Bnd_OBB constructor from Bnd_Box is fixed for VOID input.
DRAW command bounding command is adjusted:
- Support of old syntax 'bounding shape'is restored.
- Exception on VOID bounding box is avoided.
- Arguments are handled in case-insensitive way.
- Options -s, -perfmeter, and ability to set result as first argument are removed as redundant.
- Help is moved to command definition.
Separate command OCC29311 is added (in QADraw) to do the same as option -perfmeter did; tests are updated.
The following improvements have been introduced in Boolean Operations algorithm s:
1. UBTree is replaced with EBTree in Boolean operations to be able to add/remove elements into the tree of bounding boxes.
2. Repeated (nested) intersection of sub-shapes is performed with argument vertices whose tolerances increased during the operation.
3. The algorithms of Edge/Edge and Edge/Face intersection have been improved for the cases when the intersection point is located close to the edge boundaries .
4. New procedure has been implemented to ensure forced creation of Edge/Face common blocks in cases when the edge is really close to the face.
5. Post-processing of Face/Face intersection results has been improved.
6. Extension of the planar faces for Plane/Plane intersection is avoided.
7. Builder Face now better classifies potentially internal edges relatively to new faces with filtering by bounding boxes.
Side effect changes:
1. IntTools_ShrunkRange now keeps the length of the valid range of the edge.
2. The method BOPDS_DS::UpdateEdgeTolerance() has been removed as unused (replaced by the BOPAlgo_PaveFiller::UpdateEdgeTolerance()).
Test case for the issue 0029900.
Test case for the issue 0029711.
Adjustments of the existing test cases.
Avoid using uninitialized variables.
In implementation of DRAW command "mkplane", the case labels of the switch statement are corrected to use values of the enum matching the type of the switch argument.
NCollecton_DoubleMap has been extended with two new methods Find1() and Find2()
performing lookup and returning found key withoout throwing an exception
(similar to NCollection_DataMap::Find()).
ViewerTest_DoubleMapOfInteractiveAndName has been redeclared to define
Handle(AIS_InteractiveObject) key instead of Handle(Standard_Transient).
vtriangle and vsegment commands now share presentation created by vdrawparray command.
Added missing accessors to Graphic3d_ArrayOfPrimitives properties
VertexNumberAllocated(), EdgeNumberAllocated() and BoundNumberAllocated().
Fast rebuilding of the face is now avoided if its edges have been unified during the intersection.
Full rebuilding of the face is required in this case (using BuilderFace algorithm).
IntTools_Context::IsInfiniteFace() - Make the conclusion about infinity of the face basing on its bounding box only. No need to check NaturalRestriction flag.
Various performance improvements in STEP read/write algorithms:
- Search for the label of a shape or component shape is improved using map mechanism instead of brute force iteration.
- Invariant FindEntities() is moved out of the loop in the method getStyledItem in STEPCAFControl/STEPCAFControl_Writer.cxx.
- A pointer to the end of binders chain is added in Transfer_Binder class to speed up adding a binder to the chain.
- Small fixes are added to eliminate excess copying of handles, calls of handle DownCasts and so on.
Stack overflow is removed during destruction of STEP model with long chains of Transfer_Binder.
It is possible to use the Draw commands ReadStep and WriteStep to read/write from the session without accessing the disk file (use '.' for the file name).
Performance test cases for STEP reading/writing have been added.
Implementation of classes BSplCLib_Cache and BSplSLib_Cache is revised:
- Common functionality dealing with spans along one parametric direction is separated to new struct BSplCLib_CacheParams
- Empty constructors are removed; copying is prohibited
- Code reconsidering degree and other parameters on each call to BuildCache() is eliminated; curve parameters must be the same in constructor and all calls to BuildCache()
- Extra call to BuildCache() from constructor is eliminated
Font_BRepFont now uses a dedicated algorithm for text-to-BRep transformation instead of relying on ShapeFix.
It orders wires based on wire classification, analyzes internal zones and creates a few faces (if needed).
TKService dependency from TKShHealing has been dropped.
The algorithm has been corrected to avoid exception.
Now both Draw commands "brollingball" and "rollingball" give correct results.
Test cases "offset faces_type_a A3, A4, A9" are good now.
Name of the PROPERTY_DEFINITION entity for validation properties is changed to "geometric validation property" according to the current version of the recommended practices.
For compatibility with older definitions (with underscores) the check is made using string with underscores replaced by spaces.
Output information about failure during reading of external file has been added (it can be checked by using Draw command "tpstat").
If the reader cannot find an external file at the first found location
(using entity APPLIED_EXTERNAL_IDENTIFICATION_ASSIGNMENT) it checks other information about file path
(using entity DOCUMENT_FILE related with the above-mentioned entity) and uses a new location for import of the external file.
New class OSD_ThreadPool has been introduced to define a Thread Pool for multi-threading algorithm.
Thread Pool assigns a serial number for each thread allowing Multi-Threading algorithm to allocate thread-local storage variables as an array whose size is the same as the number of threads.
OSD_ThreadPool also redirects exceptions to a thread calling parallel execution and consistently initializes FPE exception handling.
New class Standard_Condition provides a platform-independent tool similar to Event in WinAPI.
A new auxiliary function Standard_Atomic_CompareAndSwap() has been introduced
for performing atomic compare and swap of integer number.
Standard_Atomic_Increment/Standard_Atomic_Decrement fallback implementation
using ASM code for x86 processors for GCC has been dropped;
instead, it is expected that GCC should be properly configured targeting modern x86 architectures.
OSD_Signal now declares fFltExceptions as thread_local variable accessible through OSD::ToCatchFloatingSignals() property.
Standard_THREADLOCAL macro (wrapping thread_local attribute) has been moved to public header Standard_Macro.hxx.
OSD_Parallel::ForEach() has been extended with new optional parameter theNbItems and uses OSD_ThreadPool::DefaultPool().
AIS_InteractiveContext::MoveTo() and ::Select() now do not highlight entities
when ::AutomaticHilight() option is turned off.
vselprops command has been extended with new arguments -autoHighlight and -highlightSelected
(vhighlightselected command is now deprecated).
Now vertex loops on surfaces of revolution are imported from STEP format in the same way as on spheres and b-spline surfaces: in case of a single vertex loop neutral bounds will be used.
Methods SelectMgr_SelectableObject::GetHilightPresentation(), ::GetSelectPresentation() and ::UpdateClipping()
have been corrected to copy clipping planes of the object into highlighting and selection presentations.
Since now a new WLine is not created if its start point lies in another earlier computed WLine. It allows avoiding creation of duplicate WLines in the intersection result.
<!break>
1. Methods IsOutSurf1Box(...), IsOutSurf2Box(...), IsOutBox(...) for classes IntSurf_LineOn2S and IntPatch_RLine have been created.
The "end" file from folder "de" has been corrected to exclude comparing the number of edges in the shapes from current result with test data.
"TODO messages generated for differences were removed.
Data exchange tests were regenerated.
The problem when object transformation was applied to the bounding box twice has been fixed in OpenGl_Structure.
OpenGl_ShaderManager has been extended with GLSL program drawing bounding box.
OpenGl_Structure does not create extra Groups for drawing bounding box.
Interface OpenGl_RenderFilter and its implementations have been merged into OpenGl_Workspace.
This limits flexibility of interface, but simplifies logic.
- OpenGl_RenderFilter_FillModeOnly flag replaces OpenGl_CappingAlgoFilter;
- OpenGl_RenderFilter_NonRaytraceableOnly flag replaces OpenGl_RaytraceFilter;
- OpenGl_RenderFilter_OpaqueOnly flag replaces OpenGl_OpaqueFilter;
- OpenGl_RenderFilter_TransparentOnly flag replaces OpenGl_TransparentFilter.
OpenGl_CappingAlgo now:
- avoids redundant Stencil clearing when Layer contains at least one transparent Element;
- renders semitransparent capping plane within transparent elements pass.
vclipplane command has been extended by new argument -transparency.
The code has been fixed to avoid taking a reference from a field of a temporary variable
(BRepApprox_ApproxLine::Point() returns non-reference structure).
readstl syntax has been modified, so that it creates a single-face triangulation by default.
The argument "trinagulation" is no more supported.
The new argument "-brep" has been introduced to generate
a compound of per-triangle faces instead (old default behavior of the command).
The algorithm has been improved for the cases when the intersection line goes through the cone apex.
<!break>
1. All special points are put to the ALine forcefully (if they are true intersection point). Currently this step has not been implemented yet.
2. Now the tolerance of IntPatch_Point (put into ALine) is computed in order to cover the distance between it and the correspond ALine.
3. Test cases have been created.
4. Procedure of trimming IntAna_Curve has been improved.
5. Criterion when the discriminant of IntAna_Curve can be considered to be equal to 0 has been improved.
6. Methods IntAna_Curve::FindParameter(...) (and IntPatch_ALine::FindParameter(...)) currently returns list of all parameters corresponding the given point (IntAna_Curve can be self-interfered curve). Before the fix, this method always returned only one (randomly chosen) parameter.
7. Interfaces of the following methods have been changed: IntAna_Curve::FindParameter(...), IntPatch_ALine::FindParameter(...), IntPatch_ALine::ChangeVertex(...), IntPatch_SpecialPoints::AddPointOnUorVIso(...), IntPatch_SpecialPoints::AddSingularPole(...), IntPatch_WLineTool::ExtendTwoWLines().
8. Following methods have been added: IntAna_Quadric::SpecialPoints(...), IntPatch_ALineToWLine::GetSectionRadius(...), IntPatch_SpecialPoints::ProcessSphere(...), IntPatch_SpecialPoints::ProcessCone(...), IntPatch_SpecialPoints::GetTangentToIntLineForCone(...).

They are real IMPROVEMENTS. In the FIX (in compare with MASTER), section result between pairs of faces f2&f6 (C5), f3&f7 (C6) and f1&f5 (E7) is closed. Separated test cases have been created in order to focus on the problem with section. Bug #28503 has been fixed.
Correction in test cases.
Argument of LowerCase() and UpperCase() is cast to int via unsigned char to avoid passing negative integer in the case if the argument char is in the extended part of ASCII table (which would result in undefined behavior according to C++ standard).
