Checking of number of knots is added. If number of knots more then allowed value, algorithm does not search distance between curves for each knot interval, but uses predefined sample point distribution.
This change was born in the scope of work on the issue 26329, but does not have direct connection to it. Therefore it has been postponed to be integrated later in its own context.
Test case for issue #28030
Purger has been disabled (in IntPatch_PrmPrmIntersection algorithm) if some points have been added in the Walking line (it is stupidly, first, to insert some points in the line and, after that, to delete points from this line).
Some improvements in IntWalk_PWalking::SeekPointOnBoundary(...) method have been made (see comments in the code for detail information).
Some test cases have been adjusted according to their new behavior.
The method BRepOffsetAPI_MakePipeShell::Generated now returns generated shapes for sub-edges and sub-vertices of sections.
The method BRepFill_PipeShell::BuildHistory is redesigned: now it builds generated shapes for sub-edges and sub-vertices of sections.
New Draw command "gensweep" is added to sweep commands for testing of history building.
Check for null shape has been added in the command addsweep implementation.
// eliminate warning
Test case for issue CR24932
Test case has been corrected.
- added implementation of mentioned methods for neutral point;
- sequence of detected objects was replaced by sequence of detected owner's indexes in AIS_InteractiveContext;
- commands vselnext and vselprev were corrected to update viewer properly;
- test case for issue #27530.
The algorithm in WorkWithBoundaries::BoundaryEstimation(...) did not take into account opposite directions of cylindrical axes (when the angle between them is obtuse). After the fix it does it.
Small correction of test cases for issue CR28009
The root of the problem is incorrect processing of cases when intersection line goes through the apex(es) of sphere. The fix improves this situation. The algorithm is taken from DecomposeResult(...) function (see IntPatch_ImpPrmIntersection.cxx file). Before the fix, faltering steps were done to solve this problem. As result, it worked in some particular cases. Now, its possibilities have been extended significantly.
Following changes have been made in the fix:
1. Class IntPatch_ALineToWLine has been rewritten cardinally. It touches as interfaces of existing methods as adding/removing some methods/fields. Correction touches both cases: going through seam of Cone/Sphere and through pole(s) of sphere. Old interface did not allow making some actions with analytical line (ALine), e.g. splitting it on several Walking-lines (WLine).
2. Restriction-line support has been removed from Implicit-Implicit intersection result (see IntPatch_Intersection::GeomGeomPerfom(...) method). It connects with the fact that the intersection algorithm itself returns precise intersection line in analytical cases (in compare with parametric intersector). Therefore, we do not need in additional (restriction) line.
3. New class IntPatch_SpecialPoints has been added. This class contains methods to add some special points (such as apex of cone, pole of sphere, point on surface boundary etc.) in intersection line (IntPatch_PointLine). It is based on the static functions, which already exist in IntPatch_ImpPrmIntersection.cxx file (these functions have been moved to the new class).
4. Method IntPatch_WLineTool::ExtendTwoWlinesToEachOther(...) has been renamed to IntPatch_WLineTool::ExtendTwoWLines(...). It is connected with changing main idea of the method. Now it allows extending WLine to the surface boundary or to the singular point (if it is possible): cone apex, sphere pole etc. Interface of this method has been corrected, too. At that, old functionality (extending to each other) has been kept. For implementation of this algorithm, new enumeration "IntPatchWT_WLsConnectionType" has been created.
5. Method IntPatch_PointLine::CurvatureRadiusOfIntersLine(...) has been added. See IntPatch_PointLine.hxx for detail information. It allows correct step computing depended on the local curvature of the intersection line. This method uses geometrical properties of intersected surfaces to compute local curvature. Therefore, it can be applied in wide range of cases even if the intersection curve is not represented in explicit form (e.g. in case of param-param-intersection).
6. Method IntSurf::SetPeriod(...) has been created.
7. Additional check has been added in Draft_Modification::Perform() method for better choice of correct fragment of intersection line for processing DRAFT operation.
8. New overload method IntPatch_Point::SetValue() has been added.
9. Some refactoring of the code has been made.
Creation of test case for issue #27431.
---------------------------------------------------------------------------------------------
Some test cases have been adjusted according to their new behavior.
tests\bugs\modalg_4\bug62
It is really IMPROVEMENT (but fortuitous).
tests\bugs\modalg_5\bug25838
The behavior of this test has been reverted to the state before fixing the issue #27341. Main problem has not been fixed in #27341. It was fortuitous improvement.
tests\bugs\moddata_2\bug565
Quality of intersection curve was not checked. And the curve is bad on both MASTER and FIX. Input data are really wrong: plane-like-cone. However, on the MASTER, four intersection curves (the quality is insignificant) are expected. On the fix, not empty intersection result is expected simply.
tests\boolean\volumemaker\A8
Differences in images and CPU is expected. Difference in images is expected to be fixed in the issue #26020. Now, we should apply this behavior.
Much CPU time is spent by IntTools_FaceFace::ComputeTolReached3d(...) and GeomInt_IntSS::BuildPCurves(...) methods calling. These methods are not touched by the algorithm. It is the result of change of intersection curve(s) form. However, the new Curve(s) seems to be valid and can be applied. As result, new behavior can be applied, too.
tests\boolean\volumemaker\F8
tests\boolean\volumemaker\F9
tests\boolean\volumemaker\G5
tests\boolean\volumemaker\G6
CPU difference is expected. Much CPU time is spent by IntPatch_PointLine::CurvatureRadiusOfIntersLine(...) method calling. This method is really new (it does not exist on the MASTER) and is really useful. Therefore, we should apply new behavior.
tests\boolean\volumemaker\G1
CPU difference is expected. Much CPU time is spent by IntTools_WLineTool::DecompositionOfWLine(...) and IntTools_FaceFace::ComputeTolReached3d(...) methods calling. These methods are not touched by the algorithm. It is the result of change of intersection curve(s) form. However, the new Curve(s) seems to be valid and can be applied. As result, new behavior can be applied, too.
tests\bugs\modalg_6\bug26619
Differences in images is expected. The test keeps its BAD status on the FIX. But the result on the fix is nearer to expected than on the MASTER. Issue #27014 is still actual. As before, it is not clear, why the number of entities is different. The number of section curves has not been changed. Interfered entities are the same as on the MASTER.
tests\bugs\modalg_5\bug25319_1(2)
The reason is described in the issue #27896.
Small correction in the test case
Implement new function to find Product_Definition_Shape entity.
Modify Reader to add possibility of import DGTs, connected to some geometry items.
Update test cases.
BRepGProps now ignores faces without geometric surface to avoid access violation.
BRepExtrema_DistShapeShape::DistanceMapMap() now skips comparison between void bounding boxes.
BRepBndLib::Add() now ignores useTriangulation flag for faces without geometric surfaces, and uses triangulation if any for updating of the box.
The SolidClassifier algorithm does not take into account the internal parts of the solid and its faces.
But in some cases the parts which are internal on some shapes can be included in other shapes of
the same solid with FORWARD/REVERSED orientation and therefore should be counted as well.
The fix changes the procedure of the initialization of the tree of bounding boxes of the edges and
vertices of the solid in SolidExplorer algorithm to treat the internal/external parts of the solid correctly.
Avoid getting non-existing array items. Use reference to array items instead of pointers where it is possible.
Create test case. Before the fix this test raised exception in debug mode.
Method WorkWithBoundaries::BoundaryEstimation(...) has been brought in balance with IsParallel(...) method, which checks if cylinder axes are parallel.
Added classes AIS_Animation, AIS_AnimationCamera, AIS_AnimationObjectLocatio.
Draw Harness command vanimation has been modified to manage animation timeline.
Command vfit has been extended with option -noupdate.
Formatting of vviewparams command output has been improved.
Functionality of commands vlocreset, vlocmove, vloctranslate, vlocrotate,
vlocmirror, vlocscale has been merged into vlocation/vsetlocation.
vlocation now can print the current local transformation of the object.
v3d/ivtk test group does not call vfit anymore.
Fixed misprint in test cases bugs/vis/bug24623_3 and bug25532.
While checking the section edges between pair of faces on coincidence with the
existing edges use for checking only the edges from these two faces.

Graphic3d_ZLayerSettings - public fields have been replaced by methods.
Added new property Origin defining local coordinate system for all Layer objects.
Syntax of Draw Harness command VZLayer has been redesigned.
Graphic3d_CStructure now stores bounding box with double precision floats.
OpenGl_BVHTreeSelector - frustum culling now works with double precision floats.

The following methods have been removed from Graphic3d_CView class:
TriedronDisplay(), TriedronErase(), ZBufferTriedronSetup(), TriedronEcho().
New class V3d_Trihedron has been added as replacement of removed OpenGl_Trihedron
which now uses Graphic3d_TMF_TriedronPers persistence.
AIS_InteractiveContext methods adding object to the context now throws Standard_ProgramError exception
if object has been already displayed in another context.
AIS_InteractiveContext::Remove() now NULLifies context assigned to the object.
AIS_InteractiveContext now inherits from Standard_Transient instead of deprecated MMgt_TShared
and defines C++ destructor instead of method Delete().
AIS_InteractiveObject - undocumented property State() has been removed.
Undocumented property Users() has been moved to AIS_IdenticRelation.
Draw Harness command vclose now clear AIS_InteractiveContext content
before nullifying it to ensure that objects have been properly removed.
AIS_MultipleConnectedInteractive now overrides method ::SetContext()
to assign context for children objects.
Virtual method *BinLDrivers_DocumentRetrievalDriver::Clear* now allows to Clear a cash data accumulated during a reading.
So, in successor class BinDrivers_DocumentRetrievalDriver this allows clearing the BinMNaming_NamedShapeDriver set of stored shapes when it is not needed anymore.
OpenGl_Structure::Render() and SelectMgr_ViewerSelector::checkOverlap()
now clip entire zoom/rotate persistence object
by checking anchor point with global clipping planes.
Image dump has been added to the new test case.
OpenGl_ShaderManager, per-vertex shading and per-fragment shading
- do not apply model-world matrix on the light sources
which are expected to be defined in world-space.
Now, the algorithm tries to estimate U- and V-ranges of future intersection curve(s) on the surface. This information is used in stop-criterium of the algorithm instead of full surface range used earlier. It allows reducing dependencies of intersection result on the surface ranges.
Tuning of test case bugs/modalg_6/bug27937_1
1. VRange of intersection curve has been limited. As result, too oblong intersection curve(s) will be never returned.
2. Now, purger algorithm is not called for lines obtained by Geom-Geom intersection method.
3. New statuses are entered in IntPatch_ImpImpIntersection class. It makes intersection algorithm more informative and flexible for using.
4. Method IntPatch_ImpImpIntersection::GetStatus() has been created.

1. Unification of trimmed and not-trimmed cylinders processing (IntPatch_Intersection::GeomGeomPerfomTrimSurf() method has been removed).
2. Interface of IntPatch_ImpImpIntersection::Perform(...) method has been changed.
3. Now, WLine purging is forbidden for Geom-Geom-Intersection.
4. Bnd_Range class has been created. See Bnd_Range.hxx for detail information.
5. Algorithm of AddBoundaryPoint function has been improved in order to obtain intersection points in both boundaries (VFirst and VLast of every surface).
6. Earlier, method Geom2dConvert::ConcatG1(...) increased resulted B-spline degree (in case of not succession of previous iteration). Now increased value has been limited by Geom2d_BSplineCurve::MaxDegree() value (max degree = 25).
7. Algorithm of B-spline closure definition has been changed in the methods Geom2dConvert::C0BSplineToC1BSplineCurve(...) and Geom2dConvert::C0BSplineToArrayOfC1BSplineCurve(...).
