Added a transfer for ShapeRepresentationRelationship in Transfer of MappedItem method,
in order to support link of components according to ISO 10303-203-2003.
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
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.
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.
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.
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.
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.
Possibility for adding LengthUnit info to XCAF document using special class XCAFDoc_LenghtUnit and XCAFDoc_LenghtUnitTool is implemented.
Package UnitsMethods is split: geom methods were placed to new file GeomConvert_Units which is in the toolkit TKXSBase, internal step scale factors was placed to StepData.
Updated UnitMethods to convert scale factor to different unit types.
Now, XSAlgo::XSAlgo_AlgoContainer is used to update unit info from static interface values.
New Draw command "XSetLengthUnit" and "XGetLengthUnit" for set or get XDE attribute.
Upgraded tests for STEP, IGES, OBJ, glTF, VRML formats to check area regressing with used unit.
Upgraded tests\de test cases to use any units in the "loop back" algorithms.
- Add support of the control directives ( "\X2\" "\X4" "\X\" "\P*\" "\S\");
- Make param "read.stepcaf.codepage" base for conversion inside StepData instead of CAF;
- Rename "read.stepcaf.codepage" to "read.step.codepage".
- Add ISO 8859-1 - 9 code pages for conversion
- Add Resource_FormatType_NoConversion format type, that indicates non-conversion behavior
- Update old test cases that contain control directives
Progress indication mechanism is refactored to support incrementing progress within multithreaded algorithms.
The class Message_ProgressIndicator is only an interface to the user application.
It accumulates the progress provided by progress scopes.
The counter is protected by mutex for thread-safety.
The new class Message_ProgressScope replacing Message_ProgressSentry should be used to advance the progress.
The scopes are nested to each other to reflect the nested nature of operations.
The new class Message_ProgressRange should be used to pass the progress to sub-scopes.
All OCCT algorithms involving progress indication have been updated to new API.
Improvements in Draw_ProgressIndicator:
- Separate console mode has been added in order to make possible to put the progress into std::cout instead
or in addition to the draw interpreter, instead of trigger option "-tclOutput".
- Treatment of Ctrl-Break signal has been added.
Now any operation can be aborted by Ctrl-C or Ctrl-Break keystroke.
Added new test case 'perf fclasses progr_par' for testing of parallel work of the progress.
Operators << for Handle(Message_Messenger) are removed; their use is replaced by use of Message_Messenger::StreamBuffer
Message_Messenger has been replaced by Standard_OStream within Interface_InterfaceModel,IFSelect,IGES,STEP dump interfaces.
Translation of the entities AXIS2_PLACEMENT_3D including in the entity CONSTRUCTIVE_GEOMETRY_REPRESENTATION_RELATIONSHIP was added.
Entity AXIS2_PLACEMENT_3D is translated to the planar face with axis equal to AXIS2_PLACEMENT_3D.
New parameter "read.step.constructivegeom.relationship" is added to enable this translation (by default it is OFF).
Added test bugs step bug29803
Changes for using Axis Placement(not used during creation of assembly) as transformation for root Shape Representation.
Test for bug 29068 and auxilary command are added.
"endl" manipulator for Message_Messenger is renamed to "Message_EndLine".
The following entities from std namespace are now used
with std:: explicitly specified (from Standard_Stream.hxx):
std::istream,std::ostream,std::ofstream,std::ifstream,std::fstream,
std::filebuf,std::streambuf,std::streampos,std::ios,std::cout,std::cerr,
std::cin,std::endl,std::ends,std::flush,std::setw,std::setprecision,
std::hex,std::dec.
Detection of specific case of error in the definition of transformation matrix describing position of the component within assembly, when it has Axis Placements swapped, is corrected to handle the case when one of these Axis Placements is contained in both Shape Representations (of the assembly and its component).
This allows the problematic STEP file to be translated correctly.
Added test bugs step bug30087
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.
Static function stepstrcmp() in StepData_StepReaderData.cxx is replaced by plain strcmp() to have the full strings compared (stepstrcmp() returned true if one of strings was longer than the other but common part was equal).
Protection is added to avoid exception for cases when representation entities are NULL
New macro Standard_FALLTHROUGH is defined for use in a switch statement immediately before a case label, if code associated with the previous case label may fall through to that
next label (i.e. does not end with "break" or "return" etc.).
This macro indicates that the fall through is intentional and should not be diagnosed by a compiler that warns on fallthrough.
The macro is inserted in places that currently generate such warning message and where fallthrough is intentional.
Doxygen comments are provided for this and other macros in Standard_Macro.hxx.
Corrections: to use fixed shape as result in the non-manifold mode was made.
Regression was due to using modified initial shape as result in the previous version OCCT. At present initial shape is not modified during ShapeProcessing. Therefore modification to use fixed result was made.
Additionally using of nonManifold flag is added to ShapeProcessing.
Code has been updated to remove no-op casts and implicit casts to Standard_Boolean.
Places of inproper use of Standard_Boolean instead of Standard_Integer
have been corrected:
- Bnd_Box, Bnd_Box2d
Bit flags are now defined as private enum
- HLRAlgo_BiPoint, HLRAlgo_EdgesBlock, HLRBRep_EdgeData, HLRBRep_FaceData
Bit flags are now defined as enum
- HLRAlgo_EdgeStatus, HLRBRep_BiPnt2D, HLRBRep_BiPoint
Bit flags are now defined as bool fields
- HLRAlgo_PolyData
Bit flags are now defined as Standard_Integer
- OSD_DirectoryIterator, OSD_FileIterator
Boolean flag is now defined as Standard_Boolean
- ShapeAnalysis_Surface::SurfaceNewton()
now returns Standard_Integer (values 0, 1 or 3)
- ChFi2d_FilletAlgo
now uses TColStd_SequenceOfBoolean instead of TColStd_SequenceOfInteger
for storing boolean flags
Method IFSelect_Dispatch::PacketsCount() has been dropped from interface.
ShapeFix_Solid::Status() has been fixed to decode requested status
instead of returning integer value.
TopOpeBRepBuild_Builder1 now defines map storing Standard_Boolean values
instead of Standard_Integer.
Persistence for Standard_Boolean type has been corrected
to keep backward compatibility:
- BinMDataStd, BinTools, FSD_BinaryFile
Broken Draw Harness commands vdisplaymode and verasemode have been removed.
BRepMesh_FastDiscretFace::initDataStructure() - workaround old gcc limitations
BRepMesh_IncrementalMesh::clear() - avoid ambiguity
Add special parameter, which allow reading of all top level (not shared by any other entities) solids (manifold_solid_brep) and shells (shell_based_surface_model).
The examples how to use a new parameter:
DRAW:
switch on a parameter:
param read.step.all.shapes On
update model to apply new parameter value:
newmodel
read as usual:
stepread test.stp res * // each top level solid or shell will be read as res_i shape.
or
ReadStep Doc test.stp
CXX Code:
switch on a parameter:
Interface_Static::SetIVal("read.step.all.shapes", 1);
read as usual
Do ProcessShape for non-manifold too,
Add binding of already written shared faces to STEP entity for non-manifold.
Minor correction of test case bugs/step/bug27329
Support of profiles for norms is removed
Getting rid of thread-unsafe static variables.
Sequence is not thread-safe. Replacing it with Vector.
Updating samples due to previous changes.
Resolving conflict with system environment.
