentation is available at the following links:
Documentation can be part of the package. To preview documentation as part of the package, open the 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 the environment variable PATH). Use the batch file `adm/gendoc.bat` on Windows or the Bash script `adm/gendoc` on Linux or OS X to (re)generate documentation.
- **Generate together with sources:** You need to have CMake and 1.8.4 (or above) installed on your system. Enable `BUILD_DOC_Overview` CMake parameter and set the path to Doxygen `3RDPARTY_DOXYGEN_EXECUTABLE`. Then build ALL or only `Overview`.
- **Read documentation in source plain text (Markdown) format** found in the subfolder `dox` or [GitHub Wiki](https://github.com/Open-Cascade-SAS/OCCT/wiki).
See [dox/build/build_documentation/building_documentation.md](dox/build/build_documentation/building_documentation.md) or [Building Documentation](https://dev.opencascade.org/doc/occt-7.8.0/overview/html/build_upgrade__building_documentation.html) 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/build/build_occt/building_occt.md](dox/build/build_occt/building_occt.md) or [Building OCCT](https://dev.opencascade.org/doc/overview/html/build_upgrade__building_occt.html) or [Building OCCT Wiki](https://github.com/Open-Cascade-SAS/OCCT/wiki/build_upgrade) for instructions on building OCCT from sources on supported platforms.
