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(...).

1) tests/boolean/volumemaker/C5
tests/boolean/volumemaker/C6
tests/boolean/volumemaker/E7
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).
Check for double solutions has been added in algorithms Extrema_ELPCOfLocateExtPC and Extrema_ELPCOfLocateExtPC2d
that find extrema between point and curve.
XCAFDoc_ShapeTool::Expand method now avoids creation of subshapes under assemblies.
XCAFDoc_ShapeTool::AddSubShape now avoids creation subshapes under all labels except for simple parts.
Use of input tolerance has been eliminated in Geom2dInt_GInter algorithm called from BRepClass_Intersector::Perform(...) method.
Now the input tolerance is used only for checking ON-status of classification.
AIS_Manipulator::ObjectTransformation() has ceased to use undefined point for myStartPick initialization within AIS_MM_Translation mode.
AIS_MM_Scaling cas has been merged into AIS_MM_Translation to reduce code duplication.
Extrema_ExtElC/IntAna_IntConicQuad are now used directly instead of more generic GeomAPI_ExtremaCurveCurve/GeomAPI_IntCS.
Deprecated functionality related to Local Context has been removed.
The following classes and types have been removed:
AIS_LocalContext, AIS_DataMapOfILC, AIS_LocalStatus, SelectMgr_SequenceOfSelector, SelectMgr_DataMapOfObjectSelectors.
Value AIS_DS_Temporary has been removed from enumeration AIS_DisplayStatus.
The following methods related to Local Context have been removed from AIS_InteractiveContext:
::HasOpenedContext(), ::HighestIndex(), ::LocalContext(),
::LocalSelector(), ::OpenLocalContext(), ::CloseLocalContext(),
::IndexOfCurrentLocal(), ::CloseAllContexts(), ::ResetOriginalState(),
::ClearLocalContext(), ::UseDisplayedObjects(), ::NotUseDisplayedObjects(),
::SetShapeDecomposition(), ::SetTemporaryAttributes(),
::ActivateStandardMode(), ::DeactivateStandardMode(), ::KeepTemporary(),
::SubIntensityOn(), ::SubIntensityOff(),
::ActivatedStandardModes(), ::IsInLocal()
and ::AddOrRemoveSelected() taking TopoDS_Shape.
The methods AIS_InteractiveContext::Display() and ::Load()
taking argument theToAllowDecomposition have been marked as deprecated;
the new methods without this unused argument should be used instead.
AIS_InteractiveContext::DisplayedObjects() - removed argument theOnlyFromNeutral.
SelectMgr_SelectionManager has been simplified so that now it support only single Viewer Selector.
The argument -local has been removed from Draw Harness commands vselmode, vremove, vdisplay, vdisplayall, verase.
New algorithms calculating global properties on mesh data have been added:
- BRepGProp_MeshCinert computes the global properties of polylines represented by a set of points;
- BRepGProp_MeshProps computes the global properties of a surface mesh.
Existing tool BRepGProp now automatically uses new algorithm for triangulation-only faces.
By default, algorithm will use exact geometry objects (surfaces), when it is available (as before the patch);
this behavior can be switched by a new flag UseTriangulation, forcing usage of triangulation instead of exact geometry when both defined.
Image_Color - removed semibroken summ/difference operators.
Image_Diff now uses signed integer for computing differnce between ubyte3 components;
properly compare squared tolerance.
Image_Diff - dropped declaration of Image_ColorXXX24.
RGB color difference is now computed using Chebyshev distance instead of Euclidean distance
Image_PixMap - added methods RawValue()/ChangeRawValue() returning a pointer
to image where specified pixel data is defined.
